摘要
西藏冈底斯成矿带是中国西部地质工作程度极低的地区之一,但成矿条件有利。综合近年地质大调查工作的最新成果,在对冈底斯成矿带的成矿地质背景、成矿条件进行分析和研究的基础上,认为冈底斯是一个找矿潜力巨大的铜、铁、多金属成矿带。根据成矿作用类型将冈底斯主要的矿床类型分为与斑岩、弧火山岩、中酸性侵入岩和蛇绿混杂岩等有关的铜、铁、金、银多金属矿床;并根据其资源找矿潜力,在冈底斯成矿带中划分5个找矿远景区,指出铜矿、富铁矿、富银铅锌矿及金矿是冈底斯成矿带的优势矿种,斑岩铜矿、火山岩型铜矿是冈底斯成矿带中2个最重要的矿床类型。
Even though the Gangdise metallogenic belt is one of the regions studied in most degrees in western China, but the metallogenic conditions in Gangdise are hopeful. In this paper, based on the (updated) fruits of geologic survey and primary analysis of the metallogenic background and metallogenic conditions in the Gangdise metallogenic belt, according to mineralizing process, the authors divide the main deposit types in Gangdise as copper, iron, gold, silver polymetallic ore deposits concerned with porphyry, island-arc volcanic rocks, intermediate-acid intrusive rocks and ophiolite mélange and locate five (prospecting) regions in the Gangdise metallogenic belt, according to mineral resources prospecting potential. The authors point out that the copper ore, high-grade iron ore, silver-bearing polymetallic ore and gold ore are superior types in the Gangdise metallogenic belt, and that the most important deposit types in the Gangdise metallogenic belt are porphyry copper ore and volcanic rock copper ore. The authors confirm that the Gangdise metallogenic belt is of gigantic prospecting potential in copper ore, high-grade iron ore, (silver)-bearing polymetallic ore.
