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.

Cretaceous Crust in SW Borneo : Petrological, Geochemical and Geochronological Constraints from the Schwaner Mountains
TL;DR: In this article, it was shown that the Pinoh metamorphic group is Cretaceous rather than Palaeozoic as accepted up to now, and the Southern Schwaner Zone (SSZ) intrusives are granites and alkali-granites.

Preliminary geochemical and age data from postsubduction intrusive rocks, northwest Borneo
P. R. Williams,B. H. Harahap +1 more
TL;DR: A major phase of igneous activity of Late Oligocene to Early Miocene age affects West Kalimantan and Sarawak in northwest Borneo as discussed by the authors, which is related to deep crustal remelting and intrusion in a passive, postsubduction environment.

A Late Oligocene tectono-volcanic event in East Kalimantan and the implications for tectonics and sedimentation in Borneo
TL;DR: Aatite fission-track data from late Cretaceous sandstones indicate a period of rapid cooling in the late Oligocene as mentioned in this paper, initiated by a rapid temperature drop of over 40°C within c. 2 Ma might have been caused by increased denudation associated with tectonic movements.

A new upper Paleogene to Neogene stratigraphy for Sarawak and Labuan in northwestern Borneo: Paleogeography of the eastern Sundaland margin
Juliane Hennig-Breitfeld,H. Tim Breitfeld,Robert Hall,Marcelle K. BouDagher-Fadel,Matthew F. Thirlwall +4 more
TL;DR: In this article, the authors integrated fieldwork, U Pb zircon dating, biostratigraphy, and light and heavy mineral analyses to present a revised stratigraphy for the region as well as paleogeographic maps, including major paleo-river systems for the main sedimentary basins.

Adakites from collision‐modified lithosphere
Michael Haschke,Zvi Ben-Avraham +1 more
TL;DR: In this paper, the authors show that the adakites from Papua New Guinea (PNG) are associated with hot-slab melting and/or remelting of orogenic mafic underplate at convergent margins.
