Shagou deposit mainly lies in the metamorphic rock of Taihua Group,Archaeozoic erathem.

本矿床主要赋矿地层为新太古界太华群级变质岩。

Its original rock is sedimented in the environment of active epicontinent-seaboard with basic volcanism, and become khondalite series through the Archean regional high-amphibolite facies metamorphism.

原岩形成于具有基性火山作用活动大陆边缘滨海-浅海环境。经过太古角闪岩相变质作用，形成孔兹岩系。

To date, komatiites with spinifex textures have not been found in the supracrustal rocks, but rock sequences similar to greenstones metamorphosed up to upper amphibolite facies are often observed.

在龙岗地块与北带之间接触带上，发育了一条晚太古-古元古时期线性活动带。
