“…These granitoid provinces are commonly considered to be the products of Permian to Cenozoic magmatic events and play an important role in the tectonic reconstruction of western SE Asia. There are an increasing number of studies on granitoids in western SE Asia examining emplacement time, magma source, formation mechanism and tectonic implication (Gardiner, Searle, Robb, & Morley, 2015; Gasparon & Varne, 1995; Jamil, Ghani, Zaw, Osman, & Quek, 2016; Jiang, Li, Jiang, Wang, & Wei, 2017; Ng, Chung, et al, 2015; Ng, Whitehouse, et al, 2015; Qian et al, 2017; Queka et al, 2017; Schwartz, Rajah, Askury, Putthapiban, & Djaswadi, 1995). However, granitoids in Sumatra, a large island proximal to Malay Peninsula to the northeast, have long been ignored in recent years.…”

Late Triassic A-type granites are identified in this study in Sarudik, SW Sumatra. We present new data on zircon U-Pb geochronology, whole-rock major and trace elements and Sr-Nd-Hf isotope geochemistry, aiming to study their petrogenesis and tectonic implications. LA-ICP-MS U-Pb dating of zircon separated from one biotite monzogranite sample yields a concordia age of 222.6 ±1.0 Ma, indicating a Late Triassic magmatic event. The studied granites are classified as weakly peralumious, high-K calc-alkaline granites. They exhibit high SiO 2 , K 2 O + Na 2 O, FeO/(FeO + MgO) and Ga/Al ratios and low Al 2 O 3 , CaO, MgO, P 2 O 5 and TiO 2 contents, with enrichment of Rb, Th and U and depletion of Ba, Sr, P and Eu, showing the features of A-type granites. The granites have zircon ε Hf (t) values from −4.6 to −0.4 and wholerock ε Nd (t) values from −5.51 to −4.98, with Mesoproterozoic T DM2 ages (1278-1544 Ma) for both Hf and Nd isotopes. Geochemical and isotopic data suggest that the source of these A-type granites is the Mesoproterozoic continental crust, without significant incorporation of mantle-derived component, and their formation is controlled by subsequent fractional crystallization. The Sarudik A-type granites are further assigned to A2-type formed in post-collisional environment. Combined with previous knowledge on the western SE Asia tectonic evolution, we conclude that the formation of the Late Triassic A-type granites is related to the post-collisional extension induced by the crustal thickening, gravitational collapse, and asthenosphere upwelling following the collision between the Sibumasu and the

“…The closing of the Eastern Palaeo-Tethys Ocean was due to the Late Palaeozoic to Early Mesozoic subduction under the Indochina-East Malaya Block and subsequent collision with Sibumasu Terrane 11,12,15,16 . The collision formed the Late Triassic (201-227 Ma) Main Range Granite Province, which covers most of Western Peninsular Malaysia [16][17][18][19][20][21][22][23] .…”

Absolute Age Evidence of Early to Middle Ordovician Volcanism in Peninsular Malaysia

Evidence of Early Palaeozoic volcanism inPeninsular Malaysia is largely represented by felsic Gerik-Dinding meta-volcanic rocks; however, reliable absolute ages for the meta-volcanic rocks are still lacking. This restricts correlation of these meta-volcanic rocks with other Early Palaeozoic East Gondwana Proto-Tethys margin tectonic elements identified in the evolution of Southeast Asia. Here, we report petrographic data and zircon U-Pb age of the Gerik-Dinding metavolcanic rocks. Zircons from three Gerik-Dinding meta-volcanic rock samples yield Early to Middle Ordovician weighted mean 206 Pb/ 238 U ages between 480 and 460 Ma. The formation age of the meta-volcanic rocks coincides with the post-collision stage from the final amalgamation of Asian micro-continental fragments with the East Gondwana Proto-Tethys margin. Tectonic processes such as lithospheric delamination during the post-collision period could have induced the hot asthenosphere to underplate the continental crust and trigger crustal anatexis. With these findings, the Early Palaeozoic tectonic history of Peninsular Malaysia needs careful review.

“…The material used to make Labu Sayong is a reddish alluvial clay excavated from pits on terraces of the Perak River further south, close to the centers of manufacture. In the recent past (~ 2014), relatively pure volcanic ash from the vicinity of Pulau Kemiri, several kilometers upstream, was blended with the locally sourced clay (Hashim, 2014) The alluvial sediments of the Perak River Basin is underlain by Bintang and Main Range Granites (Chesner et al, 1991;Mokhtar, 2009;Smith et al, 2011;Quek et al, 2017), the alluvium is thought to be derived from the weathering and erosion of the granites. Upon examination, this material contains varying proportions of volcanic glass shards in addition to clay minerals and quartz.…”

Clay used in the manufacture of the artisanal drinking water vessels known as Labu Sayong has been found to contain fine volcanic ash from the Young Toba Tuff (YTT) eruption. Thick distal YTT ash deposits have been found in the Lenggong-Kuala Kangsar area. Reworking, transportation and redeposition of the ash has caused it to be mixed with alluvial clay, silt and sand. The material used in the manufacture of Labu Sayong is coarse compared to that used in the manufacture of other ceramics, since the vessels must be slightly porous and permeable to water for the purpose of evaporative cooling. In actual use the vessel comes with a supporting dish which catches condensation and seepage. However, the dish lacks strength to support the weight of the water stored in the vessels. This study evaluates the effect of the addition of three substances - rice husk, grog and pure volcanic ash into the natural clay. Even though the addition of grog and volcanic ash does not affect the shrinkage during dehydroxilation, shrinking starts to happen at a lower temperature with the ash. Large amount of organic material is burned with the rice husk leading to very porous materials. Volcanic ash is found to be a favourable additive to add to the vessel strength without compromising on the porosity.
