TLDR
In this paper, geochronological and geochemical data for Neogene magmatism from West Sarawak were presented, showing that the geochemical diversity is consistent with the Bau and West SARawak Sintang suites representing mixtures of mafic, mantle-derived magma with felsic magma derived from remelting of hydrous basaltic rocks in the crust.About:

Lithosphere Erosion and Crustal Growth in Subduction Zones: Insights from Initiation of the Nascent East Philippine Arc
TL;DR: In this paper, the East Philippine Arc was studied and local variations in lithosphere thickness suggest that thinning is rapid and may be piecemeal, and the evolution of the arc lithosphere has been observed over time.

Mesozoic Paleo-Pacific Subduction Beneath SW Borneo: U-Pb Geochronology of the Schwaner Granitoids and the Pinoh Metamorphic Group
H. Tim Breitfeld,Lorin Davies,Robert Hall,Richard Armstrong,Marnie Forster,Gordon S. Lister,Matthew F. Thirlwall,Nathalie Grassineau,Juliane Hennig-Breitfeld,Marco W. A. van Hattum +9 more
TL;DR: In this article, the authors presented new geochemistry, zircon U-Pb and 40Ar/39Ar age data from igneous and metamorphic rocks from the Schwaner Mountains to investigate their tectono-magmatic histories.

Adakitic rocks at convergent plate boundaries: Compositions and petrogenesis
Qiang Wang,Qiang Wang,Lu-Lu Hao,Xiu-Zheng Zhang,Jin-Sheng Zhou,Jun Wang,Qi-Wei Li,Lin Ma,Long Zhang,Yue Qi,Gong-Jian Tang,Wei Dan,Jing-Jing Fan +12 more
TL;DR: In this article, the authors show that partial melting of mafic rocks can generate adakitic magmas under pressure, temperature, and hydrous conditions of 1.2-3.0 GPa, 800-1000°C, and 1.5-6.0 wt.% H2O.

A Triassic to Jurassic arc in north Borneo: Geochronology, geochemistry, and genesis of the Segama Valley Felsic Intrusions and the Sabah ophiolite
Alex Burton-Johnson,Colin G. Macpherson,Ian L. Millar,Martin J. Whitehouse,Chris J. Ottley,Geoff Nowell +5 more
TL;DR: The Segama Valley Felsic Intrusions (SVFI) of Sabah, north Borneo, shows them to be arc-derived tonalites; not windows or partial melts of a crystalline basement beneath Sabah as mentioned in this paper.

TL;DR: In this article, the Nyalau Formation (Biban sandstone Member and Upper Nyalua Member), Kakus Unit, and Merit-Pila Formation are divided into Oligocene to Lower Miocene sequences.

Patterns of intraplate volcanism controlled by asthenospheric shear
TL;DR: This article found a correlation between recent continental and oceanic intraplate volcanism and areas of the asthenosphere that are experiencing rapid shear due to mantle convection, and concluded that intra-plate eruptions are best explained by melting caused by shear flow within the astheosphere, whereas other localized processes are less important.

Late cretaceous to early tertiary structural elements of west Kalimantan
TL;DR: In this article, the authors define three domains with distinct geological and geophysical characteristics which were imprinted on the region by Early Cretaceous to Eocene convergent tectonic events.

Discordance of the U-Pb system in detrital zircons: implication for provenance studies of sedimentary rocks
TL;DR: In this paper, the authors compare the results of multiple ion probe intra-grain zircon analyses from a sample of psammite within the Dalradian Supergroup of Scotland with a data set from the same sample based on single grain ion probe analysis using various filtering methods.

Palaeomagnetic data and radiometric ages from the Cretaceous of West Kalimantan (Borneo), and their significance in interpreting regional structure
TL;DR: Palaeomagnetic measurements on thirtynine samples of dyke rocks, lavas, tuffs, granites, hornfels and metatuff, all believed to be late Cretaceous, yield a mean palaeomalagnetic pole at 21°E 41°N, and a palaeolatitude for West Kalimantan of 0° as discussed by the authors.

Delayed partial melting of subduction-modified mantle in papua new guinea
TL;DR: In this article, the late Cainozoic volcanoes in Papua New Guinea were assigned to nine volcanic provinces, seven of which are related to arc-trench systems. But the three other provinces do not appear to be related to late Mesozoic subduction; in these, the rocks are characterised by higher LILE contents and higher 87 Sr/ 86 Sr values than are rocks from the other provinces, and their chondritenormalized REE patterns are more strongly fractionated ([La/Yb]e.f.
