The Zambales ophiolite of western Luzon, Philippines, exposes a typical succession of basalt flows, diabasic dikes, gabbro and tectonized harzburgite. The age established by limiting strata is late Eocene. Lack of evidence of thrust faulting and the general domal disposition of the lithologie units indicate that the ophiolitic rocks are exposed by uplift.

August 17, 2023 by Mcnair, B. Basalt is a hard, fine-grained, dark-colored volcanic or extrusive rock. It has primarily calcium-rich plagioclase and augite. Also, it may have minor amounts of other minerals like quartz, olivine, foids, alkali feldspar, biotite, and amphibole. This rock is undoubtedly popular, only rivaled by granite.
