After that, the weatheringfront spread gradually and the rock block is turned into a saprolite block.
随着时间加长,风化前锋逐渐扩展,岩石结构体最终转化为腐岩结构体。

The weatheringfront is a main place of geochemical reaction, and at this limited-thick interface, with quick dissolution of carbonates, acid-insoluble residues begin to obviously decompose.
There are multiple sets of shear fissures and weathering fissures in the old landslide body with an effective freeing surface formed from the washed front.
