| 摘 要： | 衡山南岳岩体北侧,地质构造复杂,岩浆活动频繁,金矿成矿地质条件有利,已发现一个具有远景的金矿带,其中石子坳矿区为构造蚀变岩型金矿。本文简要地介绍了区域和矿区地质特征,总结出花岗闪长斑岩,硅化带和As元素化探异常等3条找矿标志,建议在该区开展大比例尺化探测量和地质填图,普查北西向硅化断裂破碎带,并对石子坳含金破碎带进行深部验证,寻找隐伏金矿床。

| Abstract: | The north side of Nanyue rock mass in Hengshan is of complicated geologic strcuture and frequent magmatic activities, which made up the favourite oreforming geologic condition for gold mineralization, where a promising gold ore belt has been discovered,of which Shiziao ore district is tectonic alteration rock type gold deposit. A brief introduction is made to the geologic feature of the mine and region, and it is summed up that the granodiorte, silicified zone and geochemical anomaly of As are three prospectng criteria. It is suggested to conduct large scale geochemical survey and geologic mapping, to make reconnaissance survey of the north--west orientated silicified fault fracture zone, and to carry ont verification to the deep part of Shiziao gold-bearing fracture zone, so as to find the concealed gold orebodies. |
