| Provenance and tectonic setting of the Klondyke and ZigzagFormations: Implications on the oceanic to island arc evolutionof the Baguio Mineral District, Philippine |
| Petrographic and geochemical studies were made on the sedimentary units of the Baguio Mineral Dis-trict and its adjacent areas. These analyses are par-ticularly useful in providing clues on the geologic evolution not just of Northern Luzon but of the Phil-ippine island arc system as well.
Results on the petrography of the clastic rock units of the Baguio Mineral District reveal that the Zigzag Formation samples contain more quartz but less plagioclase compared to samples of the Klondyke, Amlang and Cataguintingan formations. It is also noted that lithic fragments are more abundant in the Klondyke Formation sandstone samples. |
