| 摘 要： | 本文通过对四川省盐源县西范坪斑岩铜矿床多种类型包裹体的特征及其温度、压力、盐度、密度、氢、氧同位素组成、成矿流体沸腾等地球化学特点研究表明 ,西范坪铜矿床形成在浅成—超浅成、中—高温环境中。成矿流体具有高盐度、高密度的特点。成矿流体曾经多次发生沸腾。氢、氧同位素组成表明成矿流体主要源于深部的斑岩浆 ,在成矿过程中有地下水加入。

| Abstract: | The Xifanping porphyry copper deposit is located in the Xifanping area, Yanyuan County, Sichuan, China. Geochemical studies of various kinds of fluid inclusions in the deposit (characteristics, and their temperature, pressure, composition, salinity, density, hydrogen\|oxygen isotopes, ore\|forming\|fluid boiling features and so on) indicate that the deposit was formed in the medium\|high temperature, hypabyssal\|superhypabyssal environment. The ore\| forming fluid is characterized by high salinity and high density and repeated boiling. Hydrogen\|oxygen isotopes make it clear that the ore\|forming fluid came mainly form a porphyry magma of deep source, and a little bit underground water was involved in the ore deposition. |
