摘要
通过对西藏岗讲铜钼矿区复式岩体特征、矿化特征、成矿期次和后期脉岩与矿化之间的关系等的研究,初步划分了6次岩浆侵入期次和3次成矿期,分析了控矿因素,认为受近南北向和北东向断裂控制的英云闪长岩和花岗闪长岩脉与成矿作用关系密切,其形成时期是矿区主成矿期。
Based on research of the Tibet Gangjiang porphyry copper-molybdenum deposit composite porphyry body characteristics,mineralization characteristics, ore-forming stages, the relationship between late dykes and mineralization, Gangjiang deposit district initially is divided into six times magma intrusion and three mineralization stages. By analyzing the ore-controlling factors,the paper put forward that mineralization is closely related to tonality and granodiorite veins by controlled NS-trending and NE-trending faults. The tonality and granodiorite veins formation period is the main mineralization stage of Gangjiang deposit.
