Analysis on the Geomorphic Type Characteristics and Genetic Evolution of Danxia in Tongde Shizang, Qinghai

The Danxia landform landscape with the largest contiguous area and typical morphological characteristics in the upper reaches of the Yellow River Basin is developed in Shizang area of Tongde, Qinghai Province. Based on the field investigation and comprehensive analysis, the Shizang Danxia landform was classified according to the individual landform form, including 7 Danxia positive landform and 5 Danxia negative landform, with diverse types and unique landscape. The Shizang Danxia landform in the formation of paleogene Xining group purple thick layer glutenite, affected by geological structure, physical and chemical weathering, erosion, and gravity machinery, such as the inside and outside sales force shape formation, and go through the red layer accumulation, red basin tectonic uplift, danxia landforms of infancy and adolescence formed four evolutionary stages. It is of theoretical and practical significance to further understand the development of Danxia landform in western China, popularize the knowledge of earth science, and protect and utilize the geoscience tourism resources.
