西藏俄卡地银多金属异常区地球化学

ON THE GEOCHEMISTRY OF EKADI AG POLYMETALLIC ANOMALY AREA, XIZANG

异常形态、分布严格受推覆断裂控制,范围大、浓集中心明显,浓度变化及因子载荷表明。区内找Ag、Pb有利,而Sb又为其最佳指示元素。

The morphology and distribution of anomaly are strictly controlled by the nappe fauh, which is characterized by a large distribution range, an evident concentration centre and the evident change of concentration. The factor loading shows that this area is advantageous to the prospecting for Ag, Pb, and Sb is the best indicator element.
