Summary:On the northern shore of Camarines Norte (S Luzon, Philippines) a tonalite/trondhjemite intrusion hosted by an ultramafic complex is exposed. The ultramafic complex is composed of metamorphic, depleted harzburgite and is considered as part of an ophiolite-sequence. The trondhjemites, which comprise the Paracale intrusion, may have formed by partial melting of tholeiitic materials under high water P. The magma may have been intruded as semi-solid plagioclase cumulate which resulted in a pronounced flow lamination of the rocks. (Authors' abstract) [A.W.H.]
