| 摘 要： | 柴达尔井田构造可分为压缩机制的推覆构造与伸展机制的断块体两类。南北F0为逆冲型的控制性边界断裂，井田内部一系列小型弧形构造为逆掩型浅层断裂；F1、F2、F17，是拉伸作用下的同沉积正断层，切断煤系基底T3地层。其动力机制为印度板块向北推移、西伯利亚板块向南运移发生对挤，脆一韧性剪切变形导致了井用现有的构造组合形式。

| Abstract: | The nappe structural assemblage forms in the minefield can be divided into two kinds of compressed nappe structures and extended block structures. The NS Fo is a controlling boundary thrust; a series of small arcuate structures in the interior minefield are shallow overthrusts; F1, F2 and F17 are extended synsedimentary normal faults, which cut the T3 coal measures basement strata. The structural dynamic mechanism is compressing northward Indian Plate and southward Siberian Plate caused brittle - ductile shearing deformation in upper crust, thus the minefield structural assemblage forms were formed. |
