文章系统地总结了永定地区聚煤盆地的滑覆、推覆构造存在Ⅱ类Ⅴ型,即因重力作用产生的滑覆构造和因水平力作用产生的推覆构造(Ⅱ类)。滑覆构造分为脱底、层间、脱顶构造(Ⅲ型);推覆构造又分为燕山早期的层间推覆、燕山晚期的基底逆冲构造(Ⅱ型)。开展此项研究为永定地区进一步寻找富煤带指明了方向。
The article systematically summarizes the slippery coal accumulation in the coal accumulation basins in Yongding area. There are Ⅱ type Ⅴ types in the nappe structure, ie, the slip-slip structure due to gravity and the nappe structure due to horizontal force (Class Ⅱ). The slip-slip structure is divided into the bottom, the interlayer and the top-off structure (Type Ⅲ). The nappe structure is divided into the early Yanshanian interlayer nappe and the Late Yanshanian basement thrust structure (Type Ⅱ). Carrying out this research indicates the direction of further searching for coal-rich zone in Yongding area.
