Abstract: The geological vestiges are nonrenewable natural legacy, which are formed by endogenic and exogenic process. The important vestiges are not only the national valuable treasures, but also the necessary components of the ecological environment China is one of the minority countries, which rich in category, distribution and quantity of the geological vestiges. The Hukou fall, one of the biggest falls, is special in the corrosive and hiding in yellow fall, and rare in the world. It lies in the south edge of the North China plate and the southeast of the Ordos platform. Its basement is composed of Archaeozoic metamorphic rock.The Zhifang Group(T_2z)and the Tongchuan Group(T_2t)of the Triassic system strata emerge in Jinshaan gorge,its occurrence is nearly horizontal(the dip angel 3°～5°). The tectonic movement is mainly massive rise and fall,and the strata fold slightly.
