Many Third World and developing countries rely mainly on the utilisation of their natural resources to sustain their economic development. In the Philippines in particular, the exploitation of mineral resources has traditionally been a significant component of the Philippine economy (Domingo, 1993).

This volume of the Geology of the Philippines, Second Edition comes at an opportune time when the Philippines has become once more  a beehive of activities by geologists owing to the efforts of government to promote the revitalization of the mining industry. This edition is a timely reference material that gives the reader an overview of the geology of the Philippines, as well as the stratigraphic make-up of local areas.

The Philippine Mineral Reporting Code (PMRC), or the “Code” sets out minimumstandards, recommendations, and guidelines for Public Reporting in thePhilippines of Exploration Results, Mineral Resources, and Mineral Reserves.
