Two new cases of association of adakites with ‘normal’ island arc lavas and transitional adakites are recognized in the islands of Batan and Negros in northern and central Philippines, respectively. The Batan lavas are related to the subduction o

Pliocene–Quaternary adakites and spatially and temporally associated niobium-enriched basalts (the latter thought to be derived by melting of slab melt-metasomatized mantle) from the Philippine island arcs have been selected for analysis of high fi

The Victoria gold deposit is a low-sulfidation style epithermal carbonate-base metal gold deposit discovered in 1995 in the Mankayan mineral district, northern Luzon, Philippines. It occurs just south of a high-sulfidation copper-gold orebody (Lepant

Central Mindanao was the locus of a Pliocene (4–5 Ma old) arc–arc collision event followed by basaltic to dacitic magmatism starting at 2.3 Ma, representing the most voluminous volcanic field in the Philippines. Lava compositions range from calc-

Adakites are intermediate or acidic volcanic and plutonic rocks which derive from partial melting of subducted oceanic crust when the subducting slab is young (< 20 Ma) and hot, and at the start and the end of subduction. In the Philippines, most of

A set of 230 igneous rock samples from Leyte and Mindanao (Philippines) has beenstudied for their major and trace element chemistry, mineralogy and geochronology (40K-40Ar dating). Several volcanic sectors have been distinguished according to their g

The Pliocene-Pleistocene magmatic activity of the ^amboanga arc is linked to the southward subduction of the Oligocene-Miocene Sulu Sea back-arc basin along the Sulu Trench. The magmatic products include small amounts ofadakites datedfrom 3-8 to 0-7

Mindanao, the largest island in the southern Philippine archipelago, is a composite of at least two terranes; one with Eurasian affinity (western Mindanao) and the other belonging to the Philippine Mobile Belt (eastern Mindanao), of Philippine Sea pl

Holes were drilled at three Sites in the Sulu Sea on Ocean Drilling Program Leg 124. Site 768 lies in the deeper part of the SE sub-basin and Sites 769 and 771 lie on the flanks of the Cagayan ridge. The results indicate that the Sulu Basin originate

Leg 124 of the Ocean Drilling Project drilled Sites 767 and 770 in the northern Celebes Sea, reaching late middle Eocene basaltic basement at both sites. Major shifts in sediment provenance record the changing tectonic setting of the basin. From late
