甘肃省西和县四儿沟门金矿床地质特征及找矿前景分析

Geological Characteristics and Ore-search Prospect Analysis of the Siergoumen Gold Deposit in Gansu Xihe

通过对四儿沟门金矿床地质特征的分析研究,初步认为该矿床属于受构造破碎带控制的层控热水沉积-变质矿床。矿体产于中泥盆统西汉水组(D2X2-1)地层中,受层位和层间断裂破碎带控制,含矿岩石为石英脉、硅化灰岩和含铁方解石石英脉。基于以上的认识,分析了四儿沟门金矿的找矿前景,指出了找矿方向。

After a study on geological characteristics of the Siergoumen gold deposit, a preliminary conclnsion is made that the gold deposit is a strata-bound hydrothermal deposition-metamorphism deposit controlled by faulted fractures, ore bodies occur in the strata of Xihanshui group of middle-Devonian （ D2 x2＂1 ）, bound by stratohorizons and interlayer fissures, the ore-bearing rocks are quartz veins, silicated limestones, and ferriferous calcite-quartz veins, based on the above knowl- edge, ore-search prospect analysis of the Siergoumen gold deposit is made and the ore finding direction is given.
