What is Tectonomagmatic Controls on Porphyry Mineralization about?

This document discusses a study of the Black Mountain porphyry copper-gold deposit in the Philippines. It details six intrusive phases identified in the area from oldest to youngest. Geochemical analysis of the rocks suggests mixing of mafic and felsic magmas. The mineralization is interpreted to have formed from underplating of a felsic magma chamber by an influx of mafic magma related to subduction of an aseismic ridge.
