{"title":"Noble and base metal distribution and processes affecting ore tenors in the disrupted lower stratigraphy of the Stillwater Complex, USA","authors":"Allen K. Andersen, M. Christopher Jenkins","doi":"10.1007/s00126-025-01413-4","DOIUrl":"https://doi.org/10.1007/s00126-025-01413-4","url":null,"abstract":"Exploration continues for contact-style Ni-Cu sulfide and chromitite-associated PGE mineralization in ultramafic rocks of the Stillwater Complex. At the Iron and Chrome Mountain areas, massive sulfides occur along the complex’s footwall contact and anomalous concentrations of PGE+Au are associated with the three lowermost chromitite seams. Southeast of Chrome Mountain, magmatic layering is highly disrupted by the presence of faults, magmatic breccias, serpentinized discordant dunites, pyroxenite pegmatoids, and disaggregated chromitite seams. The bulk rock chemistry, sulfide chemistry, and noble metal mineralogy of samples from this area were examined to determine the deportment of PGE and processes that led to enrichments in PGE, Au, Cu, Co and Ni. Results show that a sulfide liquid was the principal collector of PGE. If sulfide liquid was initially deposited with chromite, it was disaggregated or redistributed by subsequent melt or fluid infiltration, which may have resulted in the offset of peak PGE(+Cu, Ni) from peak Cr <jats:sub>2</jats:sub> O <jats:sub>3</jats:sub> concentrations, and upgraded PGE tenors. Upon cooling, PGE exsolved from sulfides to form discrete bismuth tellurides, arsenides, arsenic sulfides, antimonides, and alloys, commonly along the margins of sulfide globules. Calculated metal tenors are highest in the disseminated sulfides southwest of Chrome Mountain, whereas massive and net-textured sulfides near the Iron Mountain-Camp zone represent monosulfide solid solution cumulates. At progressively shallower levels, higher metal tenors combined with lower S/Se ratios are consistent with increasing R-factors from 100 to 100,000. Serpentinization and talc-tremolite alteration resulted in S loss through partial replacement of sulfides by secondary silicate+carbonate+magnetite+sulfide assemblages, further upgrading Ni-Cu-PGE tenors. The present work shows that processes responsible for the disruption of magmatic layering and post-magmatic fluid alteration along the intrusion’s lower contact led to noble and base metal enrichments.","PeriodicalId":18682,"journal":{"name":"Mineralium Deposita","volume":"29 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2025-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145711459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zinc mineralization in this area is hosted in Lower Cambrian lithologies and contains significant willemite, fraipontite, and Zn-phosphates, associated with extensive hematite- and dolomite-bearing hydrothermal alteration. Alteration mineral maps, showing relative abundance and compositional variations, were generated by applying a multiple-feature extraction methodology based on polynomial fitting and band ratios. Ground-truthing was conducted through laboratory spectroscopy and mineralogical-petrographic methods. This approach enabled the mapping of Fe oxy-hydroxides (i.e., hematite and goethite), carbonate minerals (i.e., dolomite and calcite), and dioctahedral phyllosilicates (i.e., white micas and kaolinite). It also successfully identified and mapped the ore mineral fraipontite based on its absorption feature at ~ 2260 nm. Multivariate statistical analysis and machine learning of the EnMAP imagery highlighted the co-occurrence of hematite, dolomite, and fraipontite in mineralized zones, making this assemblage a potential indicator for regional exploration of similar deposits. The study also revealed the controlling effects of fault structures on mineralization and the associated alteration haloes, with mineralized zones confined to fault-bounded rock volumes, predominantly located at intersections between interacting faults or in the proximity of lateral fault terminations. Overall, this work provides new insights into the spectral behavior of Zn-bearing minerals and demonstrates the effectiveness of hyperspectral sensing for characterizing oxidized Zn mineralization during regional prospecting programs.","PeriodicalId":18682,"journal":{"name":"Mineralium Deposita","volume":"145 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145610879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
