Abstract:

Xicha，Ginchang Gou Gold ore deposit are belong to strata-bound break-alterationtapy，It's metallogenic times are in the early Yanshanian to lndo-chinese epoch，The informa-tion about the element abundance and 1tls evolution in stratiform indieate that the etallo-genic source materiab of the deposit have double features.some of them came from strtiform 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.δ³⁴O_H2O=5.3‰ ～ 66.4‰ ；δ³⁴S=一6.I‰.Fluid inclusions datas indicate that metallogenk fluid aremainly chlorinated water．metallogenic tempeture concentrate on the 142～ 290℃ .From this，we infer the ore—bearing solutions probale the mixture water of magmatic water and atmospheric precipitution．The ore-beafingsolutions possible came from the stratiform．
