Early Cenozoic Multiple Thrust in the Tibetan Plateau
Figure 2
Paleotectonic map of the Tibetan Plateau for the Late Eocene-Oligocene. Explanation: 1: major thrust fault; 2: thrust fault; 3: nappe or outlier; 4: strike-slip fault; 5: ductile shear zone; 6: Late Eocene-Oligocene granite; 7: granitic dome; 8: ophiolite along the Yarlung Zangbo Suture (YZS); 9: Late Eocene-Oligocene volcanic rocks; 10: Oligocene (E3) terrestrial strata; 11: Oligocene basin; 12: Paleocene-Eocene (E1+2) strata; 13: erosion area; 14: present-day lake. Major fault systems: ATF: Altyn Tagh Fault [5, 8]; WKT: West Kunlun Thrust; SKT: South Kunlun Thrust [11]; HXT: Hohxil Thrust; NTT: North Tangula Thrust [12], DCT: Dogai Coren Thrust; LCT: Longwei Co Thrust; NCT: north central Thrust; XST: Xiaocaka-Shuanghu Thrust; DQT: Doma-Qixiang Co Thrust; SZT: Saibu Co-Zagya Thrust; NST: Nima-Silin Co Thrust; BNT: Bangoin-Nujiang Thrust; NGT: North Gangdese Thrust; CGT: Central Gangdese Thrust; GTS: Gangdese Thrust System [13]; RZT: Renbu-Zedong Thrust [13, 14]; MCT: Main Central Thrust [15, 16]; MBT: Main Boundary Thrust after Mid Miocene [5]. Black dots mark sampling location for isotopic ages and outcrops for photos, and dotted lines A-B, C-D, E-F, and G-H mark positions of regional cross sections.
