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。
通過介紹區域地質特徵和三角頂地區礦點特徵,分析區域內成礦條件,認為該地區礦床成因類型主要為“玲瓏式”石英脈型金礦床。目前,已髮現的紅燈溝金礦床、野駱駝泉金礦床、韆枚嶺金礦床等,均產自灘間山群地層中,而三角頂地區金主要產自彊蝕變的石英脈中,且在圍巖-花崗閃長巖中採取高品位化學樣,推測花崗巖閃長巖中具有尋找大型金礦的潛力。

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 pres-ent, 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 specu-lated the potential to find big gold .
