Abandoned quarries contain chert and basalt clasts in a volcaniclastic matrix and may constitute a mélange. A new, recently active, quarry contains these rock units in close and coherent contact but they lack the serpentinitic matrix of the Thung Kabin Mélange of eastern Thailand. The rock units are in close contact and may best be described collectively as a dismembered ophiolite. The mélange–ophiolite association constitutes a 3 km wide, 20 km long E–W belt separating a northern 200 km2 block of the mainly amphibolitic Pailin Crystalline Complex from a southern area of Triassic submarine fan siliciclastic rocks. The cherts yield the first documented radiolarian fauna from Cambodia and include a moderately well-preserved Asselian–Sakmarian age fauna consisting of Pseudoalbaillella sakmarensis, Pseudoalbaillella scalprata morphotype scalprata, Pseudoalbaillella sp. cf. P. simplex, Pseudoalbaillella u-forma morphotype II, Pseudoalbaillella sp. cf. P. elegans, Pseudoalbaillella sp. cf. P. lomentaria, Albaillella sp., Pseudoalbaillella spp., Trilonche? sp., Latentifistularia gen. et sp. indet. and Entactinaria gen. et sp. indet. The Pailin ophiolitic rocks, mélange and volcanic rocks occur within a generally E–W-trending belt, which suggests that the Sa Kaeo Suture does not extend southeastwards paralleling the Thai–Cambodian border, nor extend under the Cardamom Mountains but, rather, extends eastwards into Cambodia and possibly then turns southwards along the strike of the Pursat–Kampot Fold Belt.

Research paper thumbnail of The boundary between the Inthanon Zone (Palaeotropics) and the Gondwana-derived Sibumasu Terrane, northwest Thailand-evidence from Permo-Triassic limestones and cherts

The Boundary between the Inthanon Zone and the Gondwana derived Sibumasu Terrane , 2021

The boundary between tropical Permian faunas of the Inthanon Zone and Gondwana faunas in far NW T... more The boundary between tropical Permian faunas of the Inthanon Zone and Gondwana faunas in far NW Thailand has been long debated. Both the Late Devonian and the Permian Gondwanan platform margins lie a few kilometres west of the Mae Yuam/Mae Sariang Fault (MYMS FZ). In the Permian, the margin grades eastwards into hemipelagic radiolarites along the MYMS FZ and westwards into the Thitsiphin carbonate platform of Myanmar. The area west of the MYMS FZ is the Northern part of the West Thailand Region (NWTR). Quartz-rich limestones of Roadian age in the NWTR are succeeded by deep-water platform limestones in the NWTR and shallow-water carbonates in Myanmar and contain a distinctive fusulinid fauna including Monodiexodina which does not occur in palaeotropical terranes. A 300-m section of limestone 10 km west of the MYMS FZ contains Wordian microfauna and is placed in a deep shelf to slope environment. Carboniferous to Triassic continental margin, hemipelagic, non-hydrothermal, radiolarian cherts outcrop on either side of the Mae Yuam valley and were deposited on the upwelling margins of an ocean separating the Inthanon Zone and Sibumasu Terrane. The widely accepted allochthon model proposes that the Inthanon Zone Devonian-Triassic radiolarites were pelagic and deposited on a subducting ocean that supported seamounts with Visean to Permian tropical shallow-water carbonates lasting at least 90 my. We suggest an alternative hypothesis where the radiolarites of the Inthanon Zone were continental margin as shown by their geochemistry and deposited in deeper parts of small extensional basins with limited volcanism between long-lived, isolated carbonate platforms.

His 1981 PhD thesis published in 1982 laid the foundation of modern Thai stratigraphy. His highly cited papers on the tectonics of South East Asia, often with Professor Paul Vella, were based on Sangad's extraordinary first-hand knowledge of Thai geology which allowed him to draw the first reliable tectonic subdivisions of the whole country. Although controversial at the time, these tectonic subdivisions and hypotheses have since been accepted as generally correct in that the Shan-Thai Terrane (as part of Sibumasu) rifted from Australian crust in the early Permian, drifted and warmed as it crossed the Palaeotethyan Ocean and collided with the Indochina Terrane in the late Triassic. His stimulating palaeomagnetically constrained, combined palinspastic-palaeogeographic maps for the Permian to Cenozoic were well in advance at the time and have not been attempted again in the subsequent 40 years. His controversial later work, which attempted to explain the widespread, anomalous loess in northeast Thailand, the Australasian tektite strewn field, the fluvial deposits in Nakhon Ratchasima (Khorat) Province and their middle Pleistocene faunas and flora as the result of a cometary impact at 788 ka has received some support and some criticism but has nevertheless stimulated a considerable research and a lot of discussion. Over more than 50 years, Sangad made many major contributions to Thai geology, South East Asian tectonics and meteoritic research. His wit, wisdom and iconoclastic approach to earth and planetary science will be sorely missed by his numerous friends and colleagues.

Research paper thumbnail of The Truong Son, Loei-Phetchabun, and Kontum Terranes in Indochina: Provenance, Rifting, and Collisions

The aim of this review is to integrate numerous petrological studies with sedimentary, palaeontological, and provenance studies in order to construct a preliminary tectonic model which shows the terranes docked in the earliest Carboniferous (Truong Son with Loei-Phetchabun) and in the Permian (Kontum). The Kontum Terrane is characterized by Proterozoic magmatism, mid-Ordovician to Early Devonian granites, and Permian charnockites. Major carbonate platforms developed in the Givetian to earliest Tournaisian on Truong Son and from the Visean to mid-Permian across Truong Son and Loei-Phetchabun terranes. The Truong Son has Silurian granites and a Late Ordovician to Silurian magmatic arc along its southern and western borders caused by subduction of oceanic lithosphere, the remnants of which are now partially preserved in the Loei and Tamky sutures. A region to the east of the Loei Su...

Research paper thumbnail of Sinoceras chinense (Foord, 1888) in western Thailand: first identification outside China

Here, we document the first identification of S. chinense from the Kanchanaburi area, western Thailand. Upper part of the Tha Manao Formation containing S. chinense is extremely similar both faunally and lithologically to the coeval Pagoda Formation of South China. This identification from Thailand not only extends the palaeobiogeographic distribution of S. chinense, but also supports the dynamic palaeogeographic reconstruction of the peri-Gondwana Chinese terranes and Sibumasu from Middle to Late Ordovician.
