khondalite

The khondalite lithology is composed of a suit of metamorphic aluminium-sedimentary rock.During the Jinning movement, the sedmentary rock experienced four stages of metamorphism.

明确黄陵地孔兹系为一套变质质沉积组合，在晋宁期造山运动期间该套系经历四期变质作用。

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活动大陆边缘滨海-浅海环境。经过太古宙高角闪相变质作用，形成孔兹系。
