Abstract The Miocene Zhujiang Formation is the key horizon for oil and gas exploration in Pearl River Mouth basin of northern South China Sea. With help core observation, seismic attributes various analytical data, sedimentary facies marks, distribution depositional model forced regression basin, Sea, have been studied. Forced regressive deposits were formed during period when relative sea leve...

The Kashkan Formation (Paleocene to Middle Eocene), consists of conglomerate, sandstone, and siltstone in the Zagros Folded zone, southwest Iran. Type of the sedimentary facies, architectural elements and trace fossils show that Kashkan deposits were formed in a low sinuosity braided stream system, with north to south flow direction. The formation displays coarsening-upward succession reflects ...

Stationarity of the random function is the key property of stochastic models to the extent that wrong hypotheses could lead to very unrealistic reservoir modeling for flow simulations. When non stationarity is suspected at the scale of the domain to be modeled, geologists usually propose either geological drift or seismic attributes to constrain stochastic models. However, in both cases, confid...

Abstract ––A large regional-scale Ordovician continental basin has been revealed for the first time in Siberia. Sedimentary structures rocks of Tyva represent deposition environments rivers, oxbow lakes, dunes, river deltas, tidal, and coastal plains. Ichnofossils record a succession from freshwater (limnic-fluvial) to deltaic tidal facies. Integrated studies sedimentary Central show that they ...

[1] Sedimentary molybdenum, [Mo]s, has been widely used as a proxy for benthic redox potential owing to its generally strong enrichment in organic-rich marine facies deposited under oxygen-depleted conditions. A detailed analysis of [Mo]s–total organic carbon (TOC) covariation in modern anoxic marine environments and its relationship to ambient water chemistry suggests that (1) [Mo]s, while use...

dalichai formation at the rey-abad section (northeast shahroud) along the principal road of the mayamey-jajarm has a thickness of 166 meters .in this section, middle to upper jurassic carbonate rocks are well exposed and is typically composed of massive to medium-bedded limestones with thin shale interbeds. in the studied area and most places of this region, the lower boundary of dalichai forma...
