摘要
胶东地区是我国著名的金矿集中区,金矿主要受胶西北3条"S"形断裂带控制,自西向东分别为三山岛、焦家、招平断裂。其中,招平断裂带为胶东地区重要的金成矿带之一,目前该成矿带内已探明金储量800 t,成矿潜力巨大。莱西市山后金矿区位于夏甸大型金矿床以南,旧店金矿田的北部,招平断裂带的中南段,由山后、北泊、萌山3个矿段组成。随着招平成矿带研究和控制程度的不断增高,显示该区成矿潜力较大。但是,对其成矿规律的研究仅局限于夏甸金矿床以北,对以南地区金成矿规律的研究力度不够。我们从构造应力场方面分析了该区段金成矿地质条件,并对该区成矿远景进行了评价。
Jiaodong is the famous gold-concentrated area, gold mainly is controlled by three ＂S＂-type fault belt, from west to east, respectively Sanshandao, Jiaojia and Zhaoping faults. Zhaoping fault zone is one of the most important gold faults, it has already been proven gold reserves of 800 tons, and the ore-forming potential is great. Shanhou gold deposit is located in Laixi, south of Xiadian gold deposit, north of Jiudian gold deposit, middle-south of Zhaoping fault belt, it is composed of three mining sections, respectively Shanhou, Beibo and Mengshan. With increasing of study and control degree of Zhaoping metallogenic belt,indicating the mineralization potential of this area is great. However, research of metallogenic regularity in this area is limited in north of Xiadian gold deposit,the research extent of southern parts is very low. We analyse the geological conditions of gold mineralization by tectonic stress field, and evaluate the ore prospecting of this area.
