摘要
本文运用多种地球化学方法,分析所掌握的有关数据,以玉龙斑岩铜(钼)矿床的主要矿体—斑岩型和矽卡岩-次生富集型矿体为主要研究对象,追索玉龙矿床成矿物质的来源。最终判定玉龙矿床成矿物质主要来源于下地壳或上地幔,有少量上地壳围岩物质加入。但在不同类型的矿体中,不同来源的物质所占比例存在差异。
In this paper, the authors use kinds of geochemical methods to study the gained data, and take the main orebodies in the Yulong porphyry copper (molybdenum) deposit, such as porphyry type and skarn type orebodies, as studying objects. Finally, we conlude that there are two sources of ore forming material for the Yulong porphyry copper (molybdenum) deposit. The major source comes from the lower or upper mantle, and the minor part from the wall rocks. But the proportion of the different sources of ore forming materials is different at the different type orebodies.
