河北三迭系系指位于二迭系之上、侏罗系或第三系不整合面之下的一套红色地层,属陆相碎屑岩及泥质岩建造,总厚935～1610.8米。主要分布在河北北部的承德县下板城、武家厂和平泉县小寺沟、广兴店、营子及松树台一带(图1);另外在河北南部的武安县流泉村,临城县北盘山,后郝平,内邱县磁屏,峰峰鼓山东麓大淑村等地亦有零星出露。河北三迭系的划分和时代归属的确定,具有很重要的理论和实践意义。因为它不仅直接关系到中国北方陆相三迭系的分布问题、与欧亚大陆陆相三迭系的对比问题,以及印支运动在我国北方的表现等问题,而且还同国家急需的某种矿产有密切联系。
Hebei Triassic refers to a set of red formations above the Permian, Jurassic or Tertiary unconformities that are composed of continental clastic and argillaceous rocks with a total thickness of 935 to 1610.8 meters. They are mainly distributed in Xiaban City, Wujia Plant and Xiaotinggou of Chengquan County, Chengde County, Guangxingdian, Yingzi and Songshuidai of Chengde County in the northern part of Hebei Province (Fig. 1). In addition, in Liuquan Village, Wu’an County, Hebei Province, Panshan, Hao Ping, Neiqiu County magnetic screen, peak Fengshan Dashu Village East also sporadic out. The division of Triassic series in Hebei Province and the determination of attribution of the times have very important theoretical and practical significance. Because it is not only directly related to the distribution of the terrestrial Triassic system in northern China, the contrast with the territorial Triassic system in Eurasia, but also the performance of the Indo-Chinese Movement in northern China and other issues, and it is also closely linked to a certain kind of mineral urgently needed by the country .
