摘要
兴城地区在前侏罗纪时期区域大地构造位置位于华北地台北部燕山沉降带东段。辽宁又是中、新生代时期中国东部大陆边缘活动带组成部分，属太平洋构造域，两大构造域交接复合，区域地质构造复杂。华北地台在早元古代末，吕梁运动以后长期以来（尤其是古生代阶段）表现为相对稳定的地区，进入中、新生代时期，尤其是燕山构造旋回，地台的构造运动和岩浆活动都加强了，显示出相当强的活动性。在这里发现了举世闻名的中华龙鸟、孔子鸟和世界最早的被子植物—中华古果，以及热河生物群。可以说，兴城地区是一处得天独厚的地学天然实验室。
Abstract
Before Jurassic，Xingcheng area is located in the east section of Yanshan subsidence zone in the north of North China platform. In Mesozoic and Cenozoic，Liaoning is one constituent part of continental margin active belt in the east part of China which belongs to the Pacific tectonic domain. The North China platform is characterized by relatively stable area for a long time（especially the Paleozoic stage）since Luliang movement at the end of early proterozoic. Entering Mesozoic and Cenozoic period, especially during the Yanshan tectonic cycle, the tectonic movement of platform and the magma activity is strengthened, showing considerable activity.people found the world-famous sinosauropteryx, Confucius and the world's oldest angiosperms—the Chinese ancient fruit, as well as the jehol biota.Xing-cheng region is a unique study natural laboratory.
