Bulk rock geochemistry and SWIR reflectance spectroscopy are widely used by companies for rapid and cost-effective exploration of volcanic-hosted massive sulfide (VHMS) deposits. However, few studies have integrated bulk-rock geochemistry with hyperspectral reflectance spectroscopy in greenstone belts that have undergone high-grade metamorphism. Here we present an extensive dataset combining bulk-rock

Sedimentary Fe deposits are both scientifically and economically important. As a major ore mineral of these deposits, siderite is generally assumed to have been formed via diagenetic transformation of other Fe-bearing minerals. The Devonian Daxigou sedimentary siderite deposit, Central China, contains ca. 500 Mt Fe with an average ore grade of ca. 30 wt% FeOT but is poorly known in the literature.

The Gondpipri layered mafic–ultramafic intrusion at the western margin of the Bastar Craton in Central Indiacomprises leucogabbro, gabbronorite, and websterite. The intrusion hosts both magmatic and hydrothermal Ni-platinum group element (PGE)mineralisation. In this study, we use in-situ measured trace element composition of pyrite and magnetite and zircon U–Pb geochronology to elucidate hydrothermal

Epithermal precious metal deposits are uncommon within the Archean rock record, as are detailed descriptions of their associated features and modes of formation. The Vent prospect is a Neoarchean Au–Ag occurrence within the Eastern Wabigoon Subprovince of the Superior Province in Ontario. It is hosted by aphyric, and quartz ± feldspar-porphyritic aphanitic dacitic flows that show remnants of spine-like

We provide timestamps for the major zinc-lead (Zn-Pb) Mississippi Valley-type Black Angel deposit (Greenland) based on new pyrite rhenium-osmium (Re-Os) isotope geochemistry data: (1) a Re-Os isochron age 1,884 ± 35 million years ago (Ma – 2σ, 1.8%) for subhedral pyrite cemented by sphalerite ± galena in dolomitized clean limestone, and, (2) a Re-Os model age 1,828 ± 16 Ma (2σ, 0.9%) for epigenetic

Porphyry deposits of the Cu-Mo-Au-Re metal spectrum mainly occur in arc settings, but only some segments of the same arc host significant metal resources. The factors controlling the variable metal endowment in magmatic arcs remain unclear. Here, we conducted zircon U-Pb age, trace element, and Hg isotope studies on the ore-bearing (i.e., fertile) and coeval barren granitic rocks from the Upper Triassic

Tungsten enrichment during the formation of giant W deposits is thought to be related to magmatic and hydrothermal processes. However, the mechanisms of W enrichment and their role in controlling ore formation remain unclear. Zircon is a ubiquitous accessory mineral that can provide a record of the physicochemical conditions during mineralization. Dahutang in South China is a giant W deposit (1.89
