Recycled sediments from the Upper Jurassic to Lower Cretaceous of the Qinling orogen most likely supplied the Jurassic to Early Cretaceous zircons observed in the NWSB. (3) Detrital zircon age distributions in Lower Cretaceous sediments record a pro-foreland basin setting The Upper Cretaceous sediments from the Akukwa-2 well in Anambra Basin, southeastern Nigeria were characterised using a suite of palynological, organic geochemical (Rock-Eval-type pyrolysis, GC-MS and open system pyrolysis-GC), and organic petrographic analyses (vitrinite reflectance measurements). The pyrolysis data revealed that the Nkporo and Mamu sediments have fair petroleum generation. The statement by Calvert and Pedersen (1996) that bottom sediments of permanently anoxic basins show no enrichments and have Mn concentrations that are controlled solely by the alumosilicate fraction is only valid for carbonate-free sediments. Mn / Al ratios of coccolith-containing samples from several Black Sea Unit 1 cores (Mn / Al = 0.13 to 0.20) are higher in Mn than average shale (0.096. Maio is unique among the Cape Verde archipelago as it hosts a complete sedimentary sequence resting on ocean floor extending to the volcaniclastic sediments that record emergence of the oceanic island (Fig. 1, Fig. 2).These outcrops offer the only opportunity to study exposed deepwater Cretaceous successions at outcrop in the Mauritania-Senegal-Guinea Bissau-Conarky (MSGBC) Basin

  4. The Cretaceous The Cretaceous period features a particularly interesting climatic episode in the Earth's geological history. It follows the Jurassic Period, better known as the time the dinosaurs inhabited Earth and spanned the period between 145.5 and 65.5 million years ago. The Cretaceous is the last period of the Mesozoic Era, which ends with a well-known mass extinction event. At the end.

Background. The concept of the oceanic anoxic event (OAE) was first proposed in 1976 by Seymour Schlanger (1927-1990) and geologist Hugh Jenkyns and arose from discoveries made by the Deep Sea Drilling Project (DSDP) in the Pacific Ocean. It was the finding of black carbon-rich shales in Cretaceous sediments that had accumulated on submarine volcanic plateaus (Shatsky Rise, Manihiki Plateau. The Great Valley Sequence of California is a 40,000-foot (12 km)-thick group of related geologic formations that are Late Jurassic through Cretaceous in age (150-65 Ma) on the geologic time scale.These sedimentary rocks were deposited during the late Mesozoic Era in an ancient seaway that corresponds roughly to the outline of the modern Great Valley (Central Valley) of California However, following standard practice for sedimentary Hg studies 1,5, after normalizing sediment [Hg] to the sediment wt% total organic carbon, we observed a distinct pattern of increased.

Permian-Cretaceous sediment of the Bintuni Bay based on biostratigraphy. Data used in Data used in this paper is mostly secondary data obtained from National Data Center and an oil com The mid-Cretaceous period was a time of abnormal polar temperature warming and consequent global oceanic anoxia that enhanced the widespread accumulation of organic matter-rich marine sediments. Gravity modeling suggests 4.5 to 7 kilometres (2.8 to 4.3 mi) of Jurassic and Cretaceous sediments in the sedimentary section of the mountain, with lithologies including limestone, dolomite and sandstone. In the north, these sediments are blanketed by basalt flows from the late Neogene and Quaternary sedimentary deposits from the Tripoli-Homs Depression, that separate Mount Lebanon from the.

Cretaceous sediments which underlie the Deccan Traps are exposed in the eastern and western margins of the basin and are also encountered in the subsurface. The paleogeographic reconstruction of the Cambay Basin suggests that the northern part, possessing a thin cover of Cretaceous sediments, has meagre petroleum prospects. However, the southern part of the basin, where more than 1,000 m of. From the DSDP Legs 1, 11, 13, 17, 25, 27, 32, 36, 41, 43, 44, 50, and 62 the Lower Cretaceous foraminifers have been investigated for biostratigraphical, taxonomical. sediments. Thus, when mid-Cretaceous sediments and basalts were cored from Allison Guyot during Ocean Drilling Program (ODP) Leg 143, it allowed us the opportunity to add to the meager subset of Pacific paleomagnetic data of that age. Hole 865A (18.44°N, 180.44°E) was drilled into the center of Allison Guyot, located in the west-central Pacific Ocean within the Mid-Pacific Mountains province. Other sites in the western Caribbean suggest that normally quiet, deep-water sediments were drastically disturbed right at the end of the Cretaceous, and the disturbed sediments have the iridium-bearing layer right on top of them. At many sites from northern Mexico and Texas, and at two sites drilled on the floor of the Gulf of Mexico, there are signs of a great disturbance in the ocean at the.

If you know the answer to this question, please register to join our limited beta program and start the conversation right now In particular, the Cretaceous Shimanto AC is composed of several coherent and mélange units (e.g. Taira, Katto, Tashiro, Okamura, & Kodama, 1988), with the former consisting almost entirely of terrigenous clastic rocks, and the latter comprising a mixture of oceanic basement, pelagic-hemipelagic sediments, and terrigenous clastics that retain little of the original sequence of the OPS. Thus. In Cretaceous black shales, organic carbon is noticeably (one or two orders of magnitude) concentrated relative to adjacent sediments. To our knowledge, the maximum content of organic carbon in Cretaceous black shales is more than 50%, which was observed at DSDP site 367 in the Cape Verde Basin, off northwest Africa. 18 ) In that example, the organic matter probably constitutes 70% or more of. Upper Cretaceous volcanogenic sediments cored from the archi-pelagic aprons of the Line Islands chain (Hole 315A and Site 316) consist primarily of redeposited material comprised of altered volr canic glass, feldspars, mafic minerals, clays, and other products of alteration. Well-developed current structures and hyaloclastic tex- tures are common. The sediments were apparently deposited.

This timing also matches the timing concluded from an analysis of the Cretaceous sediments of the Great Artesian Basin, Australia. 22 Of course, considering how the waters of the Flood would have moved across the continent, eroding sediments from some areas and depositing them in others, it is unlikely that that rocks labelled Upper Cretaceous in Western Australia were deposited at exactly the. The Western Carpathian Meliata Superunit (Meliaticum) includes a heterogeneous group of units—the blueschist-facies Bôrka Nappe and the very low-grade chaotic complexes—polygenous mélange containing material derived from various tectonic settings (Jaklovce Unit) and Jurassic oceanic sediments with olistostrome bodies (Meliata Unit s.s.).

The Cretaceous sediments are dominantly a turbidite unit made up of shale-sandstone interbeds. It is a very extensive unit in the Pontide region. Due to its turbiditic character and variable burial history in different parts of the region, organic geochemical parameters change drastically from one area to another. The TOC values range from 0.09 to 2.14%, averaging 0.60%. Organic matter varies. Approximately 700 m of Upper Cretaceous laminated biogenic sediments, mainly consisting of calcareous nannoplankton, dispersed biogenic silica, planktonic foraminifers, and marine organic matter, were deposited in the Tarfaya Basin, with sedimentation rates exceeding 10 cm/kyr in the depocenter of the basin near the town of Tarfaya [Leine, 1986; Kuhnt et al., 1997, 2005; Kuhnt, 2001]
