Abstract The Puy-les-Vignes W deposit is an atypical wolframite-bearing hydrothermal breccia pipe hosted in migmatitic biotite-sillimanite gneisses in the northwestern French Massif Central. The deposit is characterized by volumetrically important tourmaline alteration allowing to investigate the fluid evolution of the ore-forming hydrothermal system. Four generations of hydrothermal tourmaline (Tur 1 to Tur 4) formed during pre-, syn-, and post-mineralization stages were identified based on det...

Abstract Although most of the methane on Earth is of biogenic origin, significant abiogenic methane has been identified in a variety of geological environments. Moreover, the presence of methane has been reported recently in fluid inclusions from a number of reduced porphyry deposits. The genesis of this methane, however, remains poorly understood. Here, we present results of a study of magma-exsolved CH4-rich aqueous fluid inclusions in the Seleteguole reduced porphyry–skarn Cu–Mo–Au deposit, N...

Abstract Felsic volcanic rocks are an important source for generating ion adsorption-type rare earth element (REE) resources. To better understand the supergene enrichment of REEs related to felsic volcanic rock weathering, this study conducted an investigation of Indosinian felsic volcanic rocks from Guangxi, southwest China, which have been subjected to deep weathering. The weathering has formed large areas of thick regolith with the potential to host ion adsorption-type REE mineralization. Th...

Abstract In minerals exploration, routine drilling is performed and the data logged from these drillholes, including lithological composition, assays, and downhole geophysical measurements such as natural gamma logs, are used to create geological interpretations of the strata within each drillhole. A 3D geological model can be created by identifying corresponding stratigraphic boundaries within multiple drillholes. These models can be used for understanding the formation and the mineral endowmen...

Abstract Fluid-zircon interaction in hydrothermal systems may provide key information on fluid characterization and ore precipitation. In this study, in situ analyses of Hf isotopes in zircon, combined with U–Pb ages and major and trace element data, provide new insights into fluid genesis at the Banxi antimony deposit. The zircons separated from typical quartz-stibnite ores and altered wall rocks have undergone fluid modification to different degrees, showing hydrothermal overprints in reflecte...

Abstract The Qi189 gold deposit is a recently discovered porphyry system in the Qiyugou Orefield, located in the northeastern Qinling Orogen along the southern margin of North China Craton. The orebodies are hosted in the porphyritic granite emplaced in the Taihua Supergroup. Three molybdenite and five pyrite samples from the ores yield Re–Os isochron ages of 129.5 ± 2.8 Ma and 127.5 ± 8.2 Ma, respectively, which are coincident with the zircon U−Pb age of the porphyritic granite within analytica...
Abstract This study focuses on the problem of Pb–Zn super-enrichment, and is based on a new conceptualisation of fluid–rock interactions→change in fluid properties → Pb–Zn hydrolysis→complex instability. Non-magmatic, epigenetic, hydrothermal Pb–Zn deposits in carbonates were used to perform Pb–Zn hydrolysis experiments under normal pressure. Lead–zinc fluid and carbonate interaction experiments, as well as Pb–Zn hydrolysis kinetics experiments during fluid–rock interaction, were performed analy...

Abstract The Tertiary palaeodrainage system in the Namibian calcrete-uranium province is deeply buried under a thick blanket of Cenozoic sediments (such as fluvial, alluvial and desert flash-flood terrace sediments, duricrusts and/or aeolian and fluvially reworked aeolian sands) and has no obvious surface expression, because of which, this province remains under-explored in spite of hosting the world’s largest calcrete-uranium deposit at Langer Heinrich. This paper presents first-pass bedrock ge...
