RESOURCE ESTIMATES ARE ALREADY AVAILABLE FOR SOME OF THE LARGEST SMS DEPOSITS ON SLOW-SPREADING RIDGES BUT NOT ON ULTRASLOW-SPREADING RIDGES. BASED ON GEOLOGICAL MAPPING AND SAMPLING, THIS STUDY INVESTIGATES THE DISTRIBUTION AND CONTENT OF SULFIDE-RICH DEPOSITS IN THE YUHUANG-1 HYDROTHERMAL FIELD (YHF), LOCATED ON THE ULTRASLOW-SPREADING SOUTHWEST INDIAN RIDGE. THE SULFIDE-RICH DEPOSITS IN THE YHF ARE COMPOSED OF TWO AREAS \u223c500 M APART: THE SOUTHWEST SULFIDE AREA (SWS) AND THE NORTHEAST SULFIDE AREA (NES). WE CALCULATED THE VOLUME OF SULFIDE-RICH MOUNDS IN THE YHF AND ARRIVED AT A TOTAL ACCUMULATION OF \u223c10.6 \u00d7 106 TONS, INCLUDING AT LEAST \u223c7.5 \u00d7 105 TONS OF COPPER AND ZINC AND \u223c18 TONS OF GOLD. FURTHERMORE, CONSIDERING THE COVERAGE OF LAYERED HYDROTHERMAL SEDIMENT MIXED WITH SULFIDE-RICH BRECCIAS, WHICH MAY HAVE UNDERLYING MASSIVE SULFIDE DEPOSITS, THE MAXIMUM TOTAL MASS WAS ESTIMATED AT \u223c45.1 \u00d7 106 TONS. THIS SUGGESTS THAT THE YHF IS ONE OF THE LARGEST SMS DEPOSITS WORLDWIDE AND CONFIRM THAT ULTRASLOW-SPREADING RIDGES HAVE THE GREATEST POTENTIAL TO FORM LARGE-SCALE SMS DEPOSITS.<\/p>","protected":false},"author":2,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","format":"standard","class_list":["post-434369","tnc_col_19837_item","type-tnc_col_19837_item","status-publish","format-standard","hentry","tnc_tax_19993-sdg-14-life-below-water","tnc_tax_19818-english","tnc_tax_19716-institute-of-science-and-environment","tnc_tax_19659-journal-article"],"taxonomy_info":[],"featured_image_src_large":false,"author_info":[],"comment_info":0,"featured_img":false,"coauthors":[],"author_meta":{"author_link":"https:\/\/library.usj.edu.mo\/zh\/author\/emilychan\/","display_name":"emily chan"},"relative_dates":{"created":"Posted 2 \u5929 ago","modified":"Updated 2 \u5929 ago"},"absolute_dates":{"created":"Posted on 24 8 \u6708, 2026","modified":"Updated on 24 8 \u6708, 2026"},"absolute_dates_time":{"created":"Posted on 24 8 \u6708, 2026 5:24 \u4e0b\u5348","modified":"Updated on 24 8 \u6708, 2026 6:32 \u4e0b\u5348"},"featured_img_caption":"","tax_additional":{"tnc_tax_19993":{"linked":["<a href=\"https:\/\/library.usj.edu.mo\/zh\/sdgs\/sdg-14-life-below-water\/\" class=\"advgb-post-tax-term\">SDG 14 Life Below Water<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">SDG 14 Life Below Water<\/span>"],"slug":"tnc_tax_19993","name":"SDGs"},"tnc_tax_19818":{"linked":["<a href=\"https:\/\/library.usj.edu.mo\/zh\/language\/english\/\" class=\"advgb-post-tax-term\">ENGLISH<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">ENGLISH<\/span>"],"slug":"tnc_tax_19818","name":"LANGUAGE"},"tnc_tax_19716":{"linked":["<a href=\"https:\/\/library.usj.edu.mo\/zh\/faculty-research-unit\/institute-of-science-and-environment\/\" class=\"advgb-post-tax-term\">INSTITUTE OF SCIENCE AND ENVIRONMENT<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">INSTITUTE OF SCIENCE AND ENVIRONMENT<\/span>"],"slug":"tnc_tax_19716","name":"FACULTY \/ RESEARCH UNIT"},"tnc_tax_19664":{"linked":[],"unlinked":[],"slug":"tnc_tax_19664","name":"SUBJECT"},"tnc_tax_19659":{"linked":["<a href=\"https:\/\/library.usj.edu.mo\/zh\/resource-type\/journal-article\/\" class=\"advgb-post-tax-term\">Journal Article<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">Journal Article<\/span>"],"slug":"tnc_tax_19659","name":"Document Type"}},"series_order":"","_links":{"self":[{"href":"https:\/\/library.usj.edu.mo\/zh\/wp-json\/wp\/v2\/tnc_col_19837_item\/434369","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/library.usj.edu.mo\/zh\/wp-json\/wp\/v2\/tnc_col_19837_item"}],"about":[{"href":"https:\/\/library.usj.edu.mo\/zh\/wp-json\/wp\/v2\/types\/tnc_col_19837_item"}],"replies":[{"embeddable":true,"href":"https:\/\/library.usj.edu.mo\/zh\/wp-json\/wp\/v2\/comments?post=434369"}],"version-history":[{"count":1,"href":"https:\/\/library.usj.edu.mo\/zh\/wp-json\/wp\/v2\/tnc_col_19837_item\/434369\/revisions"}],"predecessor-version":[{"id":435723,"href":"https:\/\/library.usj.edu.mo\/zh\/wp-json\/wp\/v2\/tnc_col_19837_item\/434369\/revisions\/435723"}],"wp:attachment":[{"href":"https:\/\/library.usj.edu.mo\/zh\/wp-json\/wp\/v2\/media?parent=434369"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
