1·Bamboo stone for calcirudite by weathering and karstification and the formation of the stone.
竹叶石为砾屑灰岩经风化与岩溶作用而形成的块石。
2·The constructive diagenesis are mainly epigenic karstification and burial dissolution. The destructive diagenesis are filler in each periods, the most devastating cement to porous is sparry calcite.
其中建设性成岩作用主要是表生岩溶作用、埋藏溶解作用，破坏性成岩作用主要为各期的充填作用，对孔隙破坏性最大的胶结物是亮晶方解石。
3·The karstification had decided the red clay characteristic in the early time in soil forming process and the matter origin is different from soil types formed by other rock series;
岩溶作用决定了红粘土的成土早期和物质来源的特点不同于其它岩石形成的土类；
