ABSTRACT

 

The Paracale District, Camarines Norte, Philippines, is noted for its production of gold and iron. Features which influenced the localization of both commercial and non-commercial mineral deposits are described.

A study of the district reveals that mineral deposits tend to be distributed zonally with respect to the Paracale Stock. Three zones are recognized: (1) a gold zone, (2) an iron belt, and (3) a base metal belt. The gold zone lies within the Paracale granodiorite stock. The iron and base metal belts roughly parallel the southern contact of the Paracale Stock, and arc associated with this stock only in that the dynamics of intrusion of the stock initiated the folding and faulting that tended to localize the iron and base metal mineralization. Subsequent intrusion of small dioritic and syenitic stocks, dikes, and sills directly influenced the localisation of the iron and base metal mineralization.
