摘要
通过介绍区域地质特征和三角顶地区矿点特征,分析区域内成矿条件,认为该地区矿床成因类型主要为"玲珑式"石英脉型金矿床。目前,已发现的红灯沟金矿床、野骆驼泉金矿床、千枚岭金矿床等,均产自滩间山群地层中,而三角顶地区金主要产自强蚀变的石英脉中,且在围岩-花岗闪长岩中采取高品位化学样,推测花岗岩闪长岩中具有寻找大型金矿的潜力。
By introducing the regional geological features and San Jiaoding area mines,regional metallogenic conditions was analyzed,and the region deposit genetic types are thought mainly ＂ Ling Long type＂ quartz vein type gold deposit. At present,the Hongdenggou gold deposit,Yeluotuoquan gold deposit,Qianmeiling gold deposit,etc.,has been found,all in the formation of Tanjianshan group. Whereas Sanjiaoding region vein gold was mainly hosted in quartz with strong alteration.The high grade chemical sample were collected in the surrounding rock-granodiorite,granodiorite and that rock has speculated the potential to find big gold.
