| 摘 要： | 仙人岩铝土矿床是遵义铝土矿中规模最大、以高铁铝土矿为主,产于碳酸盐岩古岩溶侵蚀面之上的沉积型一水硬铝石铝土矿床,其成矿时代属早石炭世大塘期.本文对仙人岩铝土矿床地质地球化学特征进行了初步分析,表明在大塘期前,由于加里东运动,息烽-遵义上升成陆,致使基底地层(∈-S)遭受长期的风化剥蚀,形成较为丰富的风化残积物和大小不等...

| Abstract: | Xianrenyan bauxite deposit is the biggest one in Zunyi,mainly is high ferrous bauxite deposit,occurs in the sedimentary diaspore bauxite deposit on the carbonate fossil karst erosional surface,the metallogenic epoch is Datang period of Early Carboniferous.In this paper,it did primary analyses to the geological and geochemical characteristics of Xianrenyan bauxite deposit,it’s reflected that because the caledonian movement,Xifeng-Zunyi rises to land before Datang period,causes the basement(∈―s) suffers from long time weathering erosion,forms many weathering saprolite and ancient karst depression,affords good condition for the formation of bauxite deposit.In the Datang period,the underlying basement shale affords material condition for the formation of bauxite deposit by weathering erosion and laterization. |
