元岭金矿有原生破碎蚀变岩型和次生氧化淋滤型，产于熊耳群变火山岩中，受ＥＷ向和ＮＥ向断裂交汇处控制，硅化和黄铁绢英岩化有利矿化，原生矿是深部流体引起上覆陆壳岩石重熔、混合后，演化成成矿热液沿马超营断裂上侵并汲取围岩部分物质而成。
The Yuanling gold deposit is characterized by primary crustal alteration and secondary oxidation leaching. It is produced in the Xiong’er Group volcanic rock and is controlled by the junction of EW and NE fractures. Silicification and pyritization of pyritiferous ore are favorable. It is caused by the deep fluid remelting of overlying crustal rocks. After mixing, the ore-forming hydrothermal fluids have invaded along the Machaoying fault and draw some materials from the surrounding rocks.
