A primary challenge has been the lack of robust, data-driven metallogenic models to guide the search for deeper, concealed orebodies. This study addresses this critical knowledge gap by conducting a comprehensive geochemical investigation of the Lannigou deposit, the largest fault-controlled Carlin-type gold deposit in the basin. In this work, we integrated large, spatially matched geochemical datasets from deep drill-core rock (n = 449) and surface soil (n = 2,280) samples. Through comprehensive statistical analyses, mass transfer calculations, and innovative three-dimensional spatial visualization, we successfully (1) identified distinct ore-related (Au-As-Hg-Sb-Ag-Tl-W-Mo) and diagenetic (Bi, Co, Cu, Ni, Zn, Pb) elemental suites, delineating their controlling geological mechanisms; (2) established a robust vertical geochemical zonation pattern (Mo → Tl → Sb → W → As → Au → Ag → Hg), which serves as a powerful vector for assessing the erosional level of mineralizing systems; and (3) revealed the critical role of a deep-seated, bedding-parallel detachment fault (F1) as a master conduit, channeling ore-forming fluids from basement structures into shallower, ore-hosting reverse faults. Based on these findings, we propose a new metallogenic model wherein ore-forming fluids ascended from depth, migrated laterally along this major detachment fault, and subsequently precipitated gold within structurally favorable traps, such as secondary reverse faults on anticlinal limbs. Our metallogenic model and the identified geochemical vectors offer robust and actionable criteria for targeting concealed Carlin-type orebodies in the Youjiang Basin and analogous terranes worldwide.","PeriodicalId":18682,"journal":{"name":"Mineralium Deposita","volume":"16 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148298830","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}

Key sulphide weathering products, i.e. Fe-oxyhydroxide and atacamite, can provide insight into metal mobilisation during and after oxidation of sulphides. Ten Fe-oxyhydroxide and three massive sulphide samples from the Semenov hydrothermal cluster (13°30′N, Mid-Atlantic Ridge) were studied; five Fe-oxyhydroxides and all sulphides were analysed by LA-ICP-MS with one sulphide sample analysed by LA-TOF-ICP-MS mapping. Additionally, a sequential leaching study comprising nine Fe-oxyhydroxide samples was performed. Copper is mainly sequestered into the sulphide weathering products atacamite (~ 60%) and Fe-oxyhydroxide (~ 30%). Initially, Fe‑oxyhydroxide precipitates as ferrihydrite, inheriting the metal content of its sulphide precursor (e.g., pyrite or chalcopyrite). Concurrently, Au and Ag are displaced from the sulphide and become concentrated along the oxidation front at the sulphide rims rather than being incorporated into the nascent Fe‑oxyhydroxide. As oxidation proceeds, further breakdown of sulphides such as chalcopyrite, releases Cu that initially adsorb onto existing Fe‑oxyhydroxide. When sufficient mobilised Cu reacts with oxygenated seawater, atacamite precipitates, sequestering the Cu in a stable mineral form, serving as an exploration indicator for Cu‑rich Fe‑oxyhydroxide deposits and underlying massive sulphide deposits. Complete sulphide oxidation leads to the loss of Au and Ag from the solid system into seawater or their migration downwards toward a redox boundary within the SMS mound. Crystallisation of ferrihydrite into more stable goethite liberates substantial amounts of Cu (92%) and Zn (57%). However, the metal loss caused by this process may be limited if released metals re-adsorbed onto adjacent Fe‑oxyhydroxide. These results reveal that Fe‑oxyhydroxides can act as effective long‑term traps for Cu and Zn, suggesting that older, fully or partially oxidised off-axis SMS deposits may retain considerable base metals, expanding exploration areas.","PeriodicalId":18682,"journal":{"name":"Mineralium Deposita","volume":"33 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148298831","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}
