Mobilisation and Bioavailability of Arsenic Around Mesothermal Gold Deposits in a Semiarid Environment, Otago, New Zealand [PDF]
The Scientific World Journal, 2002 Arsenopyrite (FeAsS) is the principal arsenic (As) mineral in mineralised mesothermal veins (typically 5,000 mg/kg As) in southeastern New Zealand. Groundwater in contact with arsenopyrite-bearing rocks has elevated As concentrations (up to 0.1 mg/l ...

Geofluids, Volume 2022, Issue 1, 2022., 2022 The Roc Blanc Pb‐Zn‐Ag‐Au vein deposit is located in the NW of Marrakech, in the Central Jebilet massif. It is spatially related to Bramram‐Tabouchennt‐Bamega (BTB) granodioritic pluton (ca. 330 Ma) metamorphism aureole. The main veins hosted in black shales are oriented N‐S to NNW‐SSE. Pb‐Zn‐Ag‐Au ore is associated with quartz, chlorite, sericite, and

Archaeometry, Volume 63, Issue 1, Page 142-155, February 2021., 2021 The reasons why the Western Mediterranean, especially Carthage and Rome, resisted monetization relative to the Eastern Mediterranean are still unclear. We address this question by combining lead (Pb) and silver (Ag) isotope abundances in silver coinage from the Aegean, Magna Graecia, Carthage and Roman Republic. The clear relationships observed between

Geofluids, Volume 2021, Issue 1, 2021., 2021 A novel density model for computing quartz solubility in H2O‐CO2‐NaCl hydrothermal fluids applicable to wide ranges of temperature and pressure is proposed. Based on the models of Akinfiev and Diamond (2009) and Wei et al. (2012), the effective partial molar volume of water (VH2O∗) is replaced by the partial molar volume of water (V¯H2O) by ...
