摘要： 依据断层的作用形式将正反转构造分为单一型和复合型两大类。因受力方式的不同,单一型正反转构造可细分为挤压倾滑型、压扭型和走滑诱导型3亚类7小类；复合型正反转构造可细分为挤压倾滑复合型和压扭复合型2亚类8小类。论述了各类正反转构造的形成机制、平面和剖面的识别标志,并对每类正反转构造的特征进行了实例说明。分析认为,绝大多数正反转构造产生于张性盆地演化的反转期,即应力场转变为压应力场的时期。

Abstract: According to the faulting style, positive reversed structures can be divided into single type and composite type, where the single type can be subdivided into three subtypes (including seven minor types),such as compressional dipslip one,compressional torsion one and strike-slip induction one; the composite type can be subdivided into two subtypes(including eight minor types), such as compression and dip-slip composite one and compression and torsion composite one. The formation mechanisms and recognition markers in plane and cross section for each structure were discussed. The characteristics of each one were demonstrated and analyzed by means of the cases. It is considered that the most positive reversed structures were formed in reverse motion stage(i.e. stress field was transformed to compressive stress one) of tensional basin evolution.
