摘要：
The Yanshanian orogeny has affected extensively the tectonic evolution of the East Asia, however, the beginning and the deformation patterns of the event are still hotly debated. The Jurassic Ningwu-Jingle Basin, a NE-SW trending syncline basin in the northern central part of the North China Craton, provides an example for the study of the Yanshanian Orogeny. The Ningwu-Jingle Basin is located in the Lüliang-Taihang Mountains between the North China Plain Basin and the Ordos Basin. In this paper, the structural patterns and the prototype of the Jurassic Ningwu-Jingle Basin are determined through tectonic deformational analysis and reconstruction of balanced cross-sections, and the basin-mountain coupling effects of the Yanshanian Orogeny are discussed through detrital zircon U-Pb dating of the growth strata. Structural geological investigation reveals different structural patterns in different parts of the synclinal Ningwu-Jingle Basin. Fault-propagation folds occur in both the west and east limbs of the synclinal basin. In the west limb of the syncline, face to face compressive structures, back thrusts and imbricate thrusts, occur in the northern part, the middle part, and the southern part of the basin, respectively. The growth strata consist of the Middle Jurassic Yungang Formation (J2y) and the Upper Jurassic Tianchihe Formation (J3t), recording the obvious formation and tectonic deformation of the synclinal Ningwu-Jingle Basin resulting from the Yanshanian Orogeny during the Middle to Late Jurassic. Crust shortenings recorded by the pre-growth strata are ca. 26.2% (or ca. 13 km) for the middle part and ca. 58.6% (or ca. 34.6 km) for the southern part of the synclinal basin, respectively. Detrital zircon U-Pb dating constrains the oldest age of the Middle-Late Jurassic growth strata at ca. 168 Ma, which suggests the triggering of the Yanshanian Orogeny at ca. 168 Ma. It is considered that the Yanshanian Orogeny in the Middle to Late Jurassic led to the uplift of the Lüliang and Taihang Mountains in the northern central part of the North China Craton. © 2019, Science Press.
