混合溶蚀作用最早是由前苏联学者布涅耶夫于1912年发现。岩溶水的混合溶蚀作用包括饱和溶液的混合溶蚀、外来物质的混合溶蚀、以及温度混合溶蚀等三个方面。一般地,两种方解石浓度不等的水混合后,会降低方解石的饱和度或重新对方解石具有侵蚀性。 滨海岩溶区过渡带的水化学特征,主要是NaCl型的海水同淡水的混合,从岩溶角度来看,也可以说是方解石过饱和的海水同方解石呈平衡状态的淡水的混合——微咸水,随着发生混合溶蚀作用,在滨海岩溶区发育各种岩溶现象。滨海岩溶具有与内陆一般岩溶区所不同的发育机理,其过渡带混合溶蚀作用是控制滨海岩溶发育的最主要影响因素之一,这从实践中已经得到了证明。但对我国滨海古老碳酸盐岩岩溶区过渡带混合溶蚀作用的研究还相对较少;而且,由于混
Mixed erosion was first discovered by the former Soviet scholar Bieyev in 1912. The mixed dissolution of karst water includes the mixed solution of saturated solution, the mixed dissolution of foreign matter, and the temperature of the mixed erosion of three aspects. In general, mixing two types of water with different concentrations of calcite may reduce the degree of calcite saturation or re-calcite calcite. The hydrochemistry of the transitional zone in the coastal karst region is mainly a mixture of NaCl-type seawater and freshwater. From a karst point of view, it can be said that the seawater with supersaturated calcite is mixed with the fresh water in which calcite is in an equilibrium state - brackish water , With the occurrence of mixed erosion, a variety of karst phenomena are developed in the coastal karst area. Coastal karst has different development mechanism from inland karst area, and the mixed dissolution of transitional zone is one of the most important factors controlling the development of coastal karst, which has been proved in practice. However, there are relatively few studies on the mixed dissolution of the transitional zone of the ancient carbonate rocks in the coastal area of China. Moreover,
