Geology

The geology of Palawan is, in many ways, unlike other parts of the Philippines. The crust of northeast Palawan was derived from the southeast edge of the continental crust of China, part of the
Eurasian Plate The Eurasian Plate is a tectonic plate that includes most of the continent of Eurasia (a landmass consisting of the traditional continents of Europe and Asia), with the notable exceptions of the Indian subcontinent, the Arabian subcontinent and ...
. It is the exposed portion of a microcontinent that drifted southward with the opening of the South China Sea. This microcontinent also forms the shallow water north of Palawan in the Reed Bank- Dangerous Ground area of the southern South China Sea. Some of the oldest rocks of the Philippines are found in northeast Palawan (Permian-Carboniferous age). Southwest Palawan exposes primarily ophiolitic material (rocks derived from uplifted oceanic crust and mantle). This 34 Myr old (latest Eocene-earliest Oligocene) ophiolite appears to have been thrust upon the continental crust as well as the older, Cretaceous ophiolitic and sedimentary units. The transition from "oceanic"

in the southwest to "continental"-type rocks in the northeast occurs in the area of central Palawan around Ulugan Bay and the Sabang area. In the southern coasts of Ulugan Bay and Sabang Beach, are several exposures showing that the Palawan ophiolite has been thrust on to the continent-derived clastic rocks ("Sabang thrust"). The Palawan Trough is an area of deeper water adjacent to the north coast of Palawan in the South China Sea. The Palawan trough is thought to be due to downbending of the continental crust due to the weight of the ophiolite thrust sheet. Further north, around the Malampaya Sound area and up to the El Nido area, one finds older (Triassic-Jurassic) deep marine chert and limestone. The limestone forms spectacular karst terrain. These units are part of the microcontinent ("North Palawan Block") although they are deep marine rocks marginal to the continental crust. They were accreted to the Chinese continental crust in the Mesozoic at a time when an Andean-type subduction zone existed in southeast China. Intruding these rocks in central Palawan (Cleopatra's Needle area) and northern Palawan (Mount Capoas or Kapoas area) are young granite bodies (true granite to granodiorite). The Kapoas intrusion is of Miocene age (13-15 million years old based on zircon and monazite U-Pb dating). In the Taytay area of northern Palawan, a young basaltic cinder cone is another manifestation of young magmatic activity. The granitic magmatism and basaltic magmatism are both expressions of what has been identified as a widespread post-South China Sea spreading magmatism that has affected many areas around the South China Sea.

History

In April 2013, a fishing vessel loaded with illegally poached animals ran aground on a coral atoll off the coast of Palawan Island. In May 2014, armed forces chief of staff General Emmanuel T. Bautista said that Oyster Bay may be developed into a naval base with United States Navy support.
