The role of strike-slip faults in the displacement of the Palaeotethys suture zone in Southeast Thailand

The volcaniclastic series from the Luang Prabang Basin, Laos: A witness of a triassic magmatic arc?

“…Some of these suture zones were reactivated and/or offset by Cenozoic shear zones such as the Dien Bien Phu Fault (Roger et al, 2014), the Mae Ping Fault (e.g., Ridd, 2012) or the Red River Fault (e.g., Faure et al, 2014).…”

“…The northern continuation of the Simao Block and possible links with the Qiangtang or Qamdo blocks (e.g., Metcalfe, 2011) will no be discussed here. Besides, the southern continuation of the Simao Block and possible links with the Chanthaburi arc terrane (e.g., Metcalfe, 2011) or the Klaeng terrane (e.g., Ridd, 2012) is beyond the scope of this paper. Roger et al, 2014), these oceanic domains were probably connected together (Fig.…”

“…14 D). Even though speculative given the present day remote location of the Luang Prabang Basin with respect to the Malay Peninsula, and the potential large tectonic offset between these areas (e.g., Ridd, 2012), there are some striking similarities regarding their Late Triassic geodynamic evolution. Particularly, the timing and the dipping of the subduction in the Luang Prabang area compare well with the Late Triassic subduction described in Peninsular Malaya (e.g., Searle et al, 2012;Metcalfe, 2013).…”

A Middle Permian–Middle Triassic accretionary complex and a Late Triassic foredeep basin: Forerunners of an Indosinian (Late Triassic) thrust complex in the Thailand–Malaysia border area

“…In northern and SE Thailand the volcanic arc which formed during the closure of Palaeotethys above the east-dipping subduction zone on the (present) west side of the Indochina block was for a time separated from the Indochina block itself by a back-arc basin (Ueno and Charoentitirat, 2011;Ridd, 2012). (In the Late Palaeozoic and Triassic the movement of the tectonic plates was in the southnorth direction, and so subduction at that time was northward).…”

“…1). The site of the ancient Palaeotethys ocean is represented in northern Thailand by the Chiang Rai line (the 'cryptic suture' of Barr and Macdonald, 1991), in SE Thailand by the Klaeng Fault zone (Ridd, 2012), and in Malaysia by the Bentong-Raub suture, although as will be shown here the Palaeotethys accretionary complex and the associated, but later, foredeep basin extended some way to the west of the Bentong-Raub suture zone (sensu stricto), as suggested by Spiller and and Spiller (2002).…”
