The Philippine Archipelago is geologically part of the Philippine Mobile Belt located between the Philippine Sea Plate, the South China Sea Basin of the Eurasian Plate, and the Sunda Plate.
22.
It is on the southeast side of Luzon, close to the Philippine Trench, which is the convergent boundary where the Philippine Sea Plate is driven under the Philippine Mobile Belt.
23.
To the south the Philippine Mobile Belt terminates in the Molucca Sea Collision Zone, which is itself part of the elongated zone of convergence extending north through the Philippines into Taiwan.
24.
The Philippine Trench ( also called the Mindanao Trench ) is a submarine trench in length found directly east of the Philippine Mobile Belt and is the result of a collision of tectonic plates.
25.
The West African Craton stretches from the Little Atlas mountains of Morocco to the Gulf of Guinea, and is bounded by mobile belts of much younger rocks to the north, east and west.
26.
Plate locking between the Sunda Plate and Luzon is about 1 % coupled, almost unlocked as determined by elastic block models, suggesting that the trench absorbs the Philippine Mobile Belt-Eurasian Plate convergence.
27.
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.
28.
To the west, the Philippine Sea Plate subducts under the Philippine Mobile Belt at the Philippine Trench and the East Luzon Trench . ( The adjacent rendition of Prof . Peter Bird's map is inaccurate in this respect .)
29.
Together with Sulu Archipelago, Sabah, and South China Sea, El Nido, being part of Palawan, is located in the tectonically active and seismically active Sunda Plate, a plate that is entirely separate from the Philippine Mobile Belt to which the rest of the Philippines belongs.

Proterozoic greenstones occur sandwiched between the Pilbara and Yilgarn cratons in Australia, and adjoining the Gawler Craton and within the extensive Proterozoic mobile belts of Australia, within West Africa, throughout the metamorphic complexes surrounding the Archaean core of Madagascar; the eastern United States, northern Canada and northern Scandinavia.
