    西岔、金厂沟金矿床地质特征及成矿机理研究

    THE GEOLOGICAL CHARACTOR AND METALLOGENIC MECHANISM OF THE XICHA GINCHANG GOUGOLD DEPOSIT

    • 摘要: 西岔、金厂沟金矿床是层控破碎带蚀变岩型金矿,其成矿时代为印支期至燕山早期。地层岩石中元素丰度及其演化资料表明,本矿床成矿物质来源具双重性,即有来源于地层,也可能有部分来自岩浆岩。稳定同位素研究结果西岔金矿床δ34S=1.9‰-7.4‰;黑厂沟金矿床δ34S=3.3‰-5.1‰,二矿床疏同位素组成基本相近,表明硫源相似。δ34SH2o值=5.3‰-6.4‰;δ13C=-6.1‰流体包裹体研究表明,成矿流体主要为氯化物水型。成矿温度集中于142-290℃。由此推断矿液水可能是岩浆水与大气降水的混合水。矿液中碱可能来源于地层。

       

      Abstract: Xicha, Ginchang Gou Gold ore deposit are belong to strata-bound break-alteration tapy, It's metallogenic times are in the early Yenshanian to Indo-Chinese epoch, The information about the elememt abundance and it' sevolution in stratiform indicate that the metallogenic source materiab of the deposit have double features, some of them came from strtr form and perhaps parts from magmatic rocks. Stable isotopic data as follow; Xicha gold are deposit:δ34S=1.9‰-7.4‰; Jin Chang Gou:δ34S=3.2‰-5.1‰. It indicate this two ore deposit with similar sulphur isotopic component have the similar sulphur source. (δ18OH2o=5.3‰-66.4‰;δC13=-6.1‰ Fluiel inclusions datas indicate that metallogenic fluid nrc-mainly or idate water, metallogenic tempeture concentrate on the 142-290℃. from this, we infer the ore-bearing solutions probale the mixture water of magmatic water and anno spheric precipitution. The ore-bearingsolutions possible came from the stratifom.
