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。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.
