山东蓬莱初格庄北金矿地质特征及找矿方向

Geological Characteristics and Ore Prospecting Direction of Chugezhuangbei Gold Deposit in Penglai City of Shandong Province

初格庄北金矿位于栖霞-蓬莱金成矿带,成因类型为中低温热液石英脉-蚀变岩复合型。矿体受NNE—NE向断裂严格控制,呈脉状、透镜状平行斜列式产出;矿石矿物主要为黄铁矿、银金矿、自然金等。该文通过对该矿床地质特征、控矿因素的研究,在分析找矿标志的基础上,提出应加大深部找矿的建议。

Chugezhuangbei gold deposit locates in Qixia -Penglai gold ore belt .Its origin belongs to medium-low temperature quartz vein-altered rock composite type .The Ore body is strictly controlled by faults with the trend of NNE-NE, and occurred in veins and lens with parallel oblique column form .Metallic minerals are mostly com-posed of pyrite , electrum and native gold .According to study on geological characteristics and ore -controlling fac-tors, on the basis of analyzing ore prospecting symbol , suggestions are put forward to strengthen ore exploration in deep part of the gold deposit .
