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.

A Neogene history of mantle convective support beneath Borneo
TL;DR: In this paper, the authors explore the possible evolution of the Bornean landscape by extracting and modeling an inventory of 90 longitudinal river profiles and find that the divergence between observed and calculated river profiles is minimized by smoothly varying uplift rate as a function of space and time.

Gaëlle Prouteau,René C. Maury,Claude Rangin,Emmy Suparka,Hervé Bellon,M. Fubellier,J. Cotten +6 more
TL;DR: The Sintang adakites are coeval with the early stage of subduction of the Proto South China Sea Basin, at least in the westernmost half of the basin, according to recent models as mentioned in this paper.

Polybaric melting of a single mantle source during the Neogene Siverek phase of the Karacadağ Volcanic Complex, SE Turkey.
TL;DR: Siverek plateau basalts represent the Neogene activity of the Karacadag Volcanic Complex in southeast Turkey and can be divided into two groups based on incompatible element concentrations as discussed by the authors.

Late Cenozoic crustal extension and magmatism, southern Death Valley region, California

TL;DR: The late Cenozoic geologic history of the southern Death Valley region is characterized by coeval crustal extension and magmatism as discussed by the authors, and a tectonic-magmatic model that requires heat be transported into the crust by mantle-derived mafic magmas.
