Abstract

Bauxite rocks of the pre-Jurassic complex of the Urmano-Archinskaya oil and gas zone of the West Siberian Plate, which mainly formed due to redeposition of the products of crust weathering into karst traps, are considered. Igneous rocks of the intermediate composition and shales exposed in erosion–tectonic uplift of the basement to the northeast of the studied area could be the parent rocks. The aluminous composition and reservoir properties of bauxite rocks are due to filtration of hydrothermal solutions at the intermediate or deep burial diagenesis.

西西伯利亚板块古生界与中生界接触带的铝土矿储层

摘要

考虑了西西伯利亚板块Urmano-Archinskaya油气区侏罗纪前综合体的铝土矿岩,其主要是由于将风化壳产品重新沉积到岩溶圈闭中而形成的。在研究区东北部地下室的侵蚀-构造隆升中暴露的中等组成的火成岩和页岩可能是母岩。铝土矿岩的铝成分和储集层性质是由于在中等或深埋成岩作用时热液的过滤作用。
