摘要
笔者通过对研究区地层及含矿性、古地理的演化及古气候等诸方面的特征研究,表明古地理环境对铝土矿的成矿控制作用,西南天山铝土矿产于石炭纪灰岩的古风化壳侵蚀面上,为一被动大陆边缘沉积型铝土矿。
The examination of ore potential, palaeogeographic evolution and palaeoclimates indicates the controls of palaeogeographic environments on the mineralization of the bauxite deposit in southwestern Tianshan Mountains, Xinjiang. The bauxite deposit in the study area occurs along the erosion surface of a palaeo-weathering crust of the Carboniferous limestones as a sedimentary bauxite deposit on the passive continental margin.
