Geochronology and mineral geochemistry of apatite and zircon in the Hutouya Skarn deposit, East Kunlun Mountains, NW China

Hongying Qu, Julie V. Rowland, Jingwen Mao, Ivan Belousov (14731531) et autres

Consistency between apatite and zircon petrochronology supports the robustness in fingerprinting igneous processes in porphyry systems. In this paper, we systematically investigate geochronology and mineral chemistry of apatite and zircon hosted in syenogranite and monzogranite intrusive rocks in the large Hutouya skarn-type …

Tourmaline Mineral Chemistry: A Fertility Assessment and Vectoring Tool for Mineral Exploration in Magmatic-Hydrothermal Ore Systems

Wei Hong, Francisco Testa, David R. Cooke, Nathan Fox et autres

Abstract Tourmaline is a structurally and chemically complex hydrous borosilicate mineral that displays significant compositional variability in both major and trace elements. Its occurrence in a wide variety of ore-forming systems makes tourmaline a powerful provenance indicator because it can record the …

Geology and Isotope Geochemistry of the Wainaulo Cu-Au Porphyry Deposit, Namosi District, Fiji

Evan A. Orovan, David R. Cooke, Anthony C. Harris, Ben Ackerman et autres

The late Miocene, calc-alkalic, Wainaulo Cu-Au porphyry deposit of the Namosi district, Fiji, hosts distinct styles of alteration and mineralization that overlapped to produce a substantial porphyry Cu-Au resource. The early stages produced medium-grade Cu, low-grade Au and concentric calc-potassic to propylitic …

A Special Issue Devoted to Porphyry and Epithermal Deposits of the Southwest Pacific: An Introduction

Pete Hollings, Michael J. Baker, Evan A. Orovan, Marc L. Rinne

The southwest Pacific is host to a number of mineralization styles, including numerous world-class porphyry Cu-Au and epithermal Au-Ag deposits (Cooke et al., 2005; Garwin etal., 2005). The majority of the giant porphyry and epithermal Au and Cu deposits were formed within …
