Based on combined zircon U-Th and (U-Th)/He geochronology, Ciomadul volcanism is divided into two main eruptive periods: Old Ciomadul (1Ma – 300 ka; OCEP) and Young Ciomadul Eruptive Period (160–30ka; YCEP). OCEP activity comprises Eruptive Epochs 1–3, whereas new ages for eight lava domes and four pyroclastic units belonging to the YCEP lead to its further subdivision into two eruptive epochs: Eruptive Epochs 4 and 5. The extrusion of most of the lava domes occurred between 160 and 90 ka (Eruptive Epoch 4) during three eruptive episodes at ca. 155ka, 135 ka and 95 ka (Eruptive Episodes 4/1, 4/ 2 and 4/3, respectively) along a NE-SW lineament, which is perpendicular to the regional NW-SE trend of the Călimani-Gurghiu-Harghita volcanic chain. Eruptive Epoch 5 occurred after a ca. 40 kyr of quiescence at ca. 55–30 ka, and is mainly characterized by explosive eruptions with a minor lava dome building activity. All of the dated pyroclastic outcrops, together with the lava dome of Piscul Pietros, belong to the older Eruptive Episode 5/1, with an eruption age of 55–45ka. The eruption centers of Eruptive Epoch 5 are located at the junction of the conjugated NW-SE and NE-SW lineaments defined by the older eruptive centers. The whole-rock geochemistry of all studied samples is fairly homogeneous (SiO2=63–69wt%, K2O=3–4wt%). It also overlaps with the composition of the lava domes of the Old Ciomadul Eruptive Period, implying a monotonous geochemical characteristic for the past 1 Myr. The eruption rates for the Ciomadul volcanism were determined based on the erupted lava dome volume calculations, supplemented with the eruption ages. The activity peaked during the Eruptive Epoch 4 (160–90 ka), having an eruption rate of 0.1 km3 /kyr. In comparison, these values are 0.05km3 /kyr for the YCEP (160–30ka) and 0.01 km3 /kyr for the overall Ciomadul volcanism (1Ma–30 ka). Based on the geochemical characteristics, the quiescence periods and the lifetime of the complex, as well as the relatively small amount of erupted material, this volcanic system can be placed in a subduction-related post-collisional geodynamic setting, which shows strong chemical similarities to continental arc volcanism. The commonly found long repose times between the active phases suggest that the nature of a volcano cannot be understood solely based on the elapsed time since the last eruption. Instead, comprehensive geochronology, coupled with the understanding of the magma storage behavior could be a base of hazard assessment for volcanic fields, where the last eruptions occurred several 10's of thousand years ago and therefore they are not considered as potentially active. true 2019 true true true false true false GREEN 2026-05-27 true http://real.mtak.hu/91737 48 0 47 18 28 40 41 35 40 40 40 17 17 18 30 0 48 18 47 18 0 21 21 Folyóiratcikk Journal Article 24 39 Könyvrészlet Chapter in Book 25 3 Könyv Book 23 0 Egyéb konferenciaközlemény Conference paper 31 5 Egyéb konferenciakötet Conference proceedings 32 0 Oltalmi formák Protection forms 26 0 Disszertáció Thesis 28 1 Egyéb Miscellaneous 29 0 Alkotás Achievement 22 0 Kutatási adat Research data 33 0 Folyóiratcikk Journal Article 24 0 0 0 Könyvrészlet Chapter in Book 25 0 0 0 Könyv Book 23 0 0 0 Egyéb konferenciaközlemény Conference paper 31 0 0 0 Egyéb konferenciakötet Conference proceedings 32 0 0 0 Oltalmi formák Protection forms 26 0 0 0 Disszertáció Thesis 28 0 0 0 Egyéb Miscellaneous 29 0 0 0 Alkotás Achievement 22 0 0 0 Kutatási adat Research data 33 0 0 0 2019 0 6 0 6 0 2020 0 6 2 6 2 2021 0 12 5 12 5 2022 0 6 4 6 4 2023 0 8 3 8 3 2024 0 4 2 4 2 2025 0 5 1 5 1 2026 0 1 1 1 1 Q1 A false 10048489,10034585 false false false 2019-02-24T08:40:01.539+0000 2019-02-20T12:03:51.111+0000 Kőzettan-Geokémiai Tanszék (ELTE / TTK / Ft_K); MTA Atommagkutató Intézet; MTA-ELTE Vulkanológiai kutatócsoport (ELTE / TTK / Ft_K) 6 31 3 8 0 true 10014568 10067876 Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 85549215 /api/authorship/85549215 1 0.125 true false true Author 10048489 /api/author/10048489 Molnár Kata true 10048489 true Molnár Kata true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 85292289 /api/authorship/85292289 2 0.125 false false Author 10016373 /api/author/10016373 Haranginé Lukács Réka true 10016373 true Lukács Réka true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 85549216 /api/authorship/85549216 3 0.125 false false Author 10007580 /api/author/10007580 Dunkl István true 10007580 true Dunkl István true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 85292291 /api/authorship/85292291 4 0.125 false false Schmitt Axel K. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 85292292 /api/authorship/85292292 5 0.125 false false Author 10029901 /api/author/10029901 Kiss Balázs true 10029901 true Kiss Balázs true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 85292293 /api/authorship/85292293 6 0.125 false false Seghedi Ioan true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 85549217 /api/authorship/85549217 7 0.125 false false Author 10034585 /api/author/10034585 Szepesi János true 10034585 true Szepesi János true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 85549218 /api/authorship/85549218 8 0.125 false true Author 10008370 /api/author/10008370 Harangi Szabolcs true 10008370 true Harangi Szabolcs true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PublicationIdentifier 15189802 /api/publicationidentifier/15189802 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true IDENTICAL 10.1016/j.jvolgeores.2019.01.025 https://doi.org/10.1016/j.jvolgeores.2019.01.025 false true PublicationIdentifier 15381635 /api/publicationidentifier/15381635 SwordSource 36 /api/publicationsource/36 PublicationSourceType 10007 /api/publicationsourcetype/10007 true true true REAL REAL http://real.mtak.hu/@@@ true true 36 true GREEN true IDENTICAL 91737 http://real.mtak.hu/91737 true true PublicationIdentifier 15554715 /api/publicationidentifier/15554715 PlainSource 1 /api/publicationsource/1 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 000463305400009 https://www.webofscience.com/wos/woscc/full-record/000463305400009 true true PublicationIdentifier 15236453 /api/publicationidentifier/15236453 PlainSource 3 /api/publicationsource/3 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 85061550104 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-85061550104 false true Classification 10417 /api/classification/10417 true true MtaRating 11435122 /api/mtarating/11435122 RatingType 10031 /api/ratingtype/10031 X.
