In some instances, however, younger volcanic structures and vents may overlap with older edifices. The genetic links between such co-located eruptions remain unclear. We mapped and analysed the stratigraphic relationships between eruptive units on the 400 × 900-m island of Chagwido off the western coast of Jeju Island, a Pleistocene to Holocene intraplate volcanic field. Chagwido consists of an eastern, older tuff ring with a nested scoria cone and a western tuff, scoria and lava flow sequence. The two stratigraphic packages are separated by a prominent paleosol. The East-Chagwido tuff and scoria deposits were eroded and a period of intense weathering and soil development occurred, before a subsequent West-Chagwido tuff ring and scoria cone and lava complex was erupted. The two eruptions were fed by three chemically distinct magmas. The older eastern eruption consists of magma with composition transitional between high-Al alkalic basalt and low-Al alkalic basalt and has stratigraphic characteristics, composition and syn-eruptive trends akin to the neighbouring Dangsanbong tuff cone. This magma type is typical for the transitional stage from high-Al alkalic (pre 500 ka) to low-Al alkalic (post 250 ka) identified for the greater Jeju volcanic system. The East-Chagwido volcanic complex thus formed as the westernmost in a chain of three volcanoes along a fissure system, with a small volcanic remnant island Wado 1 km to the east and the large Dangsanbong tuff cone another 1 km eastward. A new Ar/Ar age of 446 ± 22 ka for Dangsanbong likely characterizes the age of the whole chain. The second, West-Chagwido eruption started with low-Al alkalic basalt forming a phreatomagmatic phase and ended with subalkalic basalt forming a scoria cone and lava flows. The occurrence of subalkalic lavas is known across Jeju to have started only at 250 ka, and thus, the well-developed paleosol represents at least 200 kyr between the two co-located eruptions. The distinctive magma compositions show that each eruption tapped an independent region within the same underlying mantle source. These observations show that contrary to most assumptions of monogenetic volcanism, an already “tapped” source region may become fertile again through mantle convection/migration and eruptions can thus be expected from old vent sites in long-lived volcanic fields.}, year = {2015}, eissn = {1432-0819}, orcid-numbers = {Brenna, Marco/0000-0001-6096-6999} } @article{MTMT:25663921, title = {Monogenetic volcanism: personal views and discussion}, url = {https://m2.mtmt.hu/api/publication/25663921}, author = {Németh, Károly and Kereszturi, G}, doi = {10.1007/s00531-015-1243-6}, journal-iso = {INT J EARTH SCI}, journal = {INTERNATIONAL JOURNAL OF EARTH SCIENCES}, volume = {104}, unique-id = {25663921}, issn = {1437-3254}, year = {2015}, eissn = {1437-3262}, pages = {2131-2146} } @article{MTMT:25688524, title = {Towards the reconstruction of the shallow plumbing system of the Barombi Mbo Maar (Cameroon) Implications for diatreme growth processes of a polygenetic maar volcano}, url = {https://m2.mtmt.hu/api/publication/25688524}, author = {Tchamabe, Boris Chako and Ohba, Takeshi and Kereszturi, Gabor and Németh, Károly and Aka, Festus Tongwa and Youmen, Dieudonne and Issa, . and Miyabuchi, Yasuo and Ooki, Seigo and Tanyileke, Gregory and Hell, Joseph Victor}, doi = {10.1016/j.jvolgeores.2015.06.004}, journal-iso = {J VOLCANOL GEOTH RES}, journal = {JOURNAL OF VOLCANOLOGY AND GEOTHERMAL RESEARCH}, volume = {301}, unique-id = {25688524}, issn = {0377-0273}, year = {2015}, eissn = {1872-6097}, pages = {293-313} } @article{MTMT:2112719, title = {Syn-eruptive morphometric variability of monogenetic scoria cones on Tenerife (Canary Islands)}, url = {https://m2.mtmt.hu/api/publication/2112719}, author = {Kereszturi, G and Jordán, Győző and Németh, Károly and Dóniz-Páez, J F}, doi = {10.1007/s00445-012-0658-1}, journal-iso = {B VOLCANOL}, journal = {BULLETIN OF VOLCANOLOGY}, volume = {74}, unique-id = {2112719}, issn = {0258-8900}, year = {2012}, eissn = {1432-0819}, pages = {2171-2185} } @{MTMT:31985553, title = {Monogenetic Basaltic Volcanoes: Genetic Classification, Growth, Geomorphology and Degradation}, url = {https://m2.mtmt.hu/api/publication/31985553}, author = {Kereszturi, Gabor and Németh, Károly}, booktitle = {Updates in Volcanology : New Advances in Understanding Volcanic Systems}, doi = {10.5772/51387}, unique-id = {31985553}, year = {2012}, pages = {3-89} } @article{MTMT:1506100, title = {Maars and scoria cones: The enigma of monogenetic volcanic fields}, url = {https://m2.mtmt.hu/api/publication/1506100}, author = {Németh, Károly and Haller, M J and Siebe, C}, doi = {10.1016/j.jvolgeores.2011.03.001}, journal-iso = {J VOLCANOL GEOTH RES}, journal = {JOURNAL OF VOLCANOLOGY AND GEOTHERMAL RESEARCH}, volume = {201}, unique-id = {1506100}, issn = {0377-0273}, year = {2011}, eissn = {1872-6097}, pages = {v-viii} } @article{MTMT:1384578, title = {Volcanic architecture, eruption mechanism and landform evolution of a Plio/Pleistocene intracontinental basaltic polycyclic monogenetic volcano from the Bakony-Balaton Highland Volcanic Field, Hungary}, url = {https://m2.mtmt.hu/api/publication/1384578}, author = {Kereszturi, G and Csillag, Gábor and Németh, Károly and Sebe, Krisztina and Balogh, Kadosa and Jáger, Viktor}, doi = {10.2478/v10085-010-0019-2}, journal-iso = {CENT EUR J GEOSCI}, journal = {CENTRAL EUROPEAN JOURNAL OF GEOSCIENCES}, volume = {2}, unique-id = {1384578}, issn = {2081-9900}, abstract = {Bondoró Volcanic Complex (shortly Bondoró) is one of the most complex eruption centre of Bakony-Balaton Highland Volcanic Field, which made up from basaltic pyroclastics sequences, a capping confined lava field (~4 km 2) and an additional scoria cone. Here we document and describe the main evolutional phases of the Bondoró on the basis of facies analysis, drill core descriptions and geomorphic studies and provide a general model for this complex monogenetic volcano. Based on the distinguished 13 individual volcanic facies, we infer that the eruption history of Bondoró contained several stages including initial phreatomagmatic eruptions, Strombolian-type scoria cones forming as well as effusive phases. The existing and newly obtained K-Ar radiometric data have confirmed that the entire formation of the Bondoró volcano finished at about 2.3 Ma ago, and the time of its onset cannot be older than 3.8 Ma. Still K-Ar ages on neighbouring formations (e.g. Kab-hegy, Agár-teto) do not exclude a long-lasting eruptive period with multiple eruptions and potential rejuvenation of volcanic activity in the same place indicating stable melt production beneath this location. The prolonged volcanic activity and the complex volcanic facies architecture of Bondoró suggest that this volcano is a polycyclic volcano, composed of at least two monogenetic volcanoes formed more or less in the same place, each erupted through distinct, but short lived eruption episodes. The total estimated eruption volume, the volcanic facies characteristics and geomorphology also suggests that Bondoró is rather a small-volume polycyclic basaltic volcano than a polygenetic one and can be interpreted as a nested monogenetic volcanic complex with multiple eruption episodes. It seems that Bondoró is rather a "rule" than an "exception" in regard of its polycyclic nature not only among the volcanoes of the Bakony-Balaton Highland Volcanic Field but also in the Neogene basaltic volcanoes of the Pannonian Basin.}, keywords = {SCORIA CONE; MAAR; polygenetic; polycyclic; monogenetic}, year = {2010}, eissn = {1896-1517}, pages = {362-384}, orcid-numbers = {Sebe, Krisztina/0000-0002-4647-2199; Jáger, Viktor/0000-0003-1283-5198} }
