Sediments from stable sand bars along a 40 km section of the Brahmaputra River in northern Bangladesh were analyzed for their major, trace and rare earth element contents to determine their provenance, compositional maturity, source area weathering and tectonic setting. The sedimentary provenance of the Uberaba Formation corresponds to a mixing of materials from the alkaline districts of the Alto Paranaíba and from the erosion of the Serra Geral Formation and the Canastra and Araxá groups. The rare earth element patterns showed negative Eu anomalies (0.57-0.71), indicating they were derived mainly from fractionated felsic rocks. 6. Such material, called detritus, consists of fragments of rocks and minerals. (1985) Petrology and provenance of Cenozoic sand from the Indus Cone and the Arabian Basin, DSDP sites 221, 222, and 224. gence of sedimentary provenance analysis as a distinct field of study was spurred by the publication of several monographs that originated at dedicated meetings, starting with the book Provenance of Arenites edited by G.G. Abstract Understanding sedimentary provenance is essential when investigating clastic strata. Subsequent milestones included Developments in Sedimentary Provenance Studies edited by A.C. Morton, S.P. Sediment and Sedimentary Rocks Sedimentary Rocks Rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. Outcrop samples contain subequal concentrations of Sm and Nd in the acid-soluble and silicate fractions. The samples are from the San Marcos arch, south-central Texas, at depths ranging from outcrop to 15,000 feet. Additional information could be obtained, however, from trace element ratios. The structural depression that occupies the Okavango Basin in southern Africa comprises a depo-centre within the intracratonic Kalahari Basin where sediments of the Cenozoic Kalahari Group have accumulated. and INGERSOLL, R.V. WELTJE, D. MUNSTERMAN The following concepts are outlined Based on comparable provenance signatures, the terrane is interpreted to have been conjugated to the northeastern South China Sea margin from the Mesozoic until the Oligocene spreading of the South China Sea. Diagenetic enrichment of Sm relative to Nd in the authigenic phases is the most likely explanation for the observed increase in Nd model ages in the sandstones. Interpretation of bulk‐sediment geochemistry is one of several approaches for determining sediment provenance. This study examined these issues from the perspective of detrital fingerprints (including geochemistry, heavy mineral, and zircon U-Pb geochronology) of Mesozoic to Cenozoic strata from Palawan Island and basins of the northern South China Sea. Sediment generation and sediment routing systems from a quantitative provenance analysis perspective: Review, application and future development, Constraining recycled detritus in quartz‐rich sandstones: Insights from a multi‐proxy provenance study of the Mid‐Carboniferous, Clare Basin, western Ireland, Unraveling the origin of the Parnaíba Basin: Testing the rift to sag hypothesis using a multi-proxy provenance analysis, Formation and paleogeographic evolution of the Palawan continental terrane along the Southeast Asian margin revealed by detrital fingerprints. 11. The multi-dating results revealed a broad, mixed source region located in the E, S and central Thomson Orogen. Model ages increase most between 5,000 and 10,000 feet, within the zone of intense smectite illitization. The provenance shift in the Drummond Basin coincides with a major intraplate tectonic event in central Australia, the Alice Spring Orogeny. On the contrary Co, Sc, and Cr are more enriched in basic rocks. Provenance analysis is an effective method for discriminating the types of the sedimentary mother rock, restor-ing the sedimentary environment, and determining the geographic location of the mother rock district. Deposition occurred under cool to semi-arid climatic conditions in an oxic environment. Geochemical signature of provenance in sand-size material in soils and stream sediments near the Tobacco Root batholith, Montana, U.S.A. Stream-driven gravelly traction carpets are expected to produce sheet-like units of clast- to matrix-supported conglomerate, characterized by a parallel or an a(p)a(i) clast fabric. 3. (2) During a period of relative tectonic quiescence, formation of a Late Jurassic carbonate platform started around the Oxfordian/Kimmeridgian boundary on top of the obducted ophiolites. SUCZEK, C.A. Role of the Dingle Bay Lineament in the evolution of the Old Red Sandstone of southwest Ireland. Understanding the origins, or provenance, of a sedimentary deposit is an important aspect of geology. U-Pb Ages and Sedimentary Provenance of Detrital Zircons from Eastern Hayfork Meta-argillites, Sawyers Bar Area, Northwestern California W. G. Ernst,1,* Cailai Wu,2 Min Lai,2 and Xin Zhang2 1. Additionally, Cycle 3 is revised here to largely be a continuation of Cycle 2-style basement-derived sedimentation, rather than recording a resumption of local volcanism, as per previous models. Neoproterozoic zircon ages can be associated either with provenance from the sedimentary succession of the Avalon Zone of eastern Newfoundland, or with provenance from felsic igneous rocks. The topic covers a broad range of geological disciplines including mineralogy, geochemistry, geochronology, sedimentology, igneous and metamorphic petrology, ... Data from such components can play a critical role in. Sedimentary provenance studies can provide a finely-tuned record of sediment sourcing and tectonism. QPA and the ‘Provenance Toolbox’ provide the compositional framework which is necessary for the characterisation of the erosional products. The late Eocene-to-early Oligocene Taveyannaz Formation is a turbidite series deposited in the Northern Alpine Foreland Basin (close to the Alpine orogenic front). Most signifi cant, our data suggest that U-Pb ages of detrital zircons in Ter-tiary clastic sedimentary units of the central Andes may provide a powerful new tool for chronostrati-graphic studies. This volume brings together new analytical approaches and describes how they can be applied to the study of petroleum systems. © 2008-2020 ResearchGate GmbH. However, tectonic discrimination studies now look set to be eclipsed by techniques which exploit the characteristics of individual grains, rather than bulk populations (see below). Provenance studies utilizing these new dating methods can provide valuable insights into the depositional environments of these rocks which in turn help describe the tectonic evolution of the Lake Superior region. The basin stratigraphy was subdivided into three sedimentary cycles. Provenance in geology, is the reconstruction of the origin of sediments.The Earth is a dynamic planet, and all rocks are subject to transition between the three main rock types: sedimentary, metamorphic, and igneous rocks (the rock cycle).Rocks exposed to the … Results of mineralogy and geochemistry of the Neogene siliciclastic deposits of the Tukau and Belait formations were studied with the objectives to identify the provenance, estimate the intensity of continental weathering and infer the influence of 2. The macroscopic provenance analysis (gravel composition analysis) is a very useful tool for the characterization of changes in sedimentary sources through time, Since the 1980ies detrital garnet chemistry is extensively used as a tool in sedimentary provenance studies, yet there is no clear-cut understanding of what garnet type originates from which host l, The Palaeozoic rocks of the Dingle Peninsula provide a record of the evolution of the Caledonides, Acadides and Variscides. Quartz-intermediate graywackes are indicators of Andean type continental margins and approximate the upper levels of continental crust in composition. In all samples, the acid-soluble Nd is more radiogenic than the Nd in the corresponding silicate fraction, and the difference between the two reservoirs increases with depth. Mountain uplift and unroofing caused the partly erosion of the Late Jurassic carbonate platform, the underlying ophiolites and the Triassic–Jurassic nappe stack consisting of outer shelf sedimentary rocks. It consists predominantly of andesitic clasts with conspicious augite and brown hornblende, but it also contains fragments of granite, metagabbro, mica-schist, serpentinite and glaucophane. The results from the component analysis of these Tithonian polymictic carbonate turbidites constrain a Middle to Late Jurassic orogeny in the Western Tethys realm with following geodynamic evolution: (1) The closure of the western part of the Neo-Tethys Ocean caused west- to northwestward-directed ophiolite obduction onto the wider Adriatic shelf from Middle Jurassic times onwards. Sandstone petrological analyses reveal a prominent provenance transition to an … LA-ICP-MS U-Pb zircon dating was performed on 27 samples (2,544 analyses in total) and revealed a complex overall age pattern dominated by <500 Ma ages, as well as several older populations, notably of ‘Pacific-Gondwana’ (~500-650 Ma) and ‘Grenvillean’ (900-1,250 Ma) age associations. Sedimentary provenance analysis is a powerful tool for reconstructing sedimentary source-to-sink dynamics based on the determination of mineralogical, geochemical, … This study highlights the need for a multi‐proxy provenance approach to constrain sedimentary recycling, particularly in compositionally mature sandstones, as the use of zircon geochronology alone would have led to erroneous provenance interpretations. Post-Dingle Group ORS groups in the north of the peninsula were deposited in a syn-rift footwall block to the main Munster Basin. Geochemical approaches have several advantages, including applicability to both matrix-rich sandstones and shales and ability to constrain provenance age and geochemical history. The Okavango Basin has been formed due to stretching and subsidence at an area of diffused deformation, southwestwards to the main East African Rift System (EARS). An abrupt change in the Sm-Nd data is observed from the Carrancas Formation’s oligomitic conglomerates (TDM ages between 2.7 and 3.3 Ga; εNd(550 Ma) values … Combined with zircon U–Pb data, it suggests that the basement rocks of Apulian-affinity nappes (Margna Sesia, Austroalpine) were the major sources of detritus, together with the Ivrea Zone and recycled Prealpine flysch, that contributed debris to the Northern Alpine Foreland Basin. This tangential shear stress is converted to dispersive pressure, which aids buoyancy and quasi-static grain-to-grain contacts in the support of the clasts within the gravel carpet. Young (Neogene), well-exposed and erosionally dissected turbidite successions like those of the Tabernas area, SE Spain, contain a wealth of information concerning the geometry and internal architecture of deep water successions. The Biella volcanic suite was the source of volcanogenic zircons. Three distinct groups are recognized on the basis of abundance: (1) quartz-poor graywackes (<15% quartz, average 58% SiO2, K2O/Na2O ≪ 1), (2) quartz-intermediate graywackes (15–65% quartz, average 68–74% SiO2, K2O/Na2O < 1), and (3) quartz-rich graywackes (> 65% quartz, average 89% SiO2, K2O/Na2O > 1). tion about the provenance of the Geste Formation and establish a maximum depositional age of late Eocene (ca. are reviewed and an additional case from the Lower Old Red Sandstone of southwest Ireland is presented. sedimentary rocks to look at provenance (e.g. Sediment Routing Systems (SRS) and Sediment Generation (SG) are two branches of sedimentary geology which are complementary, although their full integration remains incomplete. The integration of the two disciplines is fundamental to tackle some of the open problems in sedimentary geology, including (i) the dynamics regulating the generation and release of sediments from upstream catchments to the floodplains, (ii) particle trajectories, (iii) residence time and mineralogical modifications in temporary storage environments (iv) sediment selective extraction and (v) the shredding of environmental signal propagation in both (vi) actualistic and deep-time SRS. A slight modification of the Dickinson point-counting method (1970) as originally proposed by Gazzi (1966) enables loss of information to be avoided and the dependence of composition on grain size to be minimized. Geochemical and isotopic approaches to constraining provenance of sedimentary rocks complement the information inferred from petrography. The SG approach is required to quantify lithological controls on Qs, and include it into the stream power law. Simultaneously, the up-thrown (northern) block received sediments from more distant Archean sources in the Zimbabwe and/or Kasai cratons, (b) Hiatus in sedimentation occurred at both sites between ca. Sm and Nd reservoirs within the shale change considerably with progressive diagenesis. In the Inner Dinarides of southwestern Serbia, Tithonian polymictic carbonate turbidites, deposited in a deep-water foreland basin below overthrust ophiolites, contain Kimmeridgian–Tithonian shallow-water clasts, Triassic open-marine limestone and radiolarite clasts, and chrome spinels of a harzburgitic source (suprasubduction and MOR ophiolites). Geochemical data of heavy minerals usually show a wider distribution in the sediments than the data of heavy minerals measured in the bedrocks. The succession ranges from Early Ordovician deep-water sediments, through Silurian shallow marine to non-marine sediments and volcanic rocks to an Old Red Sandstone (ORS) succession topped by Carboniferous marine shales. The study of sedimentary provenance interfaces several of the mainstream geological disciplines (mineralogy, geochemistry, geochronology, sedimentology, igneous and metamorphic petrology). Sedimentary provenance data play a critical role in assessing paleogeographic reconstructions, predicting reservoir quality, subsurface correlation, mapping depositional system, characterizing crust that is no longer exposed, and ultimately, crustal evolution. Todd Bhatia 1983). Furthermore, the characterisation of lithological compositions and textures, and the ability to predict changes to these during burial diagenesis, are often key in the success of a petroleum system (Kettanah et al., 2014;Tobin and Schwarzer, 2014). Materials subject to study are as diverse as…Â, Research advance in sediment provenance of the Qiongdongnan Basin, Geochemical discrimination of clastic sedimentary rock sources, Reconstructing provenance interaction of multiple sediment sources in continental down-warped lacustrine basins: An example from the Bodong area, Bohai Bay Basin, China, Fingerprinting historical fluvial sediment fluxes, Sediment Provenance: Influences on Compositional Change from Source to Sink, Tracing tectonic deformation using the sedimentary record: an overview, Pattern of Geochemical and Sedimentological Variability of the Albian to Cenomanian Upper Bima Sandstone, Benue Trough, Nigeria: Implications on Tectonic provenance and Source Area Weathering, Silurian turbidite provenance on the northern Avalonian margin, Unraveling the origin of the Parnaíba Basin: Testing the rift to sag hypothesis using a multi-proxy provenance analysis, Geochemistry and detrital geochronology of stream sediments from East Timor: implications for the origin of source units, Petrography and geochemistry of feldspathic and mafic sediments of the northeastern Pacific margin, Petrofacies and Provenance of Late Mesozoic Forearc Basin, Northern and Central California, Exceptions to the Relationship Between Plate Tectonics and Sandstone Composition, Comparison of isotopic and petrographic provenance indicators in sediments from Tertiary continental basins of New Mexico, Isotopic provenance of sandstones from the Eocene Tyee Formation, Oregon Coast Range, Effects of sedimentary sorting on neodymium isotopes in deep-sea turbidites. Oligocene sediment pathways from source to sink crossed further crystalline basement units and sedimentary covers before entering the basin from the southeast. The provenance of the sedimentary material of sandstones is traditionally determined by petrographic methods. Res. This study highlights that deposition in sedimentary basins is not only controlled by host basin dynamics but can be fundamentally altered by extrabasinal processes and sediment supply. The work illustrates how the current, state-of-the-art technology can be effectively utilized to address ongoing challenges in petroleum geoscience. In this study, a comprehensive analysis of the basin succession was undertaken, including stratigraphic logging, petrographic, QFL, paleocurrent and facies analyses, as well as multi-method detrital geochronology to better understand the nature of the provenance changes, modes of the sediment transport, and depositional environments. This master thesis addresses questions of sedimentary provenance in Mandawa Basin and the offshore areas of Statoil, Bock 2. confirms the application and the importance of heavy minerals in sedimentary provenance analysis. Received on: 04/28/2017. The timing and nature of the provenance change recorded in the Drummond Basin are consistent with it being driven by the contemporaneous but far-field intraplate Alice Springs Orogeny of central Australia. The lack of compositional variability in mature sediments associated with Cambrian cratonic sequences in the United States makes traditional petrographic discrimination of sedimentary origin difficult. Their average chemical composition approximates the average composition of these arcs and that of tholeiitic andesite. ithology. Sun, and Y. Yan (2017), Sedimentary provenance constraints on drainage evolution models for SE Tibet: Evidence from detrital K-feldspar, Geophys. The carpet is thought to have a quasi-plastic rheology but behave much like a viscous fluid at high shear rates. Sedimentary rocks are derived from the erosion of other rocks and thus provide important records of the geological environment at the time they were de-posited. Multiple mineral chronometers were used to provide broad coverage of the closure temperature spectrum, from high-closure-temperature U-Pb zircon, through moderate-temperature U-Pb rutile, to low-temperature 40Ar-39Ar systems in muscovite and biotite. This study focuses on an example of a continental basin that was likely influenced by a far-field tectonic event that caused a major provenance change and altered basin evolution. SRS connect all the steps of the journey of sediments from their formation to final deposition in relation to the denudation of sediment sources, the transfer of erosional products and their final deposition. However, the multi‐proxy approach also helps constrain the sedimentary history, and suggests that not all grain populations were derived directly from their original source. Manuscript ID: 20170061. The youngest population contains both syn-volcanic and basement grains. To investigate potential metamorphic sources, 18 detrital rutile samples were analysed for a total of 1,431 analyses. Twenty-nine samples were collected from different stratigraphic formations and multiple basin locations, allowing 4-D insights into the propagation of detrital mineral age signals across the basin. Department of Geological Sciences, Stanford University, Stanford, California 94305-2115, USA; 2. 4. This study investigates the value added by bulk‐sediment geochemical analysis in interpreting provenance in a passive margin clastic basin, the Upper Jurassic–Lower Cretaceous deltaic sediments of the Scotian Basin. Grains with a Laurentian or a Caledonian affinity have likely been recycled through Devonian basins to the south. sandstone. Sedimentary response to a collision orogeny recorded in detrital zircon provenance of Greater Caucasus foreland basin sediments. Grains with a peri‐Gondwanan affinity appear to be first‐cycle and are potentially derived from south/southwest of the basin. The aim of this project is (1) to study the grain-size dependence of garnet composition and (2) establish new interpretation schemes that allow for better discrimination of the detrital garnet minerals and their potential host rock lithologies based on robust probabilistic models. A case history, volcanic Quaternary sands deposited in the Nankai Trough off south-western Japan, illustrates the application of the scheme. detailed studies of Precambrian sedimentary rocks (e.g. Lapur and Muruanachok sandstones (Turkana Grits), Turkana Basin, Kenya - Volume 156 Issue 8 - Prince C. Owusu Agyemang, Eric M. Roberts, Bob Downie, Joseph J. W. Sertich Corresponding Author. The paleocurrent data and lateral grading trends indicate most sediment was transported into the basin from its S/SW margin, implying long-distance transport (in excess of 470 km) and extrabasinal sediment supply. The effect of grain size on detrital mode data obtained by optical analyses. The extent (47,000 km2) of the coarse-grained, fluviatile, basement-derived sedimentation in the Drummond Basin is unusual, and poses problems regarding sediment sourcing and transport, as very few studies to date have documented such long-distance, coarse-grained sediment dispersal.
