贵州道真县河照岩铝土矿床地质特征及找矿标志

Geological Characteristics and Ore Indictors of Hezhaoyan Bauxite Deposit in Daozhen,Guizhou Province

通过对黔北道真地区河照岩铝土矿床的地质特征研究表明,区内含矿体系整体为一套黏土岩-铝土矿-铝质岩组合,铝土矿体主要产于中二叠统梁山组地层中,矿体产状与围岩基本一致,呈似层状及透镜状产出。在结合前人研究成果的基础上,探讨了矿床成因,同时对该区的找矿标志进行了总结,以期为该区后期的找矿勘探工作提供某些启示。

This paper studies the geological characteristics of the Hezhaoyan bauxite deposit in the Daozhen area of northern Guizhou Province,the ore-bearing rock series is a set of clay rock-bauxite-Aluminum rock assemble,Bauxite bodies occur in middle Permian liangshan formation,and the orebody is parallel to the surrounding rock and occurs in a layered and lenticular shape.Based on the research work of the predecessors,the author has discussed the genesis of the deposit,at the same time,the prospecting mark of the area was summarized,so as to provide some inspiration for the prospecting exploration work in the later stage of the area.
