The Permian fusulinoidean faunas of the Sibumasu and Baoshan blocks: their implications for the paleogeographic and paleoclimatologic reconstruction of the Cimmerian Continent

Depauperate fusulinid faunas of the Tengchong Block in western Yunnan, China, and their paleogeographic and paleoenvironmental indications

“…It is an endemic genus in the Western Tethys Province and constitutes a typical combo associated with Rugososchwagerina or Xiaoxinzhaiella (Ueno, 2003;Shi et al, 2005). This combo is absent in the Tengchong Block, but thrived in both Baoshan and Lhasa blocks.…”

Petrogenesis of the early Eocene I-type granites in west Yingjiang (SW Yunnan) and its implication for the eastern extension of the Gangdese batholiths

“…The block is the northern extension of the Shan-Thai Block of the Cimmerian and was accreted to Eurasia in the late Mesozoic period (Shi et al, 1995;Metcalfe, 1996aMetcalfe, ,b, 1998Shi and Archbold, 1998;Ueno, 2003). Its main petrological components include the Gaoligong metamorphic rocks previously mapped as Proterozoic basement, Paleozoic low-to medium-grade metamorphosed sequence, Mesozoic-Tertiary granites and Cenozoic volcanic-sedimentary packages (e.g., Yunnan Mitchell (1993) and Chung et al (2005)).…”

“…BGMR, 1990). The Paleozoic sequences are mainly composed of weakly metamorphosed sandstones, shale/slate and limestone along with the interlayered glacial conglomerate and shale with Gondwana-type cold-water fossil species (e.g., Wang, 1983;Wu et al, 1995;Metcalfe, 1996b;Zhong, 1998;Ueno, 2000).…”

Late Palaeozoic and Mesozoic tectonic and palaeogeographical evolution of SE Asia

“…This major biogeographical divide has been termed the 'Gondwana-Tethys Divide' or 'Gondwana-Cathaysia Divide' by some workers and has been used to mark the boundary between Gondwana-derived continental terranes in the west, with Early Permian cold-or coolclimate sediments and biota, from warm-climate equatorial Cathaysian continental terranes to the east (Ueno 2003;Metcalfe 2005). It was the recognition of this major biogeographical divide, coupled with Late Carboniferous -Early Permian diamictites interpreted to be of glacial-marine origin, that led to models of Gondwana dispersion and Asian accretion of terranes derived from Gondwana (e.g.…”
