贵州二叠系龙潭组镓元素的赋存规律和成矿前景探讨

Discussion on Occurrence Regularity and Metallogenic Prospect of Gallium in Longtan Formation of Permian,Guizhou

镓元素在我国信息化建设的进程中起着十分重要的作用,其对于国防工业以及高科技产业而言不可或缺。该文主通过贵州遵义煤田底水—马场勘探区为例,对贵州省二叠纪龙潭组镓元素的赋存规律和成矿前景进行探讨。通过对贵州境内煤矿区地理分布以及底水—马场勘探区内镓元素的分布等分析表明,该区镓元素的赋存规律为在空间上存在成片性,在存在煤层上存在环境复杂性。煤层中镓元素含量超过30 g/t的伴生矿物一般工业要求,属于富集状态,有着较佳的成矿前景。

Gallium plays an important role in the process of information construction in China,and it is indispensable for the defense industry and high-tech industries.In this paper,taking Bottom Water-Machang exploration area of zunyi coalfield as an example,the occurrence regularity and metallogenic prospect of gallium in Longtan Formation of Permian,Guizhou was discussed.Through the analysis on the geographical distribution of coal mines in Guizhou and the distribution of gallium in Bottom Water-Machang exploration area,it is shown that the occurrence of gallium in this area is spatially fragmented,and there is environmental complexity in the presence of coal seams.The gallium content in coal seams exceeds 30g/t generally required by the industry,and thus it is in an enriched state and has good prospects for mineralization.
