通过对地震剖面的连片解释和剖面构造演化研究认为,枫顺场—天井山构造自震旦纪以来经历了拉张成盆、陆隆伸展背景下的3期演化过程.震旦纪—中三叠世末以拉张成盆作用为主,接受了一套海相碳酸盐岩和碎屑岩地层沉积,该时期枫顺场—天井山构造不存在;晚三叠世—中侏罗世末为重力滑动阶段,位于重力滑动构造系统前锋推挤带的枫顺场—天井山区域发育以薄皮构造为主的一系列逆冲推覆构造;晚侏罗纪以来开始挤压造山运动,构造动力学背景由重力滑动逐渐转化为水平挤压,发生基底卷入变形,形成一系列以厚皮构造为主的前展式逆冲推覆构造,剥蚀后表现为现今的构造样式.%By the studies of the commingled interpretation and the structural evolution of the seismic profiles, Fengshunchang-Tianjing Mountain Tectonics has experience, the following three evolution process from Sinian to Now: extended to generate a basin, gravity gliding and compressional orogenesis under the background of the continental uplift and expansion. At the extensional basin stage (Z-T2) , there were no Fengshunchang-Tianjing Mountain structures, but sedimentated a series of sea facies carbonate and clastic formations. At the gravity gliding stage {T3-J2) , located in the front of the gravity gliding belt of the structural system, Fengshunchang-Tianjing Mountain regionally developed into a series of thrust nappe structures taking thin surface structure as the main form; since Late Jurassic period (J3-Q) , the compressional orogenesis has formed, the background of the structural dynamics changes gradually from stretching/gravity gliding to horizontal compression, accompanied with the basement-involved deformation, and then a series of advance thrust structures taking thick surface structure as main form are produced. After eroding, the above structures manifests as nowaday structural patterns.
