甘肃省合作市以地南铜金矿矿床成因及找矿标志

Genesis and prospecting criteria of copper and gold deposits in the south of Hezuo City, Gansu Province

本文确定成矿有利区段及主矿体资源潜力,对以地南矿区铜金矿开展补充详查,基本查明矿区地层、构造、岩浆岩等地质特征及其与成矿的时空关系,控矿因素与矿化富集规律及找矿标志;工作区矿体数目、赋存部位、顶底板岩性,矿石矿物、脉石矿物种类及含量等对矿床开发经济意义进行概略研究。

In this paper, the favorable metallogenic section and the resource potential of the main ore body are determined,and the supplementary detailed survey of copper and gold deposits in the mining area in the south of the earth is carried out to basically find out the geological characteristics of the mining area, such as strata, structures, magmatic rocks and their temporal and spatial relationship with mineralization, ore controlling factors, mineralization enrichment laws and prospecting indicators;The number of ore bodies, occurrence location, lithology of roof and floor, types and contents of ore minerals and gangue minerals in the working area have a general study on the economic significance of deposit development.
