摘要
一般认为铝土矿矿体厚度与矿系厚度成正相关关系,在矿系大于5 m的区域就有可能形成铝土矿体,但笔者通过矿产调查工作发现,织金地区打麻厂一带存在较大的矿系厚度大于5 m的区域,却未发现铝土矿。本文通过对比认为铝土矿成矿不仅与矿系厚度成正相关,还与基底岩性及古地貌关系密切,并对铝土矿的找矿方向提出建议。
It' s usually thought that bauxite orebody thickness has positive correlation with ore thickness, the bauxite orebody can formed in the area where the thickness of ore is more than 5m. But in Damachang area of Zhijin, bauxite deposit isn' t found although the thickness is more than 5m. Therefore, it' s thought the mineralization of bauxite is not only has positive correlation with ore thickness, but also has deep relation with basement lithology and ancient landform, the suggestions for bauxite exploration are given.
