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.

明确黄孔兹岩系为一套变质富铝质沉积岩组合，在晋宁造山运间该套岩系经历四变质作用。

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.

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