摘　　要：对胶东金牛山金矿区金矿深部地球化学原生晕研究,结果表明金牛山金矿区金牛山矿段地球化学轴向分带具有反向分带特点,亦有正向分带的存在,原生晕复杂,为原生叠加晕,有不同原生晕共存和反向分带现象存在。据此推测50勘探线西主脉和中主脉分别在-50m和+15m以下有较大延伸,而54勘探线东副脉在0m以下可能有盲矿体存在。Studies on deep geochemistry primary halo of Jinniushan gold deposit in Jiaodong showed that the primary halo of the west main ore vein at 50 line has characteristics of reversed axial zoning sequence, and that the middle main ore vein at 50 line and the east second ore vein at 74 line have characteristics of axial zoning. Therefore, It is considered that underlying port of the west and middle main ore vein at 50 line are deep in -50m and +15m, the east second ore vein at 54 line are possibly superposed by a blind ore-body in deep position.
