河南省济源西部铁山河矿区深部成矿性分析

Analysis on the metallogenesis in the depth of Tieshanhe ore district in west Jiyuan,Henan province

在分析铁山河矿床成矿地质背景和矿床地质特征的基础上,根据铁山河矿区热液交代型铁矿的成矿规律和控矿地质特征,对铁山河矿区深部的赤山沟组成矿条件和找矿前景进行了分析:该组中下段有闪长岩体侵入,含有供热液交代的沉积岩层,而且处在构造有利部位,与已开采的白岩山组上段类似,理应具备有很好的成矿性.预测了可能成矿的深度和规模,提出了找矿思路.

Based on the analysis of ore - forming geological background and characteristics of Tieshanhc deposit, and according to the metallogenetic regularities and ore - controlling features of this hudrothermal metasomatic type iron deposit, the metallogenetic conditions and prospecting potential of Chishangou formation in the depth are analyzed. The results indicate that there has experienced diorite rock invasion in the lower formation and containing sedimentary layer that providing metasomatism layer, at the same time, it locates in the favorable location of structure on the similar with the mining Baiyanshan Formation. It has metallogenetic potential in the depth and the probable metallogenetic depth and scale and the prospecting direction in this area have been predicted.
