改造型矿床的成矿热液系统地球化学特征──以元阳金矿床为例

GEOCHEMICAL CHARACTERISTICS OF METALLOGENIC HYDROTHERMAL SYSTEM OF THE REFORMED DEPOSIT ─TAKING YUANYANG GOLD DEPOSIT AS AN EXAMPLE

热液改造型矿床在我国占有相当重要的地位。本文以云南元阳金矿床为例探讨了该矿床的成矿热液系统的地球化学特征。认为此矿床的成矿热液系统是岩浆热液和改造热液组成的混合热液系统，为热液改造型金矿床。

Qre deposits of hydrothermal reformation type have an very important position in China. Geochemical characteristics of metalloghenic hydrothermal system of them are discussed with yuanyang gold deposit as an example in this paper. It is believed that the metallogenic hydrothermal system of this deposit is a mixture one formed by magmatic and reformatiom hydrothermal fluids. And the deposit belongs to the gold deposit of hydrothermal─reformation type.
