在热液条件下,实验研究影响矿物的稳定性的主要因素、变化过程和特征以及矿物的共生组合演变,对于研究成矿作用的物理化学条件,进而探讨成矿机理,都具有重要意义,一、实验条件的选择我们过去研究资料认为,斑岩铜矿床的成矿温度主要为250～350℃.因此确定实验的温度为200～400℃,压力为50～350大气压.根据国内外对斑岩铜矿床中矿物包裹体成分的研究,成矿溶液中富含KCl、NaCl及多种重
Experimental study of the main factors influencing the stability of minerals, the changing process and characteristics of the minerals and the evolution of the symbiotic assemblages in hydrothermal conditions are of great significance for studying the physicochemical conditions of metallogenesis and exploring the ore-forming mechanism. The choice of experimental conditions Our past research data suggest that the porphyry copper deposit metallogenic temperature is mainly 250 ~ 350 ℃ .Therefore, it is determined that the experimental temperature is 200 ~ 400 ℃, the pressure is 50 ~ 350 atmospheric pressure.According to the domestic and foreign spot Study on the composition of mineral inclusions in the rock copper deposit, the ore-forming solution is rich in KCl, NaCl and various kinds of heavy
