| 摘 要： | 以贵阳市大山洞岩-土剖面为例,通过对土层及其碳酸盐岩母岩在物质组分、结构构造等显微特征方面的研究,分析碳酸盐岩母岩的成土过程为:母岩在风化作用过程中,碳酸盐类矿物被溶解随水流走,难溶的粘土矿物和石英等残留下采,铝硅酸盐类矿物经分解并最终形成粘土矿物、褐铁矿、三水铝石、硬、软锰矿和蛋白石(最终变为玉髓和石英),上述矿物堆积下来形成土层。

| Abstract: | The Guiyang rock-soil profile at Dashandong is an example of carbonate rock weathering as described in the paper. The authors investigated soil and its mother rock (carbonate rock) in terms of their composition and structure, and considered that the soil-forming process of carbonate rocks is: carbonate minerals first dissolved in water, clay minerals and quartz were reserved, aluminum-silicate minerals were decomposed into clay minerals, limonite, bauxite, psilomelane, pyrolusite and opal (or chalcedony and quartz) in the process of carbonate rock weathering. The above minerals played on important role in soil formation. |
