摘　　要：以吉林省白山地区金矿产为预测矿种,以金矿床为目标物,在前人对该地区地质研究成果的基础上,系统分析了地层、岩浆岩和构造等地质条件与金矿产的关系,查明了各种地质条件对金矿产的控制作用。同时利用地质、化探和物探等相关数据,对该地区进行了金成矿综合信息矿产预测,建立了以中元古代地层为主要成矿地层,北东向和北西向断裂为主要控矿构造,航磁解译环形构造和重力高背景场为主要成矿标志,以及化探元素呈现三种组合异常等因素的吉林白山地区综合信息找矿模型。The authors analyzed the relationship between gold mine and geological conditions including strata,magmatic rocks,structure,etc.and identified the control action of various geological conditions to gold mine base on previous research results and taking the gold mine in Baishan area of Jilin as the prediction mine type and the gold deposit as the target.At the same time,the sythetic information ore-prospecting of gold mine has been forecasted in this area by geological,geochemical and geophysical data,and the authors have established the sythetic information ore-prospecting model in Baishan area of Jilin with Middle Proterozoic strata as the main ore-forming strata,the NE and NW trending faults as the main ore-controlling structures,and the aeromagnetic interpretation circular structure and gravity high background field as the main ore-forming signs with geochemical elements demonstrate three types of combination anomaly.
