摘要

火成岩中浸染状及网脉状金银矿床中，自然金常产在黄铁矿中。破碎带经历多次构造活动，经应力作用改造而成，从而也引起多次热液活动的发生。从玲珑和新城两矿区大量的岩矿鉴定资料来看，其中低温脉旁交代黄铁绢英岩化作用与金的矿化有关。按热液活动的产物，不同的共生组合分为三个阶段：第I成矿阶段。银金矿——绢云母——石英菱铁矿——黄铁矿阶段。第Ⅱ成矿阶段。银金矿——绢云母——石英——多金属硫化物阶段。第Ⅲ成矿阶段。石英——黄铁矿化作用阶段。

Abstract

The parameters of Mössbauer spectral determination of two groups of samples are recorded. One group of samples is gold bearing fractural quartzvein type and altered type with different phases of mineralization

of which eleven are collected in different positions in midpart of No. 1 body of Xincheng goldmine and of which eight are collected in Shangdong Linglong mine and Xincheng mine. The other consists of 5 samples of intact rocks in the drill holes of ZK103 and ZK92 in profile 183. The corresponding variation can be observed in spectral line width and the probability of recoilless for pyrite samples with different phases of mineralization. The data are useful for studying of mechanism of mineralization of goldmine. On the other hand the paper is a primary exploration for giving a quantitative indication of mineralization and alteration.
