From a long-lived upper-crustal magma chamber to rapid porphyry copper emplacement : reading the geochemistry of zircon crystals at Bajo de la Alumbrera (NW Argentina).
Yannick Buret,Albrecht von Quadt,Christoph A. Heinrich,David Selby,Markus Wälle,Irena Peytcheva,Irena Peytcheva +6 more
TL;DR: In this article, the Bajo de la Alumbrera porphyry copper deposit in Northwest Argentina has been investigated using high-precision CA-ID-TIMS to constrain the duration of ore formation, including pre-, syn-and post-mineralisation porphyries.
Journal ArticleDOI
Solubility and partitioning behavior of Au, Cu, Ag and reduced S in magmas
TL;DR: In this paper, the solubility of sulfide-free and sulfur-bearing systems were studied with otherwise identical melt compositions to assess the relative effect of S on the solusability of these metals.
Journal ArticleDOI
Gold and copper in volatile saturated mafic to intermediate magmas: Solubilities, partitioning, and implications for ore deposit formation
TL;DR: In this paper, the solubility of Au and Cu in hydrous andesite melts was determined at 1000°C and 200MPa, and the results showed that the strong effect of reduced S and Cl on Au solubilities suggests dissolution mechanisms similar to those observed in magmatic volatiles.
Journal ArticleDOI
Performance characteristics of ultra-violet femtosecond laser ablation inductively coupled plasma mass spectrometry at ∼265 and ∼200 nm
TL;DR: In this article, the analytical figures of merit of ultra-violet femtosecond laser ablation inductively coupled plasma mass spectrometry (UV-fs-LA-ICP-MS) using the 3rd and 4th harmonics of Ti:Sapphire (∼265 and ∼200 nm, respectively) were explored.
Journal ArticleDOI
Fluid mixing forms basement-hosted Pb-Zn deposits: Insight from metal and halogen geochemistry of individual fluid inclusions
Tobias Fusswinkel,Thomas Wagner,Markus Wälle,Thomas Wenzel,Christoph A. Heinrich,Gregor Markl +5 more
TL;DR: Using laser ablation and inductively coupled plasma mass spectrometers, this paper determined the ore metal concentrations and the Cl/Br ratio in texturally constrained inclusion assemblages from a basement-hosted quartz-fluorite-barite-Pb-Zn vein system, demonstrating the transient and episodic nature of fluid mixing during mineral deposition.
