The administrative division of Northwest China includes Qinghai, Gansu, Shaanxi Province, as well as the Uygur autonomous Region of Xingjiang and the Hui autonomous Region of Ningxia. Traditionally the Northwest China Coal accumulation Region is defined as vast extensive area located in the west side of the Helan-Liupan Mts and the north side of the Kulun-Qinling Mts. In fact, it is only a part of the Jurassic coal accumulation region in Northern China. The studied area of this book includes not only the most part of the above five provinces (autonomous regions), but also the Alxa and Ih Ju Leagues of the Inner Mongolia Autonomous Region. Its total area approaches to 1/3 of the territory space in China.
The Jurassic coal-bearing strata are well developed in Northwest China, especially in the Junggar, Yili, Turpan-Hami, Tarim, Qaidam and Ordos Basins, as well as the Beihan-Alxa, qilian and West Ordos Margin Basin Groups. According to the principles of modern multiple stratigraphy, a comprehensive research has made on the stratigraphic sequence, lithostratigraphic units and their deposystems, the major coal-bearing members and their coal-forming properties, the fossil flora and fauna as well as their assemblages of the Jurassic coal measures in the studied area. As a result, the chronostratigraphic correlations of the different lithostratigraphic units have been carried out in the different Jurassic coal basins.
