Metasomatic interactions between slab-derived melts and depleted mantle: Insights from xenoliths within Monglo adakite (Luzon arc, Philippines)
Michel Grégoire,Sébastien Jégo,René C. Maury,Mireille Polvé,Betchaida D. Payot,Rodolfo A. Tamayo,Graciano P. Yumul +6 more
TL;DR: In this article, an undeformed clinopyroxene characterized by convex-upwards REE pattern was found in the mantle section of an Early Cretaceous supra-subduction zone ophiolitic complex located within the Luzon arc crust.
Journal ArticleDOI
Controls on Gold Solubility in Arc Magmas: An Experimental Study at 1000°C and 4 kbar
TL;DR: In this paper, the solubility of gold at 4 kbar and 1000°C for three intermediate magmas (two adakites and one calc-alkaline composition) from the Philippines were determined.
Journal ArticleDOI
Geochemistry of Adakites from the Philippines: Constraints on Their Origins
Sébastien Jégo,René C. Maury,Mireille Polvé,Graciano P. Yumul,Hervé Bellon,Rodolfo A. Tamayo,Joseph Cotten +6 more
TL;DR: The authors identified in the Philippine Archipelago 230 samples of Late Miocene to Quaternary intermediate and evolved magmatic rocks or glasses, the compositions of which plot within the adakitic field defined by Defant and Drummond (1990) using Sr/Y ratios versus Y contents.
Journal ArticleDOI
Temporal geochemical evolution of Neogene magmatism in the Baguio gold-copper mining district (Northern Luzon, Philippines)
Mireille Polvé,René C. Maury,Sébastien Jégo,Hervé Bellon,Ahmed Margoum,Graciano P. Yumul,Betchaida D. Payot,Rodolfo A. Tamayo,Joseph Cotten +8 more
TL;DR: Baguio, in the Central Cordillera of Northern Luzon, is a district that displays porphyry copper and epithermal gold mineralization, associated with Early Miocene - Pliocene - Quaternary calc-alkaline and adakitic intrusions.
Journal ArticleDOI
The oceanic substratum of Northern Luzon: Evidence from xenoliths within Monglo adakite (the Philippines)
Betchaida D. Payot,Sébastien Jégo,René C. Maury,Mireille Polvé,Michel Grégoire,Georges Ceuleneer,Rodolfo A. Tamayo,Graciano P. Yumul,Hervé Bellon,Joseph Cotten +9 more
TL;DR: A suite of ultramafic and mafic xenoliths including spinel dunites showing typical mantle-related textures, mineral and bulk rock compositions, and serpentinites derived from them, amphibole-rich gabbros displaying incompatible element patterns similar to those of flat or moderately enriched back-arc basin basalt magmas, and amphibolite derived from metabasalts and/or metagabbros of identical affinity has been sampled.
