Permian radiolarian faunas from Thailand and their paleogeographic significance

Discovery of Lower Permian Radiolarian and Conodont Faunas from the Bedded Chert of the Chanthaburi Area Along the Sra Kaeo Suture Zone, Eastern Thailand

“…L. texana has been recovered from the Middle Permian, North America, Southwest Japan, South China (Nazarov and Ormiston, 1985;Wang, 1991;Blome and Reed, 1992;Wang and Li, 1994;. L. asperspongiosa has been reported from the Upper Permian in Japan, North America and Northern Thailand (Sashida and Tonishi, 1986;Blome and Reed, 1992;Sashida and Salyapongse, 2002). Furthermore, S. minuta was discovered in the upper Middle Permian to lower Upper Permian of eastern Thailand by .…”

“…Knowledge of the precise ages of siliceous sedimentary rocks and associated fine-grained clastic rocks in Thailand has rapidly grown thanks to several authors (e.g., Caridroit, 1991Caridroit, , 1993Caridroit et al, 1992;Sashida et al, 1993aSashida et al, , 1998Sashida and Salyapongse, 2002). Permian radiolarian biostratigraphy in Thailand and its paleogeographic significance were summarized by Sashida and Salyapongse (2002).…”

“…Permian radiolarian biostratigraphy in Thailand and its paleogeographic significance were summarized by Sashida and Salyapongse (2002). They proposed the following four Lower Permian radiolarian assemblages: the Parafollicucullus bulbosus (Upper Carboniferous to lowermost Permian; upper Gzhelian to lowermost Asselian), Parafollicucullus simplex (lowermost Permian; Asselian), Parafollicucullus lomentarius (Lower Permian; Asselian to Sakmarian), and Pseudoalbaillella scalprata (Lower Permian; Sakmarian).…”

Lower Permian conodonts from Palaeo-Tethys Ocean Plate Stratigraphy in the Chiang Mai-Chiang Rai Suture Zone, northern Thailand

“…Oceanic rocks, now incorporated in the accretionary complex, include mid-ocean ridge basalts (MORB), pelagic radiolarian chert, pelagic limestone, and pelagic mudstone and turbidites. Pelagic chert contains radiolarians ranging in age from Middle Devonian to Middle Triassic (Caridroit et al, 1992;Caridroit, 1993;Caridroit et al, 1993;Sashida et al, 2000;Feng et al, 2002;Sashida and Salyapongse, 2002;Caridroit, 2005, 2007;Ueno and Charoentitirat, 2011;Hara et al, 2010;see Fig. 5 …”

Geochemical constraints on the depositional environment of Upper Devonian radiolarian cherts from Loei, north-eastern Thailand

“…This first report on geochemistry of cherts in Thailand indicates that the main Palaeotethys should be located further to the west of Nan-Uttaradit Suture. Beside the Triassic cherts, there are Devonian, Carboniferous and Permain radiolarian cherts which have been reported in northern, western, southern and north-eastern Thailand (e.g., Caridroit, 1993;Sashida and Igo, 1999;Sashida et al, 2000;Sashida and Salyapongse, 2002;Feng et al, 2002, 2004, 2005, Thassanapak et al, 2007.…”
