Abstract Unravelling the genesis of metamorphosed mineral deposits can be complicated due to difficulties in separating between primary features and that formed during metamorphic overprint. Such uncertainty exists for stratabound dolomite- skarn-hosted Zn-Pb-Ag sulfide 1.89 Ga rocks Bergslagen lithotectonic unit (BLU) Sweden, where a metasomatic vs. regional origin skarns has long been discuss...

The San Manuel magnesian skarn is an iron deposit hosted in dolomitic marbles from a tectonic slice imbricated within the Ronda peridotites, westernmost part of Betic Cordillera, Spain. According to dominant mineral assemblage, subdivided into three different zones, (1) forsterite ± calcite skarn, (2) chlorite serpentine and (3) Ca-amphibole skarn. main ore ? 2.5 m thick, massive body situated ...

Garnet is the most common alteration mineral in skarn-type deposits, and geochronological research on it can limit mineralization age. The Longwan Pb–Zn deposit, situated within Fozichong ore field Guangxi, lacks precise data, limiting in-depth comprehension of its genesis tectonic setting. This study employs LA-ICP-MS U–Pb dating garnets developed skarn orebody zircons associated granitic porp...

Abstract New mineralogical, geochemical, and geochronological data are presented for the Island Dam prospect, Olympic Cu-Au Province, South Australia. Skarn assemblages comprising actinolite/phlogopite + K-feldspar magnetite suggest presence of calcareous protoliths at indicate high-temperature alkali-calcic alteration in early stages IOCG mineralization, as seen other deposits region. Dating l...

Jiama is a super-large porphyry copper–polymetallic deposit located in the Gangdese metallogenic belt of southern Tibet. The consists combination polymetallic skarn, Cu–Mo mineralization at contact between Porphyry and hornfels, distal Au fault. current metal reserves are 7.4 Mt Cu, 0.6 Mo, 1.8 Pb–Zn, 6.65 Moz Au, 360.32 Ag, with skarn to porphyry–hornfels host-rock ratio ~3:1. Based on detaile...

We report the iron (n = 13), copper sulfur 25) and lead 31) isotope compositions of mineralized samples from porphyry, skarn epithermal mineralization in Yenice region that lies east Biga Peninsula, Turkey. The vast majority isotopic data were analyzed world-class Arapuçandere Pb-Zn-Cu (Ag-Au) deposit is one best example intermediate sulfidation deposits within Serbo-Macedonian-Rhodope metallog...

Abstract Magnetite is a common mineral in the Paleoproterozoic Stollberg Zn–Pb–Ag plus magnetite ore field (~6.6 Mt of production), which occurs 1.9 Ga metamorphosed felsic and mafic rocks. Mineralisation at consists bodies massive to semi-massive sphalerite–galena pyrrhotite (with subordinate pyrite, chalcopyrite, arsenopyrite magnetite) hosted by metavolcanic rocks skarn. sulfides, skarn, amp...
