Abstract:
Phosphorite ore deposits are widely distributed in South China. They have been found in almost every system through the geological ages. But about 70% of the industrial phosphate deposits are accumulated in the Sinian and Cambrian strata in Yunnan, G...

Abstract:
Dickite found in the shaft of Yungang Coal Field occurs in downcast pillar close to coal seams at the top of Datong Formation of Middle Jurassic. It fills in pores and cracks of rocks, being in spotted block and network of vein. The main characterist...

Abstract:
Before the introduction of the Fourier transform infrared (FTIR) spectrum, X-ray diffraction was probably the best method for the identification and guantitatire analysis of clay mineral mixtures. But the method is limited by problems of the overlayi...

Abstract:
There are at least dozens of modes to evaluate oil and gas resources. The selection of the evaluation methods must be based on the geologic conditions of a certain area, since the restrictive applicability of each method has been recognized. This pap...
