引言近年来,对于岩浆期后热液矿床成因的理论有了更深刻的认识.霍兰德(1972)总结了对硅酸盐熔融体和共存的液相之间贱金属分配的数量所做的研究,结果表明,一个花岗质熔融体内,在地质上数量适宜的H_2O和溶解的氯化铁离子可以从“正常的”花岗质熔融体内提取足够数量的金属,以形成一个相应大小规模的岩浆期后矿床.威特尼(1975)证实了伯纳姆(1967)以前提出的观点:如果深度和冷却系统都是适宜的话,一种典型的石英二长岩岩浆可以因冷却而产
INTRODUCTION In recent years, there is a deeper understanding of the theory behind the genesis of post-magmatic hydrothermal deposits, and Hollander (1972) summarized the number of base metal assignments between silicate melts and coexisting liquid phases The results of the study show that the amount of geologically suitable H 2 O and dissolved ferric chloride ions in a granulated melt can extract a sufficient amount of metal from the “normal” granulated melt to form a corresponding size Scale Later magmatism deposits Wittmann (1975) corroborates Burnham (1967)’s earlier argument that a typical quartz monzogranite magma can be produced from cooling if both depth and cooling systems are appropriate
