摘要
Abstract
The contemporaneous tectonic activity accompanying the coal accumulation from the beginning to the end has direct effect on the development degree of coal-bearing strata, and the original thickness and structure of coal seams in the Early-Middle Jurassic in Xinjiang. The synsedimentary tectonic activity, controlled by the Tethys-Himalayan geodynamic system, mainly shows synsedimentary reverse thrust and normal faults in the period. As a result, the subsidence velocity and range of the basement of coal-accumulating basins differ obviously in the Early-Middle Jurassic period in Xinjiang. Under the control of the Tethys-Himalayan geodynamic system, the depocenter and coal-bearing center of the coal-accumulating basin in the Early-Middle Jurassic period in Xinjiang show a tendency of migration from the west to the east and from the south to the north. Comparing coal-bearing region scale, the coal-accumulating strength and the overall subsidence range of the basement of basin present a negative correlation; Comparing coal basin or coal field scale, the relationship between the coal-accumulating strength and the subsidence velocity of the basin basement present positive correlation, parabola and negative cor-relation respectively.关键词
