passive continental margin

There are some differences between the two types of foreland basins: ( 1) The epicontinental foreland basin went through passive continental margin or retro?-arc rift stage during tectonic evolution stage, but the intracontinental foreland basin lacked this period.

它们之间的主要区别表现在：（1）从盆地构造演化上看，陆缘前陆盆地经历了裂谷被动边缘或弧后裂谷阶段，陆内前陆盆地则缺乏这一阶段；

The sedimentary tectonic setting during Mesozoic was mainly the continental island arc, and in Trias& Jurassic sometimes was the stable-passive continental margin. And in the period of early Cretaceous the setting was more active, sometimes with the characteristic of the active continental margin.

3中生代时期，构造环境复杂，大陆岛弧型为主，三叠纪&侏罗纪期间处于转型期，兼有稳定的被动大陆边缘型特征，早白垩世兼有活动大陆边缘型特征，构造环境更为活化。
