The combination of zircon U-Pb geochronology, trace element geochemistry and Hf isotopes have become an extremely popular tool for provenance studies paleogeographic reconstructions. Here, we present integrated study U-Pb-Hf isotopic geochemical constraints from two basement complexes in western Luzon, Philippines. Basement rocks these areas offer insights into the geologic tectonic development northern Philippines its correlation with adjacent southeast Asia. We also include Mesozoic Taiwan...
Only limited orogens show preserved markers of collision initiation, so that this specific stage is generally not integrated in plate tectonic models attempting to reconstruct their evolution. In SE Asia, the case Philippine Mobile Belt Philippines and Taiwan, but basement elements involved growth belt are fully comprehend construction region.The geological evolution Philippine-Taiwan region includes extensional, compressional transform settings overlapping space time since Late Cretaceous....
The interaction between migrating melts and the upper mantle largely affects composition of ascending melt residual peridotites. In island arcs, melt-rock interactions products which involved highly depleted peridotites are still undocumented despite their petrological importance. this contribution, petrographic geochemical signatures refractory refertilized comprising section southern Palawan Ophiolite, Philippines investigated. dominantly comprised spinel harzburgites with minor dunite...
The mantle section of the central Palawan Ophiolite (CPO) in western Philippines is dominantly composed dunites and harzburgites. Basal lherzolites harzburgites juxtaposed with metamorphic sole CPO are also exposed within vicinity Ulugan Bay, Puerto Princesa. These basal peridotites provide novel information regarding processes transpiring upper during evolution this preserved oceanic lithosphere. Nasuduan lherzolite characterized by low Cr# spinel high concentrations REEs clinopyroxenes....
