Characteristics and genesis of red karst in Guizhou section of Youshui river basin
-
摘要: 在酉水流域贵州段及其周围存在一套特殊的以红色为主、白色为辅、外观形态凹凸有序的独特岩溶地貌。文章将该类地貌命名为“红色岩溶”,并调查了研究区红色岩溶的分布范围、颜色特征、形态特征。通过地表水体pH、土壤pH和CO2溶度测试及岩石薄片鉴定,分析了红色岩溶塑形作用力及塑性环境。进一步,总结分析了红色岩溶的成因条件及成因过程。Abstract: A special set of karst landforms is present in and around the Guizhou section of the Youshui river basin. Its color is mainly red,followed white, with shape of concave-convex. This article names this type of landforms "red karst" and examines the distribution,color characteristics,and morphological features of red karst in this area. The forming force and environment of red karst are analyzed by testing the surface water pH,and CO2 content in soils and identifying rock flakes. Furthermore, the generation conditions and processes of red karst are summarized and analyzed in the paper.
