DISCUSSIONS ON THE WEATHERING CRUST FORMATION,PALAEOWEATHERING CRUST FORMATION AND THEIR GENERATION MECHANISM

The weathering crust materials resulted from modern processes are migrated and emplaced to form the weathering crust formations,whereas the palaeoweathering crust materials resulted from ancient weathering processes before the Quaternary were migrated and emplaced to form the palae-oweathering crust formations. These distinct formations generally differ from the marine and conti-nental sediments but also have nothing to do with plate tectonics;nevertheless,as a kind of distinc-tive formations,they are well worth discussing in view of their similarity in generation mechanism, weathered mineral,texture and structure,migration and emplacement mechanism as well as the het-erogeneity in grain size and random arrangement of grains.
