Paleomagnetic study of Cretaceous rocks from Pu'er, western Yunnan, China: Evidence of internal deformation of the Indochina block

New paleomagnetic studies of Cretaceous and Miocene rocks from Jinggu, western Yunnan, China: Evidence for internal deformation of the Lanping–Simao Terrane

“…7b), indicating that the magnetic fabric was formed during compressional tectonics (Mattei et al, 1997). Parallelism between k 1 and the fold axis direction within the Lanping-Simao Basin was also recognized in the Simao area (Sato et al, 2007), which further confirms the tectonic origin of the observed magnetic lineation, implying that k 1 is a passive marker that was rotated after formation as part of stratal shortening (Fig. 7c).…”

Paleomagnetism of Upper Cretaceous red-beds from the eastern Qiangtang Block: Clockwise rotations and latitudinal translation during the India–Asia collision

“…Paleomagnetic and geological studies in the Indochina Block and Shan-Thai Block in the southeastern edge of Tibetan Plateau favor the conspicuous lateral extrusion movement of these two blocks since the Oligocene (Leloup et al, 1995(Leloup et al, , 2001Gilley et al, 2003;Otofuji et al, 2007;Yang and Besse, 1993;Yang et al, 1995Yang et al, , 2001Zhang et al, 2012). Furthermore, the Indochina and ShanThai Blocks underwent $35°clockwise rotational movement relative to the South China Block in the process of southeastward escape movement (Sato et al, 2007;Otofuji et al, 2007;Tanaka et al, 2008;Tong et al, 2013;Yang et al, 1995;Zhang et al, 2012;Kornfeld et al, 2014). The Mangkang area also experienced obvious southward displacement ($7.3 ± 5.2°to $3.2 ± 7.8°) and clockwise rotation since the Cretaceous (Fig.…”

Oligocene-Early Miocene river incision near the first bend of the Yangze River: Insights from apatite (U-Th-Sm)/He thermochronology

“…(SBGMR, 1991;Spurlin et al, 2005). These basins were rearranged by extrusion of the Indochina Block (Wang and Burchfiel, 1998), as evidenced by palaeomagnetic studies indicating that NW Yunnan has undergone ~90-45° of clockwise rotation (relative to the South China Block) since the Oligocene (Sato et al, 2007). (3) Recent studies reported several late Oligocene -early Miocene transpressional structures in the southeastern Tibetan Plateau (Tapponnier et al, 2001;Wang et al, 2012)…”
