玲南金矿的成矿特征及断裂控矿规律研究

在对玲南金矿床的成矿特征、控矿构造、矿化及蚀变产物综合分析的基础上,论述和总结了矿床地质特征、破头青断裂带特征及其对成矿的主导控制作用。认为矿化和蚀变产物的形成在时间上相近、空间上叠加;它们是同一成矿作用的两个有机组成部分,是矿床成矿演化历史的实物记载;成矿期断裂的多次活动及第Ⅱ、Ⅲ阶段矿化的叠加发育,分别为玲南特大型蚀变岩型金矿成矿的必要条件和充分条件。

A STUDY OF THE METALLOGENIC CHARACTERISTICS AND FAULT -CONTROLLED REGULATION IN LINGNAN GOLD DEPOSIT , SHANDONG PROVINCE

Based on the study of the metallogenic characteristics and the time-spatial relationship between the products oftectonization and mineralization in Lingnan gold deposit ,the characters of Puotouqing iault - zone and its controlling process over the metallogenesis are discussed and summarized in this paper . The products of mineralization and alteration occurred at similar time and spatially superposed each other , which are not only the geological records of metallogenic history ,but also the two parts of the mineralization .The occurrence of metallogenic faults and the superposition and development of the second and third metallizing phase are , respectively , the neccessary and sufficient conditions for large and super-large scale gold deposits forming Lingnan-like gold deposit .
