摘要
夹沟铝土矿赋存于奥陶系碳酸盐岩古风化剥蚀面上,含矿层位为上石炭统本溪组,为一大型铝土矿床.查阅前人对该区的研究成果,结合矿区大量基础资料,从矿床地质特征、沉积相、古气候、地球化学、生物生态等多角度开展综合研究,表明该区矿床古地理环境是气候湿热的近海陆交互环境.通过对其古地理环境的分析,提高该区古地理环境研究程度,也为后续矿山开发利用和矿区深部找矿提供指导.
Abstract
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.
