Magmatic response to abrupt changes in geodynamic settings: Pliocene—Quaternary calc-alkaline and Nb-enriched lavas from Mindanao (Philippines)
135
TL;DR: The geochemical diversity of magmatic types in Mindanao is attributed to: 1) the highly heterogenous character of their mantle source, which contains variable amounts of metasomatic pargasite and phlogopite, and, possibly, an additional OIB component that could contribute to Nb enrichment of NEB as discussed by the authors.

Reaction between slab-derived melts and peridotite in the mantle wedge: experimental constraints at 3.8 GPa
TL;DR: In this paper, a set of experiments on natural, hydrous basalts at 1-4 GPa constrain the composition of "unadulterated" partial melts of eclogitized oceanic crust within downgoing lithospheric slabs in subduction zones, where these same adakite melts are allowed to infiltrate and react with an overlying layer of peridotite.

Petrology and geochemistry of Camiguin Island, southern Philippines: insights to the source of adakites and other lavas in a complex arc setting
TL;DR: Camiguin is a small volcanic island located 12 km north of Mindanao Island in southern Philippines as mentioned in this paper, which is the most likely source of Camiguin and most CMA magmas is the mantle wedge metasomatized by fluids dehydrated from a subducted slab.

The Archaean tonalite-trondhjemite-granodiorite (TTG) series is not an analogue of Cenozoic adakite
TL;DR: The tonalite-trondhjemite-granodiorite (TTG) series comprises silicic and sodic rocks that form a major component of preserved Archaean crust.

The Archaean High-Mg Diorite Suite: Links to Tonalite–Trondhjemite–Granodiorite Magmatism and Implications for Early Archaean Crustal Growth
TL;DR: The 2·95 Ga Pilbara high-Mg diorite suite intruded the central suites show no clear chemical evidence of having interacted with a part of the Archaean granite-greenstone terrain of the Pilbara mantle wedge, and on that basis are more likely to represent partial Craton, Western Australia, and shows many features typical of melts of basaltic lower crust rather than of subducted slab.
An overview of adakite petrogenesis
TL;DR: Adakite was originally defined to define silica-rich, high Sr/Y and La/Yb volcanic and plutonic rocks derived from melting of the basaltic portion of oceanic crust subducted beneath volcanic arcs as mentioned in this paper.

TL;DR: In this paper, the authors discussed the Neogene tectonic evolution of the Celebes-Sulu basins on the basis of representative seismic profiles, published industrial wells, and Leg 124 drilling results.
The mechanisms of petrogenesis of the Archaean continental crust—Comparison with modern processes
TL;DR: The petrographic and chemical composition of magmatic rocks generated during the Archaean appears to be different from that of post-Archaean rocks as mentioned in this paper. But the latter is not the case for the latter, as shown by the fact that after 2.5 Ga the role of these minerals in calc-alkaline magma genesis becomes progressively less important.

TL;DR: A data set comprising 110 spreading rates, 78 transform fault azimuths, and 142 earthquake slip vectors has been inverted to yield a new instantaneous plate motion model, designated Relative Motion 2 (RM2).
Drainage network analysis and tectonics of Mindanao, southern Philippines
TL;DR: A detailed study of the drainage pattern and its discontinuities in the Agusan-Davao and the Cotabato Basins when compared with field data, radar data and subsurface structures observed on seismic documents, enables a correlation of distant seismic lines and features existing on the basin edges as mentioned in this paper.
