试论大型、超大型金矿金质来源的途径——以吉林和山东地区金矿为例

STUDIES ON THE GOLD ORIGINATING WAYS OF LARGE-SUPER LARGE GOLD DEPOSITS

通过对吉林夹皮沟及山东上庄等金矿床成矿地质条件、循环流体、构造机制及高温、压模拟实验的分析，指出金质并非由某一地质时期的地质作用所产生，而是构造成矿系统的产物；金质并非直接来自某一类岩性，而是源于多层次循环流体对多类型围岩的萃取、勾通和混合；金质并不单纯取决于成岩成矿和物理化学作用，而是多层多类型构造机制数次应力作用的综合结果。

By the analysis of ore-forming geological condition, liquid circulation, structure mechanism and model experiment of high temperature and high pressure of Jiapigou gold deposit in Jilin province and Xiazhuang gold deposit in Shandong province, it is said that the gold was not formed by a certain geological action in a certain geological period, but the product of a system of structure and ore-forming; the gold was not directly from a certain type of rock, but originated from extraction, connection and mixture which took place, between multi-grade liquid circulation and multi-type countryrocks, the gold was not simply controlled by geophysical and geochemical actions, but the comprehensive action result ot the stresses which were multi-grade and multi-type structural mechanism.
