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

本矿床主要的赋矿地层为新太古界太华群高级变质岩。

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.

原岩形成于具有火山作用的活动大陆边缘滨海-浅海环境。经过太古宙的域高角闪岩相变质作用，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.

在龙岗地块与北的接触上，发育了一条晚太古宙-古元古宙时期的线活动。
