摘要
金青顶、三甲、英格庄金矿位于胶东隆起区东部的牟平—文登隆起南缘,牟平—乳山金成矿带的中部。区域内NNE向断裂最为发育,为金矿热液的富集成矿提供了有利的赋存空间。牟乳矿带金矿床多数产在昆嵛山花岗岩与胶东群变质岩接触带的花岗岩一侧,体现了时、空、岩控矿特点。牟乳地区可以划分出4个NW向构造条带,其中只有金牛山—金青顶成矿带、午极—三甲成矿带是较强的构造成矿带,而其他2个带成矿较弱、岩脉不发育、极少出现工业矿床。从成矿地质条件、矿床地质特征、矿床成因、金矿富集规律等入手,分析矿床的控矿因素,提出新的找矿方向。
Jinqingding, Sanjia, Yinggezhuang gold deposit is located in Muping-Wendeng from the southern edge of the text of the eastern part of the Jiaodong, the central of Muping-Rushan metallogenic belt. NNE fracture in this region develops mostly, provides an advantaged occurrence for the enrichment and mineralization of gold hydrothermal. Mu-Ru gold metallogenic belt lays on a side of granite which is on the contact belt of granite in Kunyu mountain and metamorphic rock in Jiaodong group, reflects the ore-controlling characteristics of the time, space and ore-controlling characteristics of rocks. Muping-Rushan metallogenic belt of the region can be divided into four tectonic NW bands, of which only Jinniushan-Jinqingding metallogenic belt, the Sanjia metallogenic belt is relatively strong tectonic metallogenic belt, while the other two with more mineralization weak, non-dyke development, very little industrial mineral deposits. Beginning with metallogenic geological condition , geological characteristics of ore-bed , ore-forming , laws of gold enrichment , we analyse the ore-controlling factors , and put out a new prospecting direction.
