The Lower Triassic sedimentary and carbon isotope records from Tulong (South Tibet) and their significance for Tethyan palaeoceanography

The Buday’ah Formation, Sultanate of Oman: A Middle Permian to Early Triassic oceanic record of the Neotethys and the late Induan microsphere bloom

“…Sperling and Ingle (2006) also reported this event in the Black Rock terrane series of Nevada. A similar ''microspheres'' horizon is reported in Unit 1b at Tulong (S. Tibet, Brühwiler et al, 2009) and at the base of the Feixianguan Formation of Laolongdong (Sichuan, China, Wignall and Twitchett, 1996).…”

“…A similar transition is recorded in the upper Olenekian slope deposits of the Sumeini nappe where Spathian shale (Maqam D) overlies upper Smithian platy limestone (Maqam C; Richoz et al 2005). In Tulong (S. Tibet) there is a similar succession with Smithian thinbedded limestone overlain by Spathian green shale (Brühwiler et al, 2009). However, thin limestone beds occur in the basal part of the shale succession at both of these localities.…”

A new high-resolution δ13C record for the Early Triassic: Insights from the Arabian Platform

“…By contrast, sections with notable lithological variations show different excursion profiles. For example, in Spitsbergen (Galfetti et al, 2007c) and Tibet (Brühwiler et al, 2009) more positive values correlate with carbonate beds and more suppressed values in surrounding shales. Again for L'Om Picol the direct link to lithology is not clear but the record is highly fluctuating at the Smithian/Spathian boundary.…”

“…4) to studies in other Tethyan (Payne et al, 2004;Richoz, 2006;Galfetti et al, 2007a;Horacek et al, 2007aHoracek et al, , 2007bBrühwiler et al, 2009;Meyer et al, 2011) and Panthallassic (Horacek et al, 2009) localities. However, additional features are resolved here, perhaps attributable to the high rate and near-continuous nature of sedimentation and the lack of major depositional facies changes.…”

Catastrophic environmental transition at the Permian-Triassic Neo-Tethyan margin of Gondwanaland: Geochemical, isotopic and sedimentological evidence in the Spiti Valley, India

“…P-Tr studies from China (Payne et al, 2004;Zhang et al, 2007;Zhou and Kyte, 1988), Vietnam (Algeo et al, 2008;Algeo et al, 2007a), northern Indian margin (e.g. Algeo et al, 2007b;Baud et al, 1996;Brookfield et al, 2003;Kummel and Teichert, 1970;Nakazawa et al, 1975), Tibet (Bruwiler et al, 2009;Garzanti et al, 1998;Shen et al, 2010;Wignall and Newton, 2003;Yuan et al, 2014), Canadian Arctic (Algeo et al, 2012;Beauchamp et al, 2009;Grasby and Beauchamp, 2008;Beauchamp, 2009), Southern Alps (Fenninger, 1991;Holser et al, 1989), Iran/Oman (Korte et al, 2004;Richoz et al, 2010) and Antarctica (Retallack…”
