摘要
贵州省道真县燕子岩铝土矿是渝南—黔北铝土矿成矿区的组成部分之一。文章从地层岩性、构造、含矿岩系、矿体特征、矿石质量、围岩蚀变等方面研究了燕子岩铝土矿的地质特征,研究表明燕子岩铝土矿是一个品位不高、厚度不大的中型铝土矿矿床,沿走向及倾向双向挠曲是它的一大特色。并进一步对其成矿原因进行了探讨,研究表明包含燕子岩铝土矿在内的整个渝南—黔北铝土矿为中二叠统梁山期产于页岩、灰岩古风化壳侵蚀面上的沉积型铝土矿。
Yanziyan bauxite in Daozhen county of Guizhou Province is one of the components of south Chongqing - north Guizhou mineralization area. In this paper, the author studies the geological characteristics of Yanziyan bauxite from lithology, structure, ore - bearing rocks, ore bady characteristics, ore quality, wall - rock alteration and so on, studies have shown that Yanziyan bauxite is a medi- um -sized bauxite deposits, which is not high,the thickness is not large, two -way deflection along the strike and the tendency is a major feature. And exploring its mineralization causes, studies have shown that include Yanziyan bauxite of all the south Chongqing - northGuizhoubauxite are the sedimentary bauxite which produce of shale and limestone ancient weathering crust erosion surface in middle Permian liangshan time.
