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.

明确黄陵地区孔兹岩系为一套质的富铝质沉积岩，晋宁造山运动间该套岩系经历质作用。

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.

原岩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角闪岩相质作用，形成孔兹岩系。
