玲珑金矿田山岔口金矿床地质特征及深部找矿潜力

Geological Characteristics and Deep Ore-exploration Potentiality of Shanchakou Gold Deposit in Linglong Gold Field

摘要:

山岔口金矿床位于玲珑金矿田北部。矿体受NE向断裂严格控制，主要呈脉状、透镜状产出，赋矿围岩为大庄子单元含斑粗中粒二长花岗岩。矿石为黄铁绢英岩化花岗质碎裂岩夹石英脉，矿石矿物主要为黄铁矿、黄铜矿、方铅矿、闪锌矿，金矿物主要为银金矿、自然金等。通过分析该矿床的矿体地质特征和空间分布规律，认为深部仍具有比较大的找矿潜力。

Abstract:

Shanchakou gold deposit locates in the north of Linglong gold field. The Ore body is strictly controlled by the faults with the trend of NE, and mainly occurred in veins and lens form. Ore-bearing country rocks are the porphyritic coarse medium grained adamellite in Dazhuangzi formation. Ores are fractured altered rock with quartz vein. Metallic minerals are mainly composed of pyrite, chalcopyrite, galena and sphalerite. Gold menerals are mainly electrum and native gold. Based on geological characteristics of ore bodies and spatial distribution rule, it is suggested that favorable prospecting potentiality can be expected in the deep part of this deposit.
