Abstract:

AbstractBased on structural, geochemical, sedimentological and geochronological studies, we have formulated a model for the evolution of the late Archaean Abitibi greenstone belt of the Superior Province of Canada. The southern volcanic zone (SVZ) of the belt is dominated by komatiitic to tholeiitic volcanic plateaux and large, bimodal, mafic-felsic volcanic centres. These volcanic rocks were erupted between approximately 2710 Ma and 2700 Ma in a series of rift basins formed as a result of wrench-fault tectonics.The SVZ superimposes an older volcanic terrane which is characterized in the north

Abstract:

Late Apine orogenic volcanism appears immediately after the main phase of folding and thrusting in the Carpathian-Balkan area. The age of the volcainic manifestations is Priabonian-Oligocene (after Ilirian phase) in the Balkan segment and Miocene-Pliocene (after Savian phase) in the Carpathian segment, respectively. Most of the acid volcanics are formed by crustal melting, whereas a smaller part are differentiates of basaltic and intermediate magmas. The first one has higher SiO2 content than the second. K2O content increases from the North to the South: in the Carpatian segment the acid volca

AbstractTwo small monogenetic volcanoes are exposed at Mount Early and Sheridan Bluff, in the upper reaches of Scott Glacier. In addition, the presence of abundant fresh volcanic detritus in moraines at two other localities suggests further associated volcanism, now obscured by the modern Antarctic ice sheet. One of those occurrences has been attributed to a small subglacial volcano onlyc.200 km from South Pole, making it the southernmost volcano in the world. All of the volcanic outcrops in the Scott Glacier region are grouped in a newly defined Upper Scott Glacier Volcanic Field, which is pa

The Neogene volcanic products of the Burda mountain range nearby Štúrovo belong to Burda Formation.

Submarine extrusive volcanic domes of andesites are typical. In the upper part of the Burda Formation, pyroclastic and epiclastic facies of andesites were formed.

The geological study of volcanic deposits and landforms is a key step in reconstructing past volcanic eruptions and for the evaluation of volcanic hazards and associated risks.

Shallow-seated controls on the evolution of the Upper Pliocene Kopasz-hegy nested monogenetic volcanic chain in the Western Pannonian Basin (Hungary)Monogenetic, nested volcanic complexes (e.g. Tihany) are common landforms in the Bakony-Balaton Highland Volcanic Field (BBHVF, Hungary), which was active during the Late Miocene up to the Early Pleistocene. These types of monogenetic volcanoes are usually evolved in a slightly different way than their "simple" counterparts. The Kopasz-hegy Volcanic Complex (KVC) is inferred to be a vent complex, which evolved in a relatively complex way as compar

The purpose of this study is to establish relationship between a source for final eruptions on the Dzotol volcano and those for the whole preceded Late Cenozoic volcanism in the Dariganga field. Major oxides, trace elements, and Pb isotopic ratios in rocks of the volcanic field are indicative for generation of magmatic melts in a homogeneous mantle region. In final eruptions of the Dzotol volcano, rocks show, on the one hand, intermediate geochemical signatures relative to those of other Dariganga volcanic rocks, and, on the other hand, lower Pb isotope ratios.

Abstract Tangkuban Parahu Volcano, located in Cikahuripan, Lembang, West Bandung Regency, West Java, Indonesia, has a geothermal potential. However, this potential is accompanied by geohazard risks, one of which is a volcanic eruption that can interfere with the development of geothermal potential. On February 12, 2022, there was a gust of volcanic gas from Ratu Crater, indicating an increase in volcanic activity after an eruption in 2019.

Long-lived, widespread intraplate volcanism without age progression is one of the most controversial features of plate tectonics. Previously proposed edge-driven convection, asthenospheric shear, and lithospheric detachment fail to explain the ~5000-km-wide intraplate volcanic province from eastern Australia to Zealandia. We model the subducted slab volume over 100 million years and find that slab flux drives volcanic eruption frequency, indicating stimulation of an enriched mantle transition zone reservoir.

The formations form a composite volcanic edifice that was erupted and grew within a large, volcanic–tectonic subsidence structure (hosting the deposits) that developed within a rifted-arc environment. The formations are evidence of resurgent effusive volcanism and subsidence following a hiatus in volcanism marked by or
