山东蓬莱初格庄北金矿地质特征及找矿方向

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

摘要:

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。

Abstract:

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 composed of pyrite, electrum and native gold. According to study on geological characteristics and ore-controlling factors, on the basis of analyzing ore prospecting symbol, suggestions are put forward to strengthen ore exploration in deep part of the gold deposit.
