河南熊耳山地区铜矿找矿前景分析

ANALYSIS FOR EXPLORATION PROSPECTING OF COPPER ORE IN THE XIONG'ERSHAN GEODOME OF HENAN PROVINCE

以壳体成矿学理论为指导,据地质、地球物理、地球化学和遥感等资料,对河南熊耳山地穹铜矿找矿前景进行成矿学分析。该地穹东段、西段为铜矿成矿的有利地区。东段铜矿以和金矿共生为主,西段铜矿则以独立矿床为主,金银为伴生元素,为铜矿成矿最有利的地区。其中寨凹地区在大地构造背景、控矿构造、成矿母岩、成矿元素分带、蚀变特征、地球物理、地球化学和遥感信息特征等方面对形成斑岩型铜矿非常有利,为斑岩型铜矿的成矿远景区。外围的脉型铜(银)矿、银多金属矿也有较大的资源潜力。

Guided by the crust-body metallogeny and based on data of geology, geophysics, geochemistry and remote sensing, a metallogenic analysis for copper exploration prospecting in the Xiong'ershan geodome of Henan province has been discussed. It is concluded that east and west parts of the geodome are favorable area for copper deposit formation. Copper shows as a paragenetic component with gold in the east part, and exists as independent ore in the west part with gold and silver being associated elements. Based on tectonic background, ore-controlling structures, ore-forming mother rocks, ore-forming elements zoning, alterations, geophysics, geochemistry and remote sensing, Zhaiwa area is a favorable region for formation of porphyry cupper deposits, and also prospective region for porphyry copper deposits. Vein-type copper (silver) deposit, silver and multi-metal deposits in the periphery have larger resource potential.
