Geochemical Evolution at White Island, New Zealand
… of the environment associated with formation of porphyry copper deposits. White Island has only been active for about 10 Ka and, as such, is thought to be an ideal location to study early magmatic processes associated with formation of porphyry copper deposits. In this study, the geochemistry of …

Magmatic evolution of the southern Centinela district, northern Chile: insights from PGE geochemistry and zircon fertility tools
Copper is one of the most widely used metals in our society and it is essential for a broad range of applications. Globally, nearly three quarters of this metal is sourced from porphyry copper deposits. For this reason, is important to understand the processes that control their formation. Recent …

Data-driven approaches towards understanding trace metal and magmatic processes in arc volcanoes, with applications to Java, Indonesia
… petrological processes favor the enrichment of copper and the optimization of ore-forming potential in a magma? These global insights are complemented by a detailed petrological study of Mount Slamet volcano, Java, Indonesia, infused with computational advances in machine-learning. Java has 45 …

Silicate Melt Inclusions in Igneous Petrogenesis
… there are few studies of such inclusions from porphyry copper systems. A melt inclusion forms when magma is trapped in a growing phenocryst. If a phenocryst is able to preserve the original parent magma, then accurate information can be obtained for ancient volcanic systems. In recent igneous …

Early Laramide Magmatism in Southern Arizona U-Pb Geochronology of Key Igneous Units and Implications for the Timing of Regional Porphyry Copper Mineralization
… in the emplacement of numerous productive (porphyry copper) deposits, associated Ag-base metal deposits, and barren intrusive units. The timing of these events has been loosely constrained by early K-Ar ages and cross-cutting field relationships; in many districts early Laramide volcanic …

Magmatic and volcanic processing of volatile and chalcophile elements
… including several chalcophile elements such as copper, selenium, and silver. Copper in particular is essential – it is a key component in wind and solar technologies, as well as energy storage systems, all of which are central to the energy transition. However, with existing ore grades declining …
