论碳酸盐岩现代风化壳和古风化壳

从地质学关于风化作用的基本原理和观点出发,结合作者以往的研究成果,进一步论述了碳酸盐岩现代和古风化壳形成和基本特征问题; 运用“将今论古”地质学基本方法,应用作者关于溶蚀- 交代由基岩到土体等体积成土作用的理论,解决了100多年以来铝土矿地质学家一直争论不休的钙红土成因的铝土矿的物源问题;研究指出,碳酸盐岩风化壳是一种耗散结构系统,组成该系统的各单元构成一个整体、且具有不可替代的功能和作用; 作者特别强调了水- 岩、岩- 土界面上溶滤层的关键作用,据此从成因上解释了红粘土为何具有高孔隙(孔隙度、孔隙比)特性。 

ON MODERN WEATHERING CRUST AND PALAEO-WEATHERING CRUST OF CARBONATE ROCK

According to the geological principles of weathering process and combining with results of the authors' research, the formation and characteristics of the modern and palaeo-weathering crusts of carbonate rock have being further discussed. According to the basic geologic principle of "understanding ancient according to present situation" and applying the authors' theory about genesis of laterite, the difficult problem about the formation of calcareous red clay is resolved. The problem has confused geologists for a hundred years. Weathering crust of carbonate rock is a dissipative structure system. Every unit of the system is absolutely necessary for weathering process. The authors especially emphasize the key effect of the leaching layer on the boundaries between water and rock, and between rock and soil. It is just this layer that caused the laterite being of the highest porosity among all kinds of clay.
