Chapter 5 Porphyry Copper Deposits in China
2019Abstract Porphyry Cu deposits in China contain a total resource of ~47 million tonnes (Mt) Cu at average grades ranging mostly from 0.2 to 0.7% Cu (most <0.5% Cu), accounting for 42% of China’s Cu reserves. In terms of contained Cu, 14 Cu-rich porphyry deposits are classified as giant (≥2.0 Mt Cu), and 38 are classified as ...

Mapping porphyry copper deposits in the Philippines with IP
Geophysics, 1976Abstract The induced polarization (IP) method has played a very important role in the recent discovery of several new Philippine porphyry copper deposits. It was found, however, that the electrical response measured over different deposits can be extremely variable, even in a limited geographical area.Four main classes of response ...

Controls on copper and gold endowments of porphyry deposits
2020<p>Porphyry deposits are the major natural source of copper and a significant natural source of gold, which are essential metals for our society. Porphyry deposits form at convergent margins both during subduction (syn-subduction, Andean-type deposits) and in post-subduction to post-collision and extensional geodynamic settings ...

Regional Characteristics of Porphyry Copper Deposits of the Southwest
Economic Geology, 1974The largest and best studied concentration of porphyry-type deposits is the Southwest porphyry province in Arizona, southwestern New Mexico, and northern Sonora (Figure 1). Most of these deposits are in the 58 to 72 million-year-old range, with one 163 m.y. date and one 20 m.y. date.
