{"id":"https://openalex.org/T11740","display_name":"Geochemistry and Elemental Analysis","description":"This cluster of papers focuses on the geochemistry, formation mechanisms, environmental impacts, and biological interactions of manganese oxides in sedimentary environments. It explores the relationships between manganese oxides, rare earth elements, trace element composition of sedimentary rocks, provenance analysis, and weathering processes. The cluster also investigates the potential of deep-ocean mineral deposits as a source of critical metals for high- and green-technology applications.","keywords":[{"id":"https://openalex.org/keywords/sediment-geochemistry","display_name":"sediment geochemistry","score":0.2676},{"id":"https://openalex.org/keywords/ore","display_name":"ore rock","score":0.2942},{"id":"https://openalex.org/keywords/manganese-nodules","display_name":"manganese nodules","score":0.6188},{"id":"https://openalex.org/keywords/chemical-weathering","display_name":"chemical weathering","score":0.2046},{"id":"https://openalex.org/keywords/heavy-minerals","display_name":"heavy minerals","score":0.3454},{"id":"https://openalex.org/keywords/chert","display_name":"chert","score":0.234},{"id":"https://openalex.org/keywords/manganese-ore","display_name":"manganese ore","score":0.413},{"id":"https://openalex.org/keywords/manganese-deposits","display_name":"manganese deposits","score":0.5584},{"id":"https://openalex.org/keywords/hydrothermal-ore-deposits","display_name":"hydrothermal deposits","score":0.3187},{"id":"https://openalex.org/keywords/ferromanganese-crusts","display_name":"ferromanganese crusts","score":0.7718},{"id":"https://openalex.org/keywords/europium-anomaly","display_name":"Eu anomaly","score":0.2729},{"id":"https://openalex.org/keywords/chemical-index-of-alteration","display_name":"chemical index of alteration","score":0.4535},{"id":"https://openalex.org/keywords/major-element-geochemistry","display_name":"major element geochemistry","score":0.2748},{"id":"https://openalex.org/keywords/sedimentary-mineralogy","display_name":"sediment mineralogy","score":0.2127},{"id":"https://openalex.org/keywords/minor-elements","display_name":"minor elements","score":0.2549},{"id":"https://openalex.org/keywords/manganese-crusts","display_name":"manganese crusts","score":0.8693},{"id":"https://openalex.org/keywords/ferromanganese-nodules","display_name":"ferromanganese nodules","score":0.7392},{"id":"https://openalex.org/keywords/birnessite","display_name":"birnessite","score":0.2584},{"id":"https://openalex.org/keywords/hydrothermal-plumes","display_name":"hydrothermal plumes","score":0.3557},{"id":"https://openalex.org/keywords/iron-formation","display_name":"iron-formation","score":0.2268},{"id":"https://openalex.org/keywords/marine-sediment-geochemistry","display_name":"marine sediment geochemistry","score":0.3892},{"id":"https://openalex.org/keywords/ree-fractionation","display_name":"REE fractionation","score":0.431},{"id":"https://openalex.org/keywords/hydrothermal-venting","display_name":"hydrothermal venting","score":0.2746},{"id":"https://openalex.org/keywords/marine-geochemistry","display_name":"marine geochemistry","score":0.3488},{"id":"https://openalex.org/keywords/seafloor-mineral-deposits","display_name":"seafloor mineral deposits","score":0.7963}],"legacy_keywords":"Manganese Oxides; Rare Earth Elements; Sedimentary Rocks; Geochemistry; Provenance Analysis; Trace Element Composition; Environmental Impacts; Deep-Ocean Mineral Deposits; Bacterial Oxidation; Weathering","ids":{"openalex":"https://openalex.org/T11740","wikipedia":"https://en.wikipedia.org/wiki/Manganese_oxide_minerals"},"subfield":{"id":"https://openalex.org/subfields/1906","display_name":"Geochemistry and Petrology"},"field":{"id":"https://openalex.org/fields/19","display_name":"Earth and Planetary Sciences"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"},"siblings":[{"id":"https://openalex.org/T10398","display_name":"Groundwater and Isotope Geochemistry"},{"id":"https://openalex.org/T12218","display_name":"Coal and Its By-products"},{"id":"https://openalex.org/T13067","display_name":"Geological Modeling and Analysis"},{"id":"https://openalex.org/T13209","display_name":"Cold Fusion and Nuclear Reactions"},{"id":"https://openalex.org/T13443","display_name":"Mineralogy and Gemology Studies"}],"works_count":132023,"cited_by_count":1364884,"works_api_url":"https://api.openalex.org/works?filter=topics.id:T11740","updated_date":"2026-10-22T03:01:35","created_date":"2024-01-23T15:27:11"}
