塔里木盆地中生代含煤建造与构造关系

根据塔里木盆地及周缘地层层序及其构造轮廓特征，讨论了盆地坳陷区内煤建造，在此基础上分析了这些含煤区与塔里木占陆块的构造形态之间的关系,含煤区的古构造条件，古地理环境的关系，指明了进一步工作方向。

MESOZOIC COAL-BEARING FORMATIONS AND STRUCTURES OF TARIM BASIN

Tarim basin formed by compression and twisting, with a series of nearly EW-trending folds and faults developed within the basin and at fronatal margins of the mountain ranges on both sides of the basin. Another two sets of NE-NEE and NW-NWW trending faults control the structural framework of Tarim basin. The EW-trending uplifts and depressions which formed during the Paleozoic affect directly the development of various Mesozoic structural basins. According to the characteristics of overall structures of the basin, four structural domains are classified, i.e., northern Tarim depression zone, central Tarim uplift zone, southwestern Tarim uplift-depression interval zone and southeastern Tarim fault bench zone. There are three sets of coal-bearing formations in the Tarim area, i.e., Talijik Fm. (T3-T1)t including part of the transitional beds of Upper Triassic to Lower Jurassic, belonging to coal seams of set A; Yangxia Fm. (J1y) and Kezilur Fm. (J2k), respectively containing coal seams of set B and set C. According to paleo-structural and paleogeographical conditions, four coal-bearing regions are subdivided within Tarim basin, i.e., northern Tarim depression, central Tarim depression, southwestern Tarim depression and southeastern Tarim depression.
