凯里地区逆冲推覆—滑脱构造特征

Dertachment Thrust in Kaili, Guizhou

施洞口断裂是贵州东南部一条重要的断裂带,在它的逆冲推覆作用过程中,逆冲推覆构造的不同地段,其应力分布、构造变形特点都有一定差异。而逆冲推覆构造所产生的巨大水平挤压力在地台盖层中亦可产生构造变形。由于盖层结构中物质具垂直分带,各构造亚层变形特征也各具特点。

Shidongkon thrust in southern Guizhou is an important fault zone. As a result of its thrusting, two terrains of different tectonic units and levels were conjoined. During its thrusting, the structure deformations with different styles anddegrees formed. For the lower plate of the main-slide plane. the brittle deformation domimated. the vertical zonation of its rock resulting in defference in deformations of the structure sub-levels. However, the upper plate of the main-slide plane is characterized by the ductile deformation, but in various parts of the thrust, the stress distribution and structure deformation being defferent.
