摘　　要：北山金矿区成矿地质条件十分有利 ,与华力西晚期陆相火山—潜火山作用有关的蚀变、矿化广泛发育。已有资料证明 ,矿区东部脉状蚀变岩型金矿化具有一定工业意义。近年来在矿区西部又发现了较大规模呈面型特征的物探高相位电性异常及叠加于其上的化探原生晕Au、As、Sb异常。初步的地质与物、化探综合评价工作证实 ,矿区西部具有寻找次火山斑岩型隐伏金矿的潜在远景。The metallogenetic geological condition in the Beishan gold mining area is very favorable. The alteration and mineralization associated with the late Variscan continental volcanic-subvolcanic process are widely developed. Available data show that the vein-like alteration-rock type gold mineralization in the eastern part of the mining area possesses determinate industrial significance. In recent years, planar high phase electric anomalies of geophysical exploration and superposed geochemical-prospecting primary halos of Au, As and Sb have been discovered in the western part of the mining area. Preliminary comprehensive assessments of geophysical and geochemical exploration show that potential prospecting of volcanic porphyry-type hidden gold deposits exists in the western part of the mining area.
