摘要
本文对吉林省南楼山中生代火山洼地所处地质环境,重力、航磁场特征环境,水系地球化学异常的相关性进行了综合研究。文章指出,南楼山火山洼地物化探异常之间相关性突出,与所处构造=火山岩条件关系密切。后期岩浆侵入与洼地早期火山岩相互作用,主要体现了铁、铜族元素的成矿机制。
The geological environment, gravity and aeromagnetic field characteristics and correlation of water system with geochemical anomalies of Nanloushan Mesozoic volcanic depressions in Jilin Province are comprehensively studied. The author pointed out that there has obvious correlation between geophysical and geochemical anomaly of Nanloushan volcano depression, and has closely relationship with the volcano rocks structures. Late magmatic intrusion and the early volcanic rock of depression interacted, mainly reflected the the metallogenic mechanism of iron and copper group elements.
