我国红色岩层及其侵蚀性地下水

我国红层主要分布于长江流域及其以南地区。根据红层发育的地质年代和含膏盐岩层层位不同,可分为西南地区和华南地区红层。根据红层中含可溶盐类矿物的不同,又可分为含膏红层与含盐红层。两种含不同盐类的红层,其地下水化学性质和侵蚀性离子浓度的频率分布特征有明显差别。确定两种含盐红层的侵蚀性离子浓度的频率分布规律,为预测和评价类似地质环境条件下地下水成分特征提供了有意义的参考资料

The Red Beds and Their Corrosive Groundwater in South China

The red terrigenous sedimentary layers that are shortly called as red beds are extensively distributed in South China. Basins of various size are made up of them. on the basis of geological age and the horizon of saline-bearing layers, the red beds may be divided into two large regions-Southwestern region and Southeastern region. Based on the kinds of saline-bearing and composition of groundwater, they may also be divided into two types-gypsum-bearing red beds and composite saline-bearing red beds. According to the statistical analysis of the corrosive water of red beds and the frequency distribution of ion contents in groundwater, the Author tries to forecast the varying law of main ion contents in the similar geological conditions.
