中国红层的分布及地质环境特征

    THE DISTRIBUTES AND GEOLOGIC ENVIRONMENT CHARACTERISTICS OF RED BEDS IN CHINA

    • 摘要: 根据我国红层的分布特征及形成背景 ,将我国红层划分为西南地区红层、西北地区红层、中南、东南地区红层和其他地区 (西藏及华北的部分地区 )红层。重点研究了以川滇红层为代表的西南地区红层和以甘肃红层为代表的西北地区红层 ,研究了各个区域红层的地质构造特征、地形地貌特征、气候环境特征等工程地质环境特征 ,根据工程地质环境特征 ,将研究区域的红层划分为四川盆地红层、西昌滇中红层、滇西红层和甘肃红层.

       

      Abstract: Based on the distribution characteristics and formation background, a regionalization of red beds in China is suggested, such as red beds in northwest, southwest, southeast and south-central China and parts of Xizang and North China. The study was focussed on the red beds in Sichuan-Yunnan region, representative of southwest China and the red beds in Gansu, the representative of northwest China, the geologic environment characteristics of the red beds, such as the geostructural characteristics, geomorphic characteristics, climatic environment characteristics etc. were studied. According to the geologic environment characteristics, the red beds in Sichuan-Yunnan region are zoned into those in Sichuan basin, Xichang Dianzhong, Dianxi and Gansu.
