个旧矿区高峰山矿段花岗岩突起地质特征及找矿分析

THE GEOLOGICAL FEATURE AND PROSPECTING ANALYSIS OF PROJECTING GRANITE OF GAOFENGSHAN ORE BLOCK IN GEJIU OREFIELD

云南个旧锡多金属矿田随着近年地表矿、浅部矿及易识别矿体的大量开采,资源也越来越少,因此地质找矿必须转向深部矿及隐伏矿。本文通过对高松矿田高峰山矿段花岗岩岩脊的空间形态、含矿特征、控矿因素系统分析,探讨控矿规律及成矿机制,为找矿提供理论依据。综合研究认为高峰山矿段1#-6#花岗岩次级突起顶端是有利的成矿空间,特别是不同方向构造交汇处和地层互层剥离处是花岗岩入侵的有利部位及矿体赋存的有利场所。

To Gejiu Sn multimetallic orefield the resources are more and more decreased because of enormous exploitation of surface, shallow and recognizable orebody.Therefore, the geological work needs prospecting toward the deep and buried deposit.In this paper, we according to the systemical analysis of the space form, ore-bearing feature, ore control factor of granite rock ridge of Gaofengshan ore block in Gaosong orefield, have a probe into the ore control rule and metallogenesis mechanism, provide theoretical fountain for prospecting.According to the comprehensive study, we think the 1#-6# granite secondary projecting top is the advantageous metallogenesis space, specially, the intersection area of different direction structure and debonding of strata alternating is the advantageous part of granite intrusion and advantageous area of orebody exist。
