“…Moreover, the most typical occurrences of hornblende in all rock types should imply crystallization of a hydrous magma (Foden and Green, 1992;Best, 2003). The hydrous magmatic model of these volcanic rocks and dikes is also supported by the hydrous calc-alkaline magmatism reported by Fanka et al (2016Fanka et al ( , 2018 for the plutonic rocks in the Wang Nam Khiao area.…”

“…These depths (14-17 km) and the calculated temperature range of crystallization (861-927 • C) indicate geothermal gradient of about 50-65 • C/km which is comparable with an active continental margin (Rothstein and Manning, 2003;Annen et al, 2006;Chi and Reed, 2008). The combination of crystallization temperatures, pressure, and depths indicates that their original magmas should have stored and partially crystallized in the middle continental crust, which are the same provenance reported for plutonic rocks (e.g., hornblende granite, biotitehornblende granite, biotite granite) in the adjacent area (Peacock, 1993;Winter, 2001;Kelemen et al, 2003;Richards, 2003;Fanka et al, 2018).…”

“…Their ages were determined by zircon U-Pb dating such as of 230-254 Ma (Khositanont et al, 2008), 245.9-241.0 Ma (Kamvong et al, 2014), 245.9-258.6 Ma (Salam et al, 2014), 238-323 Ma (Zaw et al, 2007), and 314.6-349.6 Ma (Qian et al, 2015. In terms of the geochronology and geochemistry, this arc volcanism is comparable with the arc magmatism of plutonic rocks in Carboniferous to Triassic (Salam et al, 2014;Zaw et al, 2014;Fanka et al, 2016Fanka et al, , 2018.…”

“…In the study area, Permo-Triassic volcanic rocks have also been reported (Putthaphiban et al, 1989a,b;Kemlheg and Wichidchalermpong, 1992a,b) in association with a plutonic complex (Fanka, 2016;Fanka et al, 2016Fanka et al, , 2018. This complex includes hornblendite, hornblende gabbro, biotite granite, hornblende granite, and biotite-hornblende granite, defined as multiple arc magmatic events resulting from a Palaeo-Tethys subduction beneath Indochina Terrane during Late Carboniferous to Early Permian (zircon U-Pb ages of 314-285 Ma from biotite granite), Late Permian (zircon U-Pb ages of 253-257 Ma from hornblende granite and hornblende gabbro), and Middle Triassic (zircon U-Pb ages of 237 Ma from biotitehornblende granite) (Fanka et al, 2018).…”

Volcanic rocks and associated dikes have been exposed in Wang Nam Khiao area, Nakhon Ratchasima Province, northeastern Thailand where complex tectonic setting was reported. These volcanic rocks are classified as rhyolite, dacite, and andesite whereas dikes are also characterized by andesitic composition. These dikes clearly cut into the volcanic rocks and Late Permian hornblende granite in the adjacent area. Rhyolite and dacite are composed of abundant plagioclase and quartz whereas andesite and andesitic dike contain mainly plagioclase and hornblende with minor quartz. The volcanic rocks typically show plagioclase and hornblende phenocrysts embedded in fine-grained quartz and glass groundmass whereas dike rocks contain less glass matrix with more albitic laths. P-T conditions of crystallization are estimated, on the basis of Alin-hornblende geobarometry and hornblende geothermometry, at about 4.5-5.5 kbar, 861-927 • C and 4.8-5.5 kbar, 873-890 • C for the magma intrusions that fed volcanic rocks and andesitic dikes, respectively. Whole-rock geochemistry indicates that these rock suites are related to calc-alkaline hydrous magma. The enriched large-ion lithophile elements (LILE; e.g., Rb, Sr) and depleted high-field-strength elements (HFSE; e.g., Nb, Ce, Ti), with similar rare earth element (REE) patterns indicate arc magmatism. The results of this study are comparable with the continental arc magmatism along the Loei Fold Belt (LFB) as a consequence of the Late Permian Palaeo-Tethys subducted beneath Indochina Terrane.

Geochemical and zircon U-Pb geochronological constraints on late mesozoic Paleo-Pacific subduction-related volcanism in southern Vietnam

Late Mesozoic volcanic rocks comprising mainly basalt and basaltic-andesite to dacite occur in south-central Vietnam (Dalat zone) and to a lesser extent in southwestern Vietnam (Bay Nui area). Mineral and whole-rock chemistry indicate a calc-alkaline affinity for samples in the Dalat zone and a high-K calc-alkaline to shoshonitic affinity for rocks in the Bay Nui area. Mineral characteristics and variation diagrams of selected elements suggest that fractional crystallization dominated during magma differentiation. The Bay Nui volcanic rocks generally are more enriched in potassium and LILEs (large-ion lithophile elements) than volcanic rocks from the Dalat zone, which may indicate a more evolved nature or crustal assimilation. The similar chemical characteristics and eruption/emplacement age range of volcanic and plutonic rocks (ca. 90–110 Ma) of equal silica concentration indicate that the magma feeding the volcanic eruptions had the same source as that of the plutonic rocks. The observed mineral and whole-rock compositions with enrichment in LILEs, depletion in HFSEs (high field strength elements), and noticeably negative Nb, Ta, and Ti anomalies are characteristic for arc signatures. Zircon U-Pb geochronological data for the volcanic rocks indicate an age range of 95–105 Ma for the eruption. These geochemical and geochronological data link this Late Mesozoic volcanism with continental arc magmatism driven by the subduction of the Paleo-Pacific beneath eastern Indochina. Zircon xenocrysts with a likely magmatic origin cluster around 350 Ma and 250 Ma, indicating two earlier magmatic events most likely related to the subduction of the Paleo-Tethys beneath western Indochina and the subsequent Indosinian orogeny.
