amphibolite

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.

在龙岗地块与北之间的接触上，发育了一条晚太古宙-古元古宙时期的线性活动。

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.

原形成于具有基性火山作用的活动大陆边缘滨海-浅海环境。经过太古宙的区域高相变质作用，形成孔兹系。
