摘　　要：本文以何宝山矿段为典型实例，较系统地论述了矿区主要控矿构造地球化学特征，探讨了矿区原生晕指示元素分带序列和金矿化剥蚀程度。认为矿区主矿带何宝山矿段Ⅱ号矿化带南北两段产状及剥蚀程度的差异，系受东百向张扭性断裂（Ｆ５）成矿后活动影响所致。This paper focuses on the geochemical characteristics of major ore-controlling structures, zoning sequence of indicator elements from the primary halo and denudation in the Hebaoshan Gold Ores. The Hebaoshan Gold Ores is situated at the intersection point of the Chongan-Shicheng Structural Belt and Jianning-Jianou Structural Belt in Fujian Province. Take the Hebaoshan ore block as an example, which is the major ore belt of the Hebaoshan Gold Ores. It is concluded that the difference of occurrence and denudation between the southern and northern ore blocks in the No. 2 mineralizational belt of the Hebaoshan ore block results from the tensomshear fault of the EW trend.
