Analysis on infrared spectra characteristic of coal and discussion of coalification mechanism

There exist some limitations in the traditional coalification theory such as the arorntization and ring-condensation, and the rnaking-up action of the basic structural units (BSU) incoals mny be a peculiar mechanism for the developmnt of high-rank coalification.

The results of EASY%Ro numerical simulation about coal evolution history and coalification process of Upper Paleozoic in Southem Shanxi have been reported in this paper after introducing it's theory.

Research evolution and development direction in the early diagenesis;

According to the depositing course of carbonate, sulphate and halide in the surface of soil, we can systematicly study on the migration path, migrational pattern, crystallisation and accumulation, cementation, metasomasis, later leaching and solution of salts by early diagenesis.
