江西省境内中生代含煤盆地较为发育,而这些含煤盆地常具有一个普遍的特征,就是煤盆地多呈单翼不完整向斜,一翼常有逆断层而使老地层逆覆于煤系地层之上。对于这种单翼不完整向斜的形成机制,以往多解释为,在含煤地层形成之后,由于褶皱作用先形成完整的向斜形态,后经逆断层的破坏而形成的。 近年来,在煤田普查勘探工作中,为了

The Mesozoic coal-bearing basins in Jiangxi Province are relatively developed, and these coal-bearing basins often have a common feature that the coal basins are mostly single-limb incomplete synclines, one wing often has reverse faults and the old strata overturn coal-bearing strata on. In the past, the formation mechanism of the incomplete monotonic syncline was mostly explained by the fact that after the formation of the coal-bearing strata, a complete syncline was formed due to the folds and then formed by the reverse thrust faults. In recent years, in the coalfield census exploration work, in order
