摘要
铁炉坪银矿床成矿溶液具中 -低温、低盐度特征 ,可能来自于岩浆期的热液。成矿作用受太古界太华群、燕山期岩浆活动和构造活动三要素控制 ,太华群和燕山期岩浆岩可能提供了矿源。矿床原生地球化学异常具 Ag,Pb,Cu,Zn,Au,Sb,As和 Hg多元素组合特征 ,异常分带序列自下而上为 Bi,Mo,Cu,Au→ Ag,Pb,Zn→ Hg,As。
The ore fluid of Tieluping silver deposit is salinity. It was probably derived from the deuteric hydrothermal fluid. The mineralisation was related to the strata of Taihua group, magma and structural activity of Yanshanian period. The primary anomalies of the deposit are of multi-element assembly. The zoning sequence of anomaly from up to down is Bi,Mo,Cu,Au→Ag,Pb,Zn→Hg,As,Sb.
