摘要
楚碲铋矿、赫碲铋矿是两种少见矿物 ,其化学成分特征是亏Bi而富S、Au、Cu等杂质 ,它们均呈细小的 (0 .0 5～ 0 .15mm)的嵌晶被包裹在黄铁矿晶体中 ,在黄铁矿 (单矿物 )中含量最高可达 2 30 0 μg/ g ,使其具有重要的综合利用价值。它们的生成是由于两种不同性质的初始热液在运移途中相遇 ,引起碲元素迅速淀积的结果。其化学成分特征反映出S、Au、Cu等都是该区可利用的重要有益组分 。
Tsumoite and hedleyite are seldom minerals, chemically characteristic of poorness in Bi and richness in S, Au and Cu and generally taking themselves as the form of 0.05-0.15mm inset within single pyrite mineral. The grade may reach 2300μg/g, so that they are both worth being comprehensively used. Their genesis resulted from the meeting of two different original hydrothermal solutions during transportation to lead to precipitation of Te. Useful components, such as S, Au and Cu, stand as a clue in Guantian district to searching for pyrite deposits.
