The strata formed karst in North China is mainly composed of Majiagou Formation in Ordovician and dolomite with siliceous bands of Wumishan Formation, Jixian System in Middle Proterozoic. The local Fangshan landform is made up of Pliocene stone forest on mountain top and Quaternary karst stone cliffs, all formed within Wumishan Formation. There is Fangshan granodiorite between Shihua Cave system and another Karst Cave system of Peking Man Site at Zhoukoudian. Eight altitude levels of Shihua Cave system represent corresponding times of the neotectonic movement in Beijing Western Hills. It may correlate with physiographic stages of North China and terraces of Yongding River.
