马尾山铝土矿床地质特征

Bauxite Deposit Geological Characteristics in Mawei Mountain

通过对马尾山铝士矿区初步普查工作,共求获铝土矿资源量65.77万吨,同时在矿区内还共生有粘土矿产可综合利用.从成矿条件分析,马尾山铝士矿区早二叠世梁山期为滨岸沼泽相环境,具铝土质泥质相沉积特征.因此,在马尾山铝士矿区西南部的二仙崖一带、咸丰西南部的赶场溪一带和咸丰西部的龙家盖一带,成矿条件较好,资源潜力较大,应进一步开展铝土矿的矿产勘查工作.

Through preliminary mineral prospecting in Marwei mountain bauxite beds, 657 700 tons of bauxite have been explored.At the same time,within the same mining area,symbiotic clay mineral can be mined and utilized comprehensively.Though it is a smaller scale of orebodies,this bauxite mineral explora-tion,as the rare bauxite mineral in this area,has important guiding significance in the future corresponding and related work.Analyzed from the metallogenic conditions, this orebodies belongs to coastal swamp faci-es environment in the early permian liangshan period,which is characterized by bauxitic argillaceous faci-es.As a result, the better bauxite metallogenic conditions and better potential bauxite mining resources have been found in eerxianyan in the southwest part in of Xianfeng County,Ganchangxi in the southwest part of of Xianfeng County,Longjiagai in the western part of of Xianfeng County.The bauxite mineral ex-ploration work should be further carriedout.
