摘要
本文系统地研究了铜山口铜(钼)矿床地质特征和成矿机制,探讨了构造、蚀变和矿化三者在时间和空间上的关系,推断了成矿物质来源和成矿作用机理。
Tongshankou copper (molybdenum) deposit is a skarn-porphyry composite one, whose wall-rock alteration and mineralization are of the charateristics of the ring-shaped zoning around the ore-forming host stock and polystage. Both ore-forming elements and magmatic complex body in the ore deposit came from the upper mantle or the lower part of the earth' s crust. The ore-forming fluid of the early period is mainly the primary magmatic water, consisting of the ore-forming fluid produced by the magmatic crystallization differentiation and ascending supracritical ore fluid from the deep magmatic chamber, and for the later period mainly is palaeogroundwater. The ore deposit resulted from the interaction between magmatic water and palaeogroundwater.
