Magmatic and stratigraphic settings exert a first order control on the formation of various mineral deposit types. Some sating are rich in mineral wealth while others are barren. Stratigraphic setting is of particular importance where stratif&m or stratabound minerill deposits are concerned x orebodies are commonly restricted to specific stratigraphic intervals. For example. within the area bou...

We propose a workflow for updating 3D geological meshed models to test different layering scenarios and assess their impact on the simulation of CO2 injection. This operates tetrahedral mesh that encodes rock unit information as well physical properties. The alternative meshes are built by modifying input inserting new horizon defined scalar field. Modifying consistently model while keeping its...

The efficiency of different types of traps for catching of the Caspian Sea crayfish, Astacus leptodactylus eichwaldi, was investigated from Mar. 2002 to Feb. 2003. Totally 56 traps of four most commonly used types, "Rectangular trap", "Round trap", "Opera house trap" in two colors of "black" and "blue", and "Fathoms plus" only in black...

The complexity of stratigraphic architecture makes the geological modeling over-reliance on labor, this means more timeconsuming and inefficiency. It is a difficult problem in using only borehole data in engineering survey for computerized automatic modeling to quickly establish the stratigraphic model. We joined connectivity criteria, as well as virtual drilling method, using an improved “laye...

Recent studies suggest a marked expansion of glacial ice across much of Gondwana beginning in the earliest Permian. Because expansion of glacial ice results in a lowering of sea level, the imprint of ice expansion should be evident worldwide as significant exposure event, hiatuses, or other evidence for sea level drop at or near the Pennsylvanian–Permian boundary. This literature review investi...

The top of the Gething Formation is one of the more important formational picks routinely performed by the oil and gas industry during their exploratory and development drilling as this horizon is very c:on-tinuous through northeastern British Columbia and much of northern Alberta. The name Bluesky is given to the rock unit which occupies this stratigraphic level, namely a sandstone-conglomerat...

Many versions of the history of Americanist archaeology suggest there was a "stratigraphic revolution" during the second decade of the twentieth century—the implication being that prior to about 1915 most archaeologists did not excavate stratigraphically. However, articles and reports published during the late nineteenth century and first decade of the twentieth century indicate clearly that ma...

The shallow marine Late Holocene wedge of the northern Salerno Bay shelf (Southern Tyrrhenian Sea) discloses the presence of four decimetric shelf-tapering sand beds. Their internal features, depicted by cores analysis and their stratigraphic position, revealed by VHR seismic investigations, inferred sandy layers as being the result of flash deposition, storm controlled, thus episodic. Stratigr...

abderaz formation is one of the upper cretaceous formations in the kopet-dagh sedimentary basin. a stratigraphic section from the mentioned formation is selected for detailed systematic description with regard to echinoids. numerous well preserved representatives of the families mircrasteridae wright, 1857 and echinocorythidae lambert, 1920 are described from the ghaleh-zoo stratigraphic sectio...
