摘要
概括了豫西五丈山岩体南部主要含矿构造地质特征及分布格架。分析研究潭头—大章断陷盆地浅覆盖区地质特征及缓倾斜构造的展布特点。控矿因素中的火山机构受区域基底断裂控制,沿区域切壳深大断裂带呈串珠状分布,古火山机构构造对金矿床产出分布具有控制作用。成矿地质体—五丈山燕山期花岗岩体进入到造山期后的大规模伸展动力学背景之下,岩浆活动及其伴随形成的金矿床都必然受此构造背景控制。通过对该区缓倾斜赋矿构造及其成矿规律研究,认为本区缓倾斜含矿构造平行成组存在,根据近年勘查成果发现了缓倾斜构造蚀变岩型金矿床。这表明该区成矿地质条件较好,赋矿空间广阔。
In this paper,the geological characteristic of mineral-bearing structure and distributive framework of Wuzhangshan southern rock body are generalized,the geological feature of Tantou-Dazhang fault basin shallow coverage area and the distribution characteristics of the slow inclined structure are analyzed and researched,the ore-controlling factor-volcanic apparatus has the controlled function to the output of gold deposits,metallogenic geological body—Wuzhangshan Yanshanian granite body enters the period of large-scale extension dynamics after the orogenic period,magmatic activity and its accompanying gold deposits are inevitably controlled by this tectonic setting.By researching on the slowly inclined ore-hosting structure and metallogeny,the author thinks the slow inclined ore-hosting structure exists in parallel and group.According to the exploration achievements in recent years,the slow inclined tectonic altered rock gold deposit has been found.This shows that the ore-forming geological conditions in this area are good,and the ore-bearing space is wide.There are certain references to find the same deposit and prospect in the shallow overburden area in this regional.
