摘要
陇南的阳山金矿床是产于泥盆系浅变质岩中的特大型金矿床,通过对该矿床流体包裹体的温度、盐度、密度、成矿压力及δD值等方面的研究,综合特征表明成矿流体具有浅成、中偏碱性和弱还原环境的成矿特点,综合分析认为成矿可能主要与低温热液作用有关。
Yangshan gold deposit is a supper large gold deposit occur in Devonian epizonal metamorphic phyllite or limestone.In this paper, based on the studies of fluid inclusions trapped in quartzes and calcites, the ore-forming fluid characteristics such as temperature,saltness,density,pressure during mineralization and δD are described, and the origin of this deposit is believed to be mainly associatied with epithermal process according to the characteristics of the ore fluid witch show intermediate to alkali property and weak reduction environment.
