金平白马寨铜镍硫化矿床杂岩体分带明显、属亚碱性铁质-超铁质岩、具Ni-Cu-Co三元素先熔离，后富集的规律、稀土配分为右倾斜轻稀土富集型，但橄榄岩铕亏损显著，Gd-Tb微小负异常，显示成矿物质来源地幔，与地壳物质无混染和大陆拉斑玄武岩浆上涌后变为大洋拉斑玄武岩浆侵位特点。

Based on major and trace elements and isotope geochemical data, it is inferred that Sandouding suite is formed by magma melting of Late Archeozoic continent tholeiite source, and its geochemical variation is controlled by hornblende fractional crystallization. Besides fractional crystallization, the geochemical variation of Huanglingmiao suite is related to the mixing between dacitic magma and felsic magma. Dalaoling suite is probably derived from early Precambrian volcanics.

根据岩石化学和同位素组成推断，三斗坪岩套的源岩主要是晚太古代大陆拉斑玄武岩，母岩浆相当于英安质，岩套内的成分变化主要受角闪石分离结晶作用控制；黄陵庙岩套除受分离结晶作用影响外，成分变化主要与英安质母岩浆和某种长英质岩浆的混合有关；大老岭岩套的源岩亦为早前寒武纪火山岩。
