运用现实主义原则，依据构造动力作用方式及其效应的不同，系统探讨了本区燕山期演化历程，将其划分为四个演化阶段（Ｊ，Ｋ１早期，Ｋ１晚期，Ｋ２）。概括为“两次重要转折，两次陆内层流造山，两期伸展作用”。Ｊ，第一次陆内层流造山，以挤压机制为主，盆地面积进一步缩小，马超营断裂带叠加脆性改造，新断裂形成；Ｋ１早期，花岗岩浆突变式侵入，产生热隆作用，引起重力滑脱，盆地面积扩大，数量增多，以引张应力为主，是本区大地构造发展的第一次重大转折；Ｋ１晚期，产生具压剪性质呈平行等间距排列的原始北北东向断裂；Ｋ２，第二次陆内层流造山，深部物质调整方向改变，为本区大地构造发展的又一次重大转折，在北北东向断裂基础上，马超营断裂带东西向左行平移作用的参与，形成本区断陷盆地，以引张应力为主。
Based on the principle of realism and based on the difference of tectonic dynamic modes and their effects, this paper systematically explores the Yanshanian evolutionary history of this area and divides it into four evolution stages (early J1, early K1, late K2). Summed up as “two major turning points, two intra-layer flow of mountains, two stretch.” J, the first intracontinental orogenic flow, mainly by the extrusion mechanism, the basin area is further reduced, the Ma Chao camp fault superimposed brittle transformation, the formation of new faults; K1 early, granite magma mutagenesis, resulting in the role of Ge Long, causing Gravity slip, the basin area expanded, the number increased, with tensile stress-based, is the first major turning point in the development of the tectonic structure of this area; in the late stage of K1, the original NE-trending eastward fault ; K2, the second intracontinental flow orogeny, the depth of the material adjustment direction changes for the regional geotectonic development of another major turning point in the north-north east fault on the basis of the Ma-Ying Ying fault east-west line to the left of the line translation Participate in the formation of faulted basins in this area, with tensile stress-based.
