...Gregory A. Davis; Brian J. Darby; Zheng Yadong; Terry L. Spell Abstract The Early Cretaceous Hohhot metamorphic core complex and its master Hohhot detachment fault are ∼400 km west of Beijing in the Daqing Shan (Mountains) of Inner Mongolia. The complex developed across the east-trending Yinshan...

Structural geological map of the Hohhot metamorphic core complex (located in fig. 1) and its cross-section drawn parallel to the direction of the main stretching lineation [Modified from Davis et al., 2002; Wang et al., 2002]. The pluton roots are hypothetic; top to the south contractional deformation is not represented here.

Figure 1. Simplified tectonic map of Hohhot metamorphic core complex (MCC) based on our mapping and that of Nei Mongol Bureau of Geology and Mineral Resources. Note multiple, folded detachment faults on north flank of Daqing Shan antiform. Extension direction is northwest-southwest, parallel to antiformal and synformal (not shown) primary corrugations of detachment faults; shear sense for both detachment faults and footwall mylonitic rocks was top-to-southeast.

Figure 2. Simplified cross section of Hohhot core complex as we mapped and interpreted it. Fill patterns as in Figure 1. Geology at depth under Early Cretaceous clastic and volcanic sequence in southeastern portion of cross section is undefined. Total displacement on detachment system is >40 km. Dashed lines represent projection of since-eroded structure.

Figure 3. Evolution of Hohhot detachment fault system. Single Hohhot detachment along south flank of Daqing Shan is master fault, whereas synformally folded faults to north are splays (lowermost oldest) that were active for only part of core complex evolution. A: Initial displacement (1) on south-dipping detachment. B: Isostatically related(?) folding of detachment fault (1) and generation of planar splay (2) as detachment continues. C: Continued folding of detachments (1) and (2) and generation of second planar splay (3).

Map of southern Mongolia and adjacent areas of China showing known Late Jurassic–Cretaceous rifts, areas of Cretaceous basin fill, and extensional detachment fault-bound metamorphic complexes. The exhumed extensional detachment faults and metamorphic footwall domes in the NW Altun and Nemegt ranges indicate that a Late Jurassic–Cretaceous extensional province characterized by NW–SE crustal stretching occurred over a wider region than previously recognized, including the southern Gobi Altai region. Late Cenozoic crustal reactivation and sinistral transpressional mountain building in the Gobi Altai (eastern and southern limit indicated) overprints and obscures the Late Jurassic–Cretaceous phase of rifting, making it more difficult to recognize. Extensional basins in China taken from Meng (2003) and Meng et al. (2003); Cretaceous basin fill in Mongolia taken from Sodnom &amp; Yanshin (1990). Faults in NE Mongolia taken from Graham et al.
