Ophiolite is suggested to be formed in subduction events in oceanic basins. The occurrence of ophiolite is common in the Philippines. [34] Studying this ophiolite can help reveal the tectonic evolution of the region. [31] The majority of ophiolite in the Philippines was formed in the Cretaceous, with a minority formed in the Tertiary. [31]
The Mesoarchean (/ ˌ m iː z oʊ. ɑːr ˈ k iː ə n, ˌ m ɛ z oʊ-/ MEE-zoh-ar-KEE-ən, MEZ-oh-, also spelled Mesoarchaean) is a geologic era in the Archean Eon, spanning , which contains the first evidence of modern-style plate subduction and expansion of microbial life.
The Mesozoic Era [3] is the era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods.It is characterized by the dominance of gymnosperms such as cycads, ginkgoaceae and araucarian conifers, and of archosaurian reptiles such as the dinosaurs; a hot greenhouse climate; and the tectonic break-up of Pangaea.
The following is a list of known orogenies organised by continent, starting with the oldest in each. The headings are present-day continents, which may differ from the geography contemporary to the orogenies. Some orogenies encompass more than one continent and may have different names in each, and some very large orogenies include sub-orogenies.

The prehistory of the Philippines covers the events prior to the written history of what is now the Philippines.The current demarcation between this period and the early history of the Philippines is April 21, 900, which is the equivalent on the Proleptic Gregorian calendar for the date indicated on the Laguna Copperplate Inscription—the earliest known surviving written record to come from ...
