太子河流域煤田西部区（如本溪煤田和红阳煤田）为旋卷构造和伸展构造所控制；受太平洋板块对大陆边缘俯冲和大陆的仰冲先后产生旋扭和拉张形成上述两种构造类型，形成时间为晚侏罗世至早第三纪。
The western part of the Taifzehe valley(Benxi coal-field and Hlongyang coal-field)were controled by vortex structure and stretch structure and strectch Structure., The conti-nental margin and the continent affected by underthrust and obdnction of the Pacific Plate. vortexand stretch sttuctures had produced respectively and two types of structure mentioned above wereformed during Late furassic to Early Tertiary.
