TLDR
In this article, the authors analyzed sulfide samples from 27 black smoker samples derived from three different seafloor hydrothermal fields: the ultramafic-hosted Logatchev Hydrothermal field on the Mid-Atlantic Ridge, the basaltic-based Turtle Pits field and the felsic hosted PACMANUS field in the Manus basin (Papua New Guinea).About:

Trace element systematics of pyrite from submarine hydrothermal vents
TL;DR: In this paper, minor and trace element contents in pyrite from active and inactive submarine hydrothermal vent fields at different plate-tectonic settings including the Indian and mid-Atlantic Ridges, the Tonga-Kermadec intra-oceanic arc, the Lau back-arc and the central Okinawa Trough were investigated.

A review of Te and Se systematics in hydrothermal pyrite from precious metal deposits: Insights into ore-forming processes
TL;DR: In this paper, the authors compare the Te and Se contents of pyrite from a global dataset of Carlin-type, orogenic Au, and porphyry-epithermal deposits to investigate: (1) the potential of Pyrite to be a major repository for these elements; and (2) whether Te and se provide insights into key ore-forming processes.

Trace Element Analysis of Minerals in Magmatic-Hydrothermal Ores by Laser Ablation Inductively-Coupled Plasma Mass Spectrometry: Approaches and Opportunities
TL;DR: Laser ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) has rapidly established itself as the method of choice for generation of multi-element datasets for specific minerals, with broad applications in Earth science as mentioned in this paper.
Journal ArticleDOI
Geochemical and micro-textural fingerprints of boiling in pyrite
TL;DR: In this article, the authors examined pyrite geochemical and micro-textural features and relate these results to pyritic-forming processes at the active Cerro Pabellon Geothermal System (CPGS) in the Altiplano of the northern Chile.

Trace elements in hydrothermal chalcopyrite
TL;DR: Chalcopyrite is generally a poor host for most elements considered harmful or unwanted in the smelting of Cu, suggesting it is rarely a significant contributor to the overall content of such elements in copper concentrates as mentioned in this paper.

The composition of the Earth
William F. McDonough,Shen-Su Sun +1 more
TL;DR: In this paper, the authors compared the relative abundances of the refractory elements in carbonaceous, ordinary, and enstatite chondritic meteorites and found that the most consistent composition of the Earth's core is derived from the seismic profile and its interpretation, compared with primitive meteorites, and chemical and petrological models of peridotite-basalt melting relationships.

Thermodynamics of hydrothermal systems at elevated temperatures and pressures
TL;DR: In this article, sufficient thermodynamic data are available to permit calculation of equilibrium constants for a large number of hydrothermal reactions, where the calculations involve entropy estimates, application of average heat capacities, and/or assumptions concerning the temperature dependence of thermodynamic variables and the relative importance of electrostatic and non-electrostatic interaction among the species.

Gold and Trace Element Zonation in Pyrite Using a Laser Imaging Technique: Implications for the Timing of Gold in Orogenic and Carlin-Style Sediment-Hosted Deposits
Ross R. Large,Leonid V. Danyushevsky,Chris Hollit,Valeriy V. Maslennikov,Sebastien Meffre,Sarah Gilbert,Stuart W. Bull,RJ Scott,Poul Emsbo,Helen Thomas,Bob Singh,Jeffrey G Foster +11 more
TL;DR: The early enrichment of gold in arsenic-bearing syngenetic to diagenetic pyrite, within black shale facies of sedimentary basins, is proposed as a critical requirement for the later development of Carlin-style and orogenic gold deposits in sedimentary environments as discussed by the authors.

Composition of the Earth
TL;DR: In this paper, the cosmic abundances and the composition of the nebula from which the planets accreted have been revised based on chondritic values, which imply that the mantle could contain about 15 weight percent FeO and more CaMgSi_2O_6 than has been supposed.
