| 摘 要： | 尖宝山金矿床受冀东幔枝构造的北缘拆离带和喜峰口－凌源NE向断裂带的控制，矿区形成3个较大规模的金矿化带。研究认为拉马沟组变质岩石基底富矿源岩（层），元古界长城系中的金元素亦参与了成矿。北矿化带形成于韧脆性构造环境，而南矿化带则始于韧脆性环境，终于脆性环境。矿床成因为在拆离带型金矿化上叠加了构造蚀变岩型金矿化。

| Abstract: | Jianbaoshan gold deposit is controled by detachment zone and NE trending Xifeng Kou Lingyuan fractural zone at the north margin of the Jidong mantle plume branch. There are 3 major mineralization zones in the mine area. Archean metamorphic rock of Lamagou formation is the basal source rock of the deposit. Gold in Proterozoic rock of changcheng series was also incorperated in the ore formation. The north mineralization zone was formed under ductile britlle enviorenment; the south mineralization zone began with the ductile britlle enviorenment and terminated at the brittle. And overprint of altered rock type gold mineralization on detachment type gold minesalization resulted in formation the deposit. |
