Two recent articles on the ophiolites of Central Luzon and ophiolite associations in Northern Luzon offer new interpretations as to their genesis. Encarnacion and others (1993) propose a contemporaneous Eocene arc-back arc pair origin for the Zambales and Angat ophiolites td Central Luzon on the basis of zircon U-Pb geochronology. The other paper by Florendo (1994) postulates a Late Oligocene-Early Miocene intra-arc rifting in northern Luzon that led to the formation of new oceanic crust represented by the so-called Itogon Ophiolite in southern Central Cordillera These models are shown to suffer from substantial weaknesses in terms of stratigraphic incongruities and infirm assumptions Earlier studies clearly indicate that the Late Eocene sedimentary cover of the Zambales ophiolite (located on the western side of Central Luzon) was deposited in deep open ocean that is far from terrestial sources, which precludes a source that might correspond to the ancient Sierra Madre arc. On the eastern side of Central Luzon, the Cretaceous (Turonian-(Coniacian) dating of the Angat Ophiolite is well established on the basis of paleontologic dating of its sedimentary cover. The Eocene dating of silicic material presumably associated with the Angat Ophiolite would indicate two ophiolite bodies juxtaposed in a single north-south belt. Moreover, there is difficulty in identifying the volcanic and sedimentary carapace of the proposed Eocene ophiolite, which could be a subject for further research. As for the so-called Itogon Ophiolite, studies indicate that the plutons in Central Cordillera are made up mostly of Oligocene to Late Miocene diorites, and gabbros constitute a very small proportion. Two gabbro samples were dated 29 and 32 Ma, equivalent to Middle Oligocene (Maleterre, 1989), which is somewhat earlier than the supposed intra-arc rifting event. Furthermore, the Late Oligocene-Early Miocene Halfway Creek Formation of Florendo, which is supposed to represent the volcanic-sedimentary cover to the ltogon Ophiolite is actually equivalent to the Zigzag Formation, which is essentially a thick sequence of clastic rocks, with few if any intercalations of volcanic flows. However, a pre-Oligocene ophiolitic basement might exist in the Central Cordillera, and this could be a more fruitful subject of future research.
