General review of tectonic history and further careful Some kinds of techniques on brittle, brittle-ductile, and research on deformed coal rocks form the basic way to clarify ductile deformation zones are very important for future problems of coalbed gas genesis. research.

X. Li et al. took use of the areas, and also the related coalbed gas genesis study in this Fourier transform infrared and Raman Spectral to study the most important coalbed gas product area of China. metamorphism and deformation of coal. J. Fan et al. gave Geometry, kinematics, and geochronology data from us one new coal rank evaluation method by total scanning outcrops of the China Central Orogen and the North China fluorescence characteristics. offered excellent clues of extension event for understanding In general, the eleven papers here constitute a significant the tectonic conditions of coalbed gas.

The papers also laid a research system for further Central Orogen of China, related to Tethys Closure and work of coal geology. mainly formed during the Triassic Period, includes both the Qinling Orogen in the west and the Dabie Mountains in Quanlin Hou the east.

Q. Hou clarified Yudong Wu the framework of the Dabie Extensional Tectonic System. Furthermore, Q. Liu made out the different origins of the fractionation of Platinum-Group elements in Raobazhai and Bixiling Mafic-Ultramafic Rocks from the Dabie Orogen. Several achievements of coal field research in Northern China showed us the characteristics, developments, and genesis of coalbed gas. Y. Ju et al. gave us general properties of tectonically deformed coal rocks. J. Fan et al. studied the characterization of coal reservoirs in two major coal fields of China. Y. Wu et al. showed a case study of vitrinite anisotropy from Huaibei Coalfield from southern North China.

A previous study of the Dabie area has been supposed that a strong extensional event happened between the Yangtze and North China blocks. The entire extensional system is divided into the Northern Dabie metamorphic complex belt and the south extensional tectonic System according to geological and geochemical characteristics in our study. The Xiaotian-Mozitan shear zone in the north boundary of the north system is a thrust detachment, showing upper block sliding to the NNE, with a displacement of more than 56 km. However, in the south system, the shearing
