摘要
区域地球化学场形成和发展演化与地壳发展演化阶段物质组成关系密切，这种关系体现在区域地壳物质组成的差异性，决定了区域地球化学场的性质和结构，地球化学金属省是区域地球化学结构的组成部分。研究结果表明：吉林省可以划分出五个与区域成矿作用关系密切的地球化学金属省，为区域成矿预测、普查找矿、远景规划、靶区选择等提供地球化学依据。
The formation of regional geochemical field and its evolution have close relation with thematerial components in evolutional stage of the earth crust,which incarnctes the differenceof regional crust material components and determines property and structure of regional geo-chemical field.The geochemical metallic province is a part of regional geochemical structure.Through the research,it is indicated that 5 geochemical metallic provinces closely related toregional mineralization can be divided in Jilin province,meanwhile,we propose geochemicalbasis for regional metallogenic prognosis,searching for mineral deposits, prospective planning,selecting target areas and so on.
