摘要
西藏马攸木金矿床的热液期可初步分为5个阶段:氧化物阶段、金 黄铁矿阶段、银金 硫盐阶段、贫金硫化物阶段和碳酸盐阶段。对各阶段流体包裹体的一般特征、成矿温度与压力、盐度与密度、气液相成分、氢氧同位素特征的研究,表明马攸木金矿床在成因上属浅成低温热液矿床。
Ore-forming process of Mayoumu gold deposit can be preliminarily divided into five stages: oxide, gold-pyrite, silver-gold-sulfosalt, poor gold sulfides and carbonate stage. This paper mainly deals with the fluid inclusion geochemistry of Mayoumu gold deposit in Tibet, including common characteristics, temperature, pressure, salinity, density, gas and liquid composition and H,O isotopes. We can draw a conclusion that Mayoumu gold deposit may be an epithermal deposit.
