Study on High Metamorphic Coal Belts Origination and Coalbed Methane Enrichment in Central and Southern Parts of North China Plate

In order to make sure the formation mechanism and age of the high coal metamorphic belts in central and southern parts of the North China Plate. The tr ansition of the North China plate tectonics in the late Paleozoic, lithospheric thinning, distribution of magmatic activity stages, characterization of high coal metamorphic belts, as well as the fact of coalbed methane enrichment of Chinese high metamorphoic coal belts had been studied in order to explore the existence of different unders tandings of the causes of high metamorphic coal belts in central and southern parts of the North China Plate. High metamorphic coal belts in the southern parts were fo rmed at the trailing edge of the North China Plate due to the Yangtze-North China Plate Indosinian collision collage in Triassic. The middle of the so-called east-west hi gh metamorphic coal belt formation was the result of Telemagmatic or Hypabyssal magmatic rocks development along Tanlu, Taihang fault belts and Shanxi rift zone. In addition to the high metamorphic coal which was often favorable coalbed methane-rich region, the Yanshan active region of magmatism was also favorable area for coal bed methane ( CBM) exploration. Combined the study of tectonothermal the structure, magmatism, metamorphism and regional deposition tectonothermal evolution wer e an effective method to explain the central and southern high coal metamorphic belt formation of the North China Plate and CBM forecast.
