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 Qinzhou‐Hangzhou metallogenic belt is an important polymetallic (Cu, Mo, W, Sn, Pb, Zn, Au, and Ag) belt in South China. The Xinmin polymetallic deposit is located in the southwestern segment of this belt, which ore bodies hosted in the contact zone of granite and Lower Devonian sedimentary strata and in the structure fractured zone within the strata ...

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 ...

Mineralogy and distribution of critical elements in the Sn–W–Pb–Ag–Zn Huanuni deposit, Bolivia [PDF]
, 2019 The polymetallic Huanuni deposit, a world-class tin deposit, is part of the Bolivian tin belt. As a likely case for a “mesothermal” or transitional deposit between epithermal and porphyry Sn types (or shallow porphyry Sn), it represents a case that ...

A review of the mesothermal gold deposits of the Meguma Group, Nova Scotia, Canada
Ore Geology Reviews, 1998 Abstract The gold province of the Meguma Terrane in Nova Scotia contains several classic examples of turbidite-hosted mesothermal gold deposits. There are over 300 gold occurrences and deposits hosted by the Cambro–Ordovician Meguma group rocks in southern Nova Scotia, Canada.
