摘要
研究了大降坪超大型黄铁矿矿床中Ａｕ、Ａｇ、Ｃｕ、Ｐｂ、Ｚｎ、Ａｓ等在不同岩石、矿石及黄铁矿中的含量。除Ｐｂ作为综合利用外，其余均为工业利用价值。原始热水沉积的条带状矿石与经后期热液叠加变富的块状矿石具有不同的微量元素组成，矿石与岩石的一些元素比值和图解可作为两类矿石成因的判据。
he contents and distribution of trace elements,such as Au,Ag,Cu,Pb,Zn,As etc in different rocks,ores and pyritehave been investigated.Exept that lead can be utilized,others are useless due to their low concentration,Ag might be enriched toa certain extent during the utilization of Pb.By means of trace elements,the banded ores can be distinguished from the massiveores enriched by late stage hydrothermal reform. The ratios and the diagrams of some elements can be used as the criteria for orig-in of the deposit.
