Environmental issue has caused widely public concern. In this thesis, the mechanism of calcite cluster structure absorbing environmental infectant has been investigated using quantum chemistry calculation. Using B3LYP calculation method and taking 6-311++G (3df,2pd) basis set in our Gaussian calculations, the results show that the calcite cluster structure can absorb environmental infectant.

The authors have summarized relevant data studied by overseas scientists and suggested the definition of chalky texture formation as "Chalky texture formation refers to that magnesium calcite and aragonite are transformed into the framework of micrite and microspar of low-magnesium calcite via neomorphism, and result in and maintain intercrystalline pore and throat networks in it; enhanced chalky texture formation refers to that the micrite and microspar are successively subjected to dissolution and leaching, so that the secondary network of solution voids is formed".

The paper expatiated the physical characters and mechanical performances of the composite material slabs synthesized by one, two, three or four minerals namely mica, mica + calcite, mica+ pyrophyllite + calcite or mica + calcite + pyrophyllite + periclase. It is concluded that the quality of the composite material consist of multiple minerals is better than the single material.

Two dominate variation trends are distinguished in the data plots of compressional-wave velocity versus Possion ratio, indicating the effects of mud content and calcite cement on the elastic properties of sandstone samples. In each change trend, with the rock texture transfering gradually from grain-supporting to matrix-supporting with increasing mud and calcite cement content, the propagation of elastic wave also changed from grain-to-grain contacts to rock matrix, which resulted in the measured data illustrating extremely different tendency. It helps utilize the physics properties of reservoir sandstone to extract rock texture and diagenesis properties in the research area.
