霍各乞铜多金属矿床是以海底火山喷发沉积为主,后经区域变质和岩浆热液改造的层控矿床。作者从含矿岩系特征分析了沉积成矿期流体、区域变质改造期流体及岩浆热液改造期流体来源等问题,并运用测试、热力学计算、图解相结合的方法,计算出各成矿期成矿流体的 t、p,以及 pH、E_h、fs_2、fo_2等物理化学参数。为矿床成因研究提供了众多有益的实际资料。
The Huoguo Qi copper polymetallic deposit is a stratiform deposit controlled mainly by submarine volcanic eruptions and then transformed by regional metamorphism and magmatic hydrothermal fluids. Based on the characteristics of the ore-bearing rocks, the authors analyzed the fluid during the sedimentary mineralization, the fluids during the metamorphism and alteration, and the sources of fluids in the magmatic hydrothermal reformation period. Using the methods of testing, thermodynamics and illustration, T, p, and pH, E_h, fs_2, fo_2 and other physicochemical parameters of ore-forming fluids. It provides many useful practical data for the study of deposit genesis.
