Alteration of the host rocks occurred in two stages. The earlier regional alteration stage is characterized by the presence of 2M- and IM-type muscovite, albite, chlorite, calcite and epidote, whereas muscovite and Fe-chlorite formation at the expense of partly albitized plagioclase and altered biotite or hornblende occurred in the following hydrothermal stage. Pyrite, sphalerite, galena and siderite are present in the central part of the hydrothermal alteration zone. Oxygen and hydrogen isotopic ratios of secondary muscovite show that regional alteration proceeded under the meteoric circulation, and that the hydrothermal fluid for the second stage had chemical and stable isotopic characteristics of non-meteoric origin similar to the present-day Arima brine. The oxygen and to a lesser extent the hydrogen isotopic ratios of the muscovite rapidly decrease with increasing distance from the central zone of hydrothermal alteration. The isotopic variation is best interpreted as reflecting rapidly decreasing fluid/rock ratios with increasing distance of fluid penetration from the narrow hydrothermal alteration zone into the surrounding area.  Speciation computation for the present-day brines at Arima Spa indicates that they are saturated with siderite but not with calcite at depth, in good accord with the mineralogical observations. Upon ascent the brines are diluted by HCO3-rich shallow ground water and are saturated with respect to both siderite and calcite. The present-day Arima hydrothermal system is a remnant of the second stage hydrothermal activity."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388846274211968","@type":"Researcher","foaf:name":[{"@value":"Harue Masuda"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388846274211970","@type":"Researcher","foaf:name":[{"@value":"Hitoshi Sakai"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388846274211969","@type":"Researcher","foaf:name":[{"@value":"Hitoshi Chiba"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388846274211971","@type":"Researcher","foaf:name":[{"@value":"Yukihiro Matsuhisa"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388846274211972","@type":"Researcher","foaf:name":[{"@value":"Takeshi Nakamura"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00167037"}],"prism:publicationName":[{"@value":"Geochimica et Cosmochimica Acta"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"1986-01","prism:volume":"50","prism:number":"1","prism:startingPage":"19","prism:endingPage":"28"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:001670378690044X?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:001670378690044X?httpAccept=text/plain"}],"createdAt":"2003-08-06","modifiedAt":"2019-03-16","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360283690913949056","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Widespread distribution of ascending fluids transporting mantle helium in the fore-arc region and their upwelling processes: Noble gas and major element composition of deep groundwater in the Kii Peninsula, southwest Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1360580230597926272","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Three-dimensional structure and sources of groundwater masses beneath the Osaka Plain, Southwest Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1360580232184726144","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Strontium Isotope Characteristics (δ<sup>88/86</sup>Sr, <sup>87</sup>Sr/<sup>86</sup>Sr) of Arima‐Type Brines Originated From Slab‐Fluids"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679528304128","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Relationship between geological structure and helium isotopes in deep ground-water from the Osaka Basin: Application to deep groundwater hydrology"},{"@value":"Relationship between geological structure and helium isotope in deep groundwater from the Osaka Basin: application to deep groundwater hydrology"}]},{"@id":"https://cir.nii.ac.jp/crid/1390294740098255104","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"From Hot Springs to Deep-seated Fluids: History of Hot Spring Studies from the Viewpoints of Energy and Material Circulations in the Solid Earth"},{"@language":"ja","@value":"温泉から深部流体へ"}]},{"@id":"https://cir.nii.ac.jp/crid/1390861305854382336","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Learning Society via groundwater research works"},{"@language":"ja","@value":"地下水研究から社会を学ぶ"}]},{"@id":"https://cir.nii.ac.jp/crid/2051714792046916224","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Electrical conductivity of brine-bearing quartzite at 1 GPa : implications for fluid content and salinity of the crust"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/0016-7037(86)90044-x"},{"@type":"OPENAIRE","@value":"doi_dedup___::f6fdf0088cff752f775084499a58cdad"},{"@type":"CROSSREF","@value":"10.1186/1880-5981-66-2_references_DOI_UfyYu3wwcHswmsWJWwoNMdbEiYI"},{"@type":"CROSSREF","@value":"10.2343/geochemj.42.61_references_DOI_UfyYu3wwcHswmsWJWwoNMdbEiYI"},{"@type":"CROSSREF","@value":"10.5917/jagh.65.267_references_DOI_UfyYu3wwcHswmsWJWwoNMdbEiYI"},{"@type":"CROSSREF","@value":"10.1016/j.gca.2016.03.017_references_DOI_UfyYu3wwcHswmsWJWwoNMdbEiYI"},{"@type":"CROSSREF","@value":"10.5026/jgeography.131.573_references_DOI_UfyYu3wwcHswmsWJWwoNMdbEiYI"},{"@type":"CROSSREF","@value":"10.1016/j.ejrh.2022.101193_references_DOI_UfyYu3wwcHswmsWJWwoNMdbEiYI"},{"@type":"CROSSREF","@value":"10.1029/2022gl100309_references_DOI_4UfOnBO8kqaMiWozlpVTIDUjjbE"}]}
