| 摘 要： | 马攸木金矿床是西藏最近发现的首例大型独立岩金矿床.该文着重介绍了马攸木岩金矿床的矿体形态、矿石结构构造和矿石物质组分、金矿物的一般特征,并将马攸木金矿床的形成分为热液期、风化期和沉积期,其中与岩金矿形成有关的热液期至少可分为三个矿化阶段.论述了岩金矿床的流体包裹体特征、S和Pb同位素特征及Ar同位素年龄.初步认为该矿床属与地热活动有关的浅成中低温热液矿床.

| Abstract: | The Mayoumu gold deposit is an independent gold deposit newly found in Tibet. This paper deals mainly with the general characteristics about the form of ore bodies, fabric and component of ores, natural gold in the Mayoumu gold deposit. The ore-forming process is divided into three periods, that is, the hydrothermal, weathering and sedimentary periods. The hydrothermal period related with gold mineralization can be divided into three stages at least. The paper discusses the characteristics of fluid inclusions, sulfur, lead, oxygen hydrogen and Ar Ar isotopes dating in the deposit. The authors consider that the Mayoumu gold deposit is a meso epithermal gold deposit related with geothermal activities after the preliminary study. |
