| 摘 要： | 研究了区域金的地球化学特征，白际岭地区上溪群浅变质岩同江西双桥山群浅变质岩有着类似的有利金富集成矿的层位；燕山期酸性岩体也有利于金成矿；金的区域地球化学场分布受断裂构造、地层及岩浆岩控制．与金共生的异常组合存在5种类型，其中以Au-As-Sb，As-Pb-Zn-Au-Ag-Sb多元素组合为区内最主要成矿元素组合；已知金矿化(点)的地质地球化学特征均类同于金山金矿，为韧性剪切带型金矿，以Au-Sb-As等为主的异常元素组合为该类型金矿的指示元素，在本区寻找韧性剪切带型金矿具有良好的前景．

| Abstract: | After the analysis of the regional gold geochemical characters, it is considered that the low-grade metamorphic rock of Shangxi Group in Baijilin area has the favorable gold ore-forming layers, which is similar to that of Shuangqiaoshan Group of Jiangxi Province. The acid intrusive rock of Yanshan Period benefits the formation of gold deposits. The distribution of the regional geochemical field of gold is controlled by fault structure, stratum and intrusive rocks. There are 5 types of the co-existing anomaly combinations, in which Au-As-Sb and As-Pb-Zn-Au-Ag-Sb are the main multi-element combinations in the area. The geochemical characters of the mineralization sites known are similar to the Jinshan Gold Mine. They belong to the gold deposits of the ductile shear zone type and are characterized by the Au-Sb-As combination as indicator elements. It presents a good perspective to explore gold deposits of the ductile shear zone type in this region. |
