Mihara summit peak of the Izu-Oshima volcano in order to assess the formation process of these gases. The CO<jats:sub>2</jats:sub>/H<jats:sub>2</jats:sub>O ratio of these gases varied greatly, with the σD and σ<jats:sup>18</jats:sup>O of the H<jats:sub>2</jats:sub>O being as low as a vapor phase equilibrated with the local meteoric water. These features are explained by a mixing of the vapor equilibrated with local meteoric groundwater and primary steam, which is a vapor phase generated by the mixing of magmatic gas and a cold meteoric groundwater. We concluded that there was no direct mixing between the magmatic vapor and a vapor phase of meteoric origin in the processes involved in fumarolic gas formation.</jats:p>","journal":"Earth, Planets and Space","year":2007,"id":28172,"datarank":0.527442210771217,"base_score":2.302585092994046,"endowment":2.302585092994046,"self_citation_contribution":0.3453877639491069,"citation_network_contribution":0.1820544468221101,"self_endowment_contribution":0.3453877639491069,"citer_contribution":0.1820544468221101,"corpus_percentile":null,"corpus_rank":null,"citation_count":9,"citer_count":5,"citers_with_citation_signal":4,"citers_with_endowment":4,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":158501,"name":"Takeshi Ohba","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":2.302585092994046,"endowment":2.302585092994046,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"24523987","pmcid":null,"openalex_id":"https://openalex.org/W1970728447","authors":[],"funders":[],"total_grants":0,"fwci":0.5578,"citation_percentile":0.68680651,"influential_citations":0,"citation_trend":[{"year":2013,"count":1},{"year":2019,"count":1},{"year":2022,"count":1},{"year":2024,"count":2}],"oa_status":"hybrid","license":"cc-by","oa_locations":[{"url":"https://earth-planets-space.springeropen.com/counter/pdf/10.1186/BF03352055","host_type":"journal"},{"url":"https://earth-planets-space.springeropen.com/counter/pdf/10.1186/BF03352055","host_type":"HYBRID"},{"url":"https://earth-planets-space.springeropen.com/counter/pdf/10.1186/BF03352055","host_type":"publisher"},{"url":"https://link.springer.com/content/pdf/10.1186/BF03352055.pdf","host_type":"publisher"},{"url":"https://link.springer.com/article/10.1186/BF03352055/fulltext.html","host_type":"publisher"},{"url":"http://link.springer.com/content/pdf/10.1186/BF03352055","host_type":"publisher"},{"url":"https://doi.org/10.1186/bf03352055","host_type":"journal"}],"fields_of_study":["Methane Hydrates and Related Phenomena","Geology and Paleoclimatology Research","Geological and Geochemical Analysis","Geology","Environmental Science"],"mesh_terms":[],"keywords":["Fumarole","Meteoric water","Volcano","Geology","Water vapor","Mixing (physics)","Groundwater","Geochemistry","Mineralogy","Earth science","Chemistry"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-08T20:46:14.932972Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
