[1] The enormously destructive tsunami of December 2004, caused by sudden motion of the Sunda megathrust beneath the Indian Ocean, raised concerns about tectonically induced tsunami worldwide. Submarine landslides may also trigger dangerous tsunami. However, the potential and repeat time for such events is in most places poorly known due to inadequate exploration of the sea floor and age constr...

In this paper, the physiography, geomorphological features, and sedimentary bedforms of offshore Egadi Islands (Italy) have been illustrated mapped through an integrated analysis high-resolution bathymetric, seismo-acoustic, sedimentological data. The study area is characterized by a wide, up to 25 km, continental shelf which separated NNW-trending linear incision, Marettimo Channel, along seve...

The Dacian Basin was uniquely situated to record late Miocene hydrological changes that influenced depositional environments and faunal dispersal patterns in Central Eurasia's mega-lake Paratethys. Differences between the high strontium isotope ratio (87Sr/86Sr) of waters from Lake Pannon local Carpathian rivers low 87Sr/86Sr Eastern Paratethys (Black Sea ‒ Caspian Sea) allow a thorough investi...

Organic matter (OM) and carbonate are the important organic inorganic components, respectively, in shales of upper fourth member Eocene Shahejie Formation, Dongying Depression, Eastern China. Their enrichment affects hydrocarbon generation capacity reservoir development shales. The mechanism sequence stratigraphy influence on OM deposition investigated this study. Based petrological, mineralogi...

The Late Mississippian-Permian Anadarko Basin formed in Texas and Oklahoma, USA as the result of inversion Neoproterozic Cambrian rift structures. Subsidence was driven by flexural loading Amarillo-Wichita Uplift, this uplift may represent easternmost element Ancestral Rocky Mountains system. northwestern part basin has generally been interpreted to have filled sediment derived from Front Range...

A multi-proxy analysis of two sediment cores from Rantin Lake are used to reconstruct past lake-level changes and to make inferences about millennial-scale variations in precipitation/evaporation (P/E) balance in the southern Yukon, Canada between 10,900 and 3,100 cal yr BP. Analyses of calcium carbonate and organic matter concentration, magnetic susceptibility, titanium content, dry bulk densi...

Abstract The Paleocene-Lower Eocene N'kapa Formation has long been considered as an important groundwater and hydrocarbon resource in the eastern edge of Douala Basin. present study’s aim is to establish a possible link between geological nature this formation quality potential aquifers using Gamma Ray well log, cuttings outcrops through sedimentology sequence stratigraphy studies. results obta...

Abstract Sedimentological and geochemical records are presented for an upper Paleocene to middle Eocene deep-water pelagic succession of the Pabdeh Formation in Paryab section, Zagros Mountains, NW, Iran. In this study, grain-size statistical parameters, cumulative curves, bivariate analysis on twenty-five sediment samples were used decipher depositional processes paleoenvironments. XRD fine-gr...

The northwestern Gulf of Mexico basin has emerged as an archetype example of a robust, progradational passive margin system that induces substantial translation over underlying detachments due to gravitational loading. Despite this recognition, the difficulties in deep imaging of seismic data have continued to obscure key features of this deformation. Megaregional, 2D, long-offset PSDM data hel...

Submarine gravity flow processes on carbonate platform slopes can lead to the deposition of calciturbidite and calcidebrite beds adjacent deep-water seafloor. Such deposits have been previously found occur more frequently during sea-level highstands, leading increased export carbonates deep sea interglacial periods. Here, we document a new occurrence these types event in cores near series volca...
