The Lithogenic Nature of Some Gold Deposits in Carbonaceous–Terrigenous SequencesLithology and Mineral Resources - Tập 37 - Trang 239-250 - 2002
S. G. Parada
Carbonaceous–terrigenous sequences hosting the largest gold deposits in Russia are divided for the first time into two lithochemical (normal potassic and anomalous sodic) rock types. It is shown that the type of terrigenous rock alkalinity is governed by peculiarities of the tectonic evolution of sedimentary-rock basins and stages of lithogenesis. The alkalinity type reflects the character of ore-...... hiện toàn bộ
Continental margins as global oil and gas accumulation belts: The West Pacific beltLithology and Mineral Resources - Tập 45 - Trang 465-485 - 2010
A. I. Konyukhov
Most present-day oil- and gas-bearing (petroliferous) basins are localized in one of the five global oil and gas accumulation belts confined to continent-ocean transition zones that existed in the Mesozoic and Cenozoic. Two meridional belts are located in the western and eastern peripheral zones of the Pacific Ocean with intense tectonic activity during the major part of the Mesozoic and Cenozoic....... hiện toàn bộ
Lower riphean low-carbonaceous shales in the southern urals: Raw material for the manufacture of porous rubbleLithology and Mineral Resources - Tập 35 - Trang 267-277 - 2000

A property of swelling on heating to yield firm lightweight granules has first been revealed for lowcarbonaceous shales (LCS) from the Riphean stratotype in the Bashkirian Megaanticlinorium, Southern Urals. These granules possess all technological properties of “keramzite” or claydite (an artificial, expanded clayey material) and can successfully substitute this material. Moreover, the procedure o...... hiện toàn bộ
