[1] It is considered one of the best-preserved and most studied ophiolites , offering valuable insights into the formation and evolution of oceanic crust and the ...
Major physiographic elements of the Philippine Mobile Belt Puerto Princesa Subterranean River National Park marker describing the geologic history of the Philippines. In the geology of the Philippines, the Philippine Mobile Belt is a complex portion of the tectonic boundary between the Eurasian plate and the Philippine Sea plate, comprising most of the country of the Philippines.
The Masungi Georeserve is a conservation area in the Philippines situated in the southern Sierra Madre range in Baras. It centers on the geological formations of Masungi Rock, at an elevation of 640 metres (2,100 ft). [1] In 1993, the Masungi Rock and its vicinity was proposed to be declared as a Strict Nature Reserve and Wildlife Sanctuary.

These two tectonic features thus correlate to a similar time of development. The formation of the PFZ was a result of two stages. The first stage began at ~10 Ma, when the northern segments of the PFZ developed due to the convergence of the China Sea Crust underneath the nearby Manila Trench. The lack of accretionary prism at the Philippine ...
