饶阳凹陷马西断裂分段性研究

Branch study on Maxi break in raoyang depression

冀中凹陷饶阳凹陷马西断裂具有分段性,且各段几何特征特征存在差异,根据展布方向的不同将其划分为北段NNW向、中北段近NS向、南段NEE向三段;根据成因分为走滑断层、伸展正断层、横向调节断层。各分段断层的结构、形态、伴生构造活动时间及对沉积作用的控制等都存在较明显差异,断层的分段处是马西洼槽主要物源区。

There are characters of branch and difference of Maxi break in Raoyang depression of Jizhong depression basin, it is divided into Northern part （NNW）, Middle-northern part （NS） and Southern part （NEE） based on throughgoing, and it is divided into strike-slip fault, extend down fault and controlled fault of horizontal based on contributing factor. Composition, form, associated structure active tine and sedimentation control of branch faults have apparently difference, place of branch faults is main provenance of Maxi break.
