Spatial Distribution and Its Genesis of the Danxia Landforms in Xinjiang Basin, Jiangxi Province
详细信息   
摘要


     Xinjiang Basin is one of the most typical and concentrated sites of danxia landform distribution in China. Dued to constraints of genesis system including red beds, structures and exogenic geological process that controlled evolution of it, the danxia landforms in different parts of Xinjiang Basin have undergone different evolutionary processes and formed different landscape assembly. In the margins ~f the basin there are exposed very thick bedded rocks including conglomerate, pebbly sandstone and sandstone of Maodian, Hekou and Lianhe formation, the ce- ments are mainly ferric and a small amount of calcareous and the content of the soluble ingredient is low. There de- veloped high cliffs and the Danxia Landforms are characteristic with hoodoos and peak clusters with a tilted top. In the middle of the basin there are exposed the upper of Hekou formation and Tangbian formation along the banks of Xinjiang River, the rocks are compose of thick or huge thick bedded sandsto,e and pebbly sandstone with large cross bedding, calcitic cement and the content of the soluble ingredient is low, in where have developed lower cliffs with round tops and the typical landscape were big stone caves along the banks. Between the margin and middle, there exposed mainly sandstone of the upper of Hekou formation, Tangbian and the lower of Lianhe formation that developed mesa, narrow valley, stone cliffs with flat top.
