Abstract Papua New Guinea and the Solomon Islands are in one of the most prospective
regions for intrusion-related mineral deposits. However, because of the tectonic complexity …

Arc magmas globally are H2O-Cl-S–rich and moderately oxidized (ΔFMQ=+ 1 to+ 2) relative
to most other mantle-derived magmas (ΔFMQ≤ 0). Their relatively high oxidation state limits …

There is commonly a close spatial relation between porphyry Cu (±Au) and high-sulfidation
epithermal Cu-Au deposits throughout the world, although a genetic association has not …

A balanced text that bridges the gap between introductory petrography-oriented texts and
the more advanced texts that have a thermodynamic and/or chemical approach. Well …

This textbook on ore geology is for second and third year undergraduates and closely
parallels the undergraduate course given in this subject at England's University of Leicester …

Geologic field relationships combined with spatially resolved geochemistry and high-
precision U-Pb geochronology of zircons allow quantification of magmatic processes …

Sulphide and flotation concentrates from 33 porphyry copper deposits have been
investigated for platinum-group elements (PGE), Au, Cu and platinum-group minerals …

Whether multiple mineralization styles in porphyry deposits are the result of one or multiple
pulses of magmatism is unknown. In this paper, we present new age and geochemical data …

The Maramuni arc represents the only continuous record of the tectonic evolution of Papua
New Guinea during the Miocene, and hence provides an opportunity to gain insight into …

Abstract The Takidani Granodiorite is a pluton (13 x 4 km) situated along a major axis of the
Japan Alps that was intruded into late Pliocene age (2.4 Ma) volcanic rocks. Rb-Sr, K-Ar …
