Intruding these stones in focal Palawan (Cleopatra's Needle region) and northern Palawan (Mount Capoas or Kapoas zone) are youthful rock bodies (genuine rock to granodiorite) of Miocene age (13-15 million years of age in view of zircon and monazite U-Pb dating).In the Taytay zone of northern Palawan, a youthful basaltic ash cone is another appearance of youthful magmatic movement. The granitic magmatism and basaltic magmatism are both articulations of what has been recognized as a far reaching post-South China Sea spreading magmatism that has influenced numerous zones around the South China Sea.
Structurally, Palawan with the Calamian Islands, is thought to be a north-east expansion of the Sunda Plate, in crash with the Philippine Mobile Belt at Mindoro.
