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。 Based on the characteristics of various types of inclusions and their geochemical characteristics such as temperature, pressure, salinity, density, hydrogen and oxygen isotopic composition and fluid boiling in the Xifanping porphyry copper deposit, Yanyuan County, Sichuan Province, , Xifanping copper deposit formed in shallow into - super-shallow into, medium-high temperature environment. Ore fluid has high salinity and high density. The ore-forming fluids have been boiling many times. Hydrogen and oxygen isotopic compositions indicate that the ore-forming fluid is mainly derived from porphyry in the deep, and groundwater is added during mineralization.
