马攸木金矿床是西藏最近发现的独立岩金矿床。对马攸木金矿床热液成矿期各矿化阶段石英中的流体包裹体温度与压力、盐度与密度、包裹体成分和H、O同位素诸方面的初步研究表明,成矿流体属中低温(198～259℃)、低盐度(3.10～7.08%NaCl)、低密度(0.85～0.93g/cm3)的流体,属(SO42-)Cl--(K+)Na+水化学类型,成矿环境为低压(22.7～26.7MPa)浅成(0.825～0.971km)环境。成矿流体可能主要来源于与大气降水有成因联系的地下热水。马攸木金矿床可能是与热泉相关的浅成中低温热液矿床。
The Ma Yumu gold deposit is an independent rock gold deposit recently discovered in Tibet. Preliminary studies on the temperature and pressure of fluid inclusions, salinity and density, inclusions and H, O isotopes of quartz in the mineralized stages during the hydrothermal mineralization of the Mayoumu gold deposit show that the ore-forming fluids belong to medium- and low-temperature 198 ~ 259 ℃), low salinity (3.10 ~ 7.08% NaCl) and low density (0.85 ~ 0.93g / cm3) fluids, belonging to the genus (SO42-) Cl - Low pressure (22.7 ~ 26.7MPa) shallow into (0.825 ~ 0.971km) environment. The ore-forming fluid may come from the underground hot water that has genetic connection with precipitation. Ma Yumu gold deposit may be associated with the hot spring epithermal deposits.
