Analysis of the paleogeographic environment factors for the auxite deposit in Jiagou Henan Province
The Jiagou bauxite deposit occurred in the paleo weathered erosion surface of ordovician carbonate rock,the ore-bearing horizon was the Benxi Group strata of Lower carboniferous series.The mine was a large bauxite deposit.The palaeogeographic environment of bauxite in this area is poorly studied.Summarize the previ-ous research results and basic data of mining area.Comprehensive study of geological characteristics,sedimentary facies,palaeoclimate,geochemistry and biology and ecology shows that the paleogeographic environment of the deposit was an sea-land interaction with humid and hot climate.The study degree of palaeogeographic environment in this area has been improved.It has important guiding significance of mine exploitation and deep prospecting.
