摘　　要：根据古地磁、古构造、稳定同位素和元素地球化学特征,系统分析了黔中铝土矿成矿环境.认为该矿是在炎热潮湿气候条件下,于构造有利部位,发育岩溶洼陷,成矿元素Al、Si、Fe和有机质随着介质地球化学环境的变化,发生元素沉积分异作用,于泻湖潮坪环境中沉积.In the light of palaeomagnetism, palaeostrueture, stable isotope composition and element geochemical characteristics, the metallogenic environment of bauxite deposits in the central part of Guizhou province is systematically analysed. It is believed that under a hot and wet climate condition and in a favourable structural location (karst depression), the metallogenic elementa (Al, Si and Fe) and organic substances, in pace with the variation of the geochemical condition of the medium, formed the bauxite deposit due to sedimento-differentiation in a laggon flat environment.
