西藏驱龙斑岩型铜矿床成矿模式研究

摘要

冈底斯成矿带上的驱龙斑岩型铜矿床是中国目前探明的资源量最大的斑岩型铜矿床.通过研究矿床的成矿背景、矿床特征了解了矿床的基本特点和矿床形成的基础；通过研究矿床围岩蚀变及其与矿化的关系认识了矿床成矿特点；通过对成矿流体、稳定同位素等的研究厘清了矿床成矿物质来源、成岩岩浆来源.综合以上研究建立了矿床的成矿过程和成矿模式.%The Qulong porphyry copper deposit, tectonically situated in the Gandise metallogenic belt, has the largest amount of resources of its type in China. The characteristics and forming of the deposit are studied on the basis of the metallogenic setting. The metallogenesis is analyzed through the wallrock alteration and its relation to mineralization. The sources of ore-forming materials and diagenetic magma are clarified with study on the metallogenic fluid and stable isotopes. Based on the research, the ore-forming processes and metallogenic model is established.
