吉林通化南岔式金矿地质—地球物理—地球化学综合找矿模型

Integrated geological-geophysical-geochemical ore prospecting model of the Nancha-style gold deposit in Tonghua,Jilin

老岭成矿带为吉林省最重要的贵金属、有色金属成矿带,南岔金矿是该成矿带近几年新发现的金矿床。在阐述南岔金矿成矿地质条件、岩(矿)石物性参数特征、地球物理场、地球化学特征的基础上,归纳并提取了控矿地质因素和物化探找矿标志,从而建立了“南岔式”金矿的地质—地球物理—地球化学找矿模型。

The Laoling metallogenic belt is the most important noble metal and nonferrous metal metallogenic belt in Jilin Province and the Nancha gold deposit is a gold deposit found in recent years in this metallogenic belt.On the basis of studies of the metallogenic-geological conditions ,rock(ore)physical parameters,geophysical field and geochemical characteristics of the Nancha gold deposit,the author has summarized and extracted the ore-control ling fac-tors and geophysical and geochemical ore guides and constructed a geological-geo physical-geo-chemical ore-prospecting model of Nancha-style gold deposits.
