摘要: 从母岩特征、研究区风化作用特点等方面对黔北务正道铝土矿的成矿作用和成矿过程进行了初步研究,认为务正道铝土矿的成矿母岩—下志留统韩家店群的海相页(泥)岩富含水云母是风化成矿的物质条件;矿源区母岩风化形成的富铝碎屑经剥蚀、冲刷、搬运再沉积过程对铝土矿的形成、富集和进一步纯化起着重要作用;进而建立了务正道铝土矿的成矿模式系列图。Abstract: Based on the character of primary rock and rockweathering, this article deals with the mineralization and the course of mineralizing for bauxite in the WuchuanZheng′anDaozhen area, Northern Guizhou. It is considered that metallogenic primary rock of bauxite in the WuchuanZheng′anDaozhen area is marine shale of lower Silurian Hanjiadian group which has a lot of hydromica, and it is the substance condition to form ore deposit. Bauxite from ore formation caused by weathering, breakage and transportation, segregation and purification to accumulation, consequently, the figure of metallogenic model for bauxite in the WuchuanZheng’anDaozhen area is established.
