{"cited_by_count":2320541,"description":"This cluster of papers focuses on the geological and plate tectonic evolution of the South China Sea, including topics such as Cenozoic rifting, crustal structure, seafloor spreading, and sedimentary evolution. It explores the tectonic models, volcanic activity, and the development of marginal basins in the region.","display_name":"Geological and Geophysical Studies","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T13177","wikipedia":"https://en.wikipedia.org/wiki/South_China_Sea"},"field_id":"19","id":"T13177","keywords":[{"display_name":"volcanic activity","id":"volcanism","score":0.3073,"url":"https://openalex.org/keywords/volcanism"},{"display_name":"crustal structure","id":"crustal-structure","score":0.2411,"url":"https://openalex.org/keywords/crustal-structure"},{"display_name":"oceanic crust","id":"oceanic-crust","score":0.3356,"url":"https://openalex.org/keywords/oceanic-crust"},{"display_name":"plate tectonics","id":"plate-tectonics","score":0.3248,"url":"https://openalex.org/keywords/plate-tectonics"},{"display_name":"continental rifting","id":"continental-rifting","score":0.5046,"url":"https://openalex.org/keywords/continental-rifting"},{"display_name":"rock dredge sample","id":"rock-dredge-sample","score":0.3792,"url":"https://openalex.org/keywords/rock-dredge-sample"},{"display_name":"crustal thickness","id":"crustal-thickness","score":0.3289,"url":"https://openalex.org/keywords/crustal-thickness"},{"display_name":"volcano monitoring","id":"volcano-monitoring","score":0.2357,"url":"https://openalex.org/keywords/volcano-monitoring"},{"display_name":"rifting","id":"rifting","score":0.4501,"url":"https://openalex.org/keywords/rifting"},{"display_name":"passive continental margin","id":"passive-margin","score":0.3826,"url":"https://openalex.org/keywords/passive-margin"},{"display_name":"volcanoes","id":"volcanoes","score":0.2008,"url":"https://openalex.org/keywords/volcanoes"},{"display_name":"seafloor spreading","id":"seafloor-spreading","score":0.612,"url":"https://openalex.org/keywords/seafloor-spreading"},{"display_name":"rift basins","id":"rift-basins","score":0.3886,"url":"https://openalex.org/keywords/rift-basins"},{"display_name":"marine geology","id":"marine-geology","score":0.2347,"url":"https://openalex.org/keywords/marine-geology"},{"display_name":"extensional tectonics","id":"extensional-tectonics","score":0.2548,"url":"https://openalex.org/keywords/extensional-tectonics"},{"display_name":"mid-ocean ridge","id":"mid-ocean-ridge","score":0.43,"url":"https://openalex.org/keywords/mid-ocean-ridge"},{"display_name":"continental margin","id":"continental-margin","score":0.2273,"url":"https://openalex.org/keywords/continental-margin"},{"display_name":"continental drift","id":"continental-drift","score":0.3027,"url":"https://openalex.org/keywords/continental-drift"},{"display_name":"volcanic landforms","id":"volcanic-landforms","score":0.2583,"url":"https://openalex.org/keywords/volcanic-landforms"},{"display_name":"Mid-Atlantic Ridge","id":"mid-atlantic-ridge","score":0.2396,"url":"https://openalex.org/keywords/mid-atlantic-ridge"},{"display_name":"Moho depth","id":"moho-depth","score":0.3756,"url":"https://openalex.org/keywords/moho-depth"},{"display_name":"crustal thinning","id":"crustal-thinning","score":0.4669,"url":"https://openalex.org/keywords/crustal-thinning"},{"display_name":"continental breakup","id":"continental-breakup","score":0.5866,"url":"https://openalex.org/keywords/continental-breakup"},{"display_name":"crustal extension","id":"crustal-extension","score":0.3359,"url":"https://openalex.org/keywords/crustal-extension"},{"display_name":"submarine volcanism","id":"submarine-volcanism","score":0.371,"url":"https://openalex.org/keywords/submarine-volcanism"}],"legacy_keywords":["Plate Tectonics","Cenozoic Evolution","Rifting","Crustal Structure","Tectonic Model","Seafloor Spreading","Marginal Basin","Volcanism","Sedimentary Evolution","Continental Margin"],"openalex_id":"https://openalex.org/T13177","source_created_date":"2024-01-23T15:27:17","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1907","url":"/topics/T13177","works_api_url":"https://api.openalex.org/works?filter=topics.id:T13177","works_count":209308,"label":"Geological and Geophysical Studies","provider":"openalex","revision":"05760ab16ad2f324","taxonomy_revision":"f050b5d4780b1289","title":"Geological and Geophysical Studies","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"38285871267348607","address_version":"morton4x16-v1","coordinates":[3,19,1907,13177],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
