中文摘要: "华北系"是华北地块新生代时期普遍发育的NNW向构造体系。昌围地区是华北地块的一个缩影,特别是伊逊河-滦河构造带,集中了全区3个带、61个NNW向压性或压扭性构造点中的40%,活动构造现象十分典型,又称"滦河系"。通过相应的配套构造组合分析,应力测量和震源机制解等资料论证,华北系主压应力方向为NEE-SWW,动力来源于地球自转,是由太平洋地块向SWW对华北地块推挤,后受阻于青藏地块而产生强大的反作用力而形成的。

Abstract:The "North China system" is a tectonic system that trends NNW and was widely developed in the North China Block in Cenozoic with the Changping-Weichang area as a type locality. It is also called "Luanhe tectonic system" because about 40 percent of their occurrences are concentrated in the Yixunhe-Luanhe tectonic belt. By an analysis of the accompanying structural features and by referring to stress measurements and focal mechanism solutions,the principal compressive stress responsible for the "North China system" was determined to be ENE-WSW oriented. It is believed that the WSW push by the Pacific Block toward the North China Block met with the resistance of the Qinghai-Tibet Block would produce such a regional stress field in the North China Plain.
