Tephrochronology and geochemical correlation of Middle Pleistocene distal tephra deposits in Armenia

Autor: Edmond Grigoryan, Khachatur Meliksetian, Hripsime Gevorgyan, Ivan Savov, Gevorg Navasardyan, Marina Bangoyan, Tatevik Boyakhchyan

Widespread volcanism played significant role in geological history of Anatolian-Armenian-Iranian orogenic plateau formed as a result of continental collision of Arabian and Eurasia. Among diverse chemical compositions and eruption styles, reported fo

Autor: Ralf Halama, Ruben Jrbashyan, Osamu Ishizuka, Charles B. Connor, Hripsime Gevorgyan, Laura Connor, Gevorg Navasardyan, Khachatur Meliksetian, Ivan P. Savov, Edmond Grigoryan

Large (VEI= 4-6) Quaternary explosive eruptions have repeatedly occurred in Armenia and the neighboring territories. Worth noting are the Plinian eruptions of Aragats stratovolcano (4096m), located in the vicinity of the Armenian capital city Yerevan

Digitization of the multi-compositional Storkwitz carbonatite diatreme (Delitzsch Complex, Germany)

Autor: Sascha Schmidt, Manuel Lapp, Hripsime Gevorgyan, Ilja Kogan

The Storkwitz diatreme is a multiphase composite body within the Late Cretaceous Delitzsch Complex in north-western Saxony, Germany. The lithology of the Delitzsch Complex varies from rauhaugite and fenite aureole to ultramafic and alkaline lamprophy

Mineral assemblages and xenolith cargo in the Storkwitz carbonatite (Delitzsch Complex, Germany)

Autor: Sascha Schmidt, Hripsime Gevorgyan, Ilja Kogan, Manuel Lapp

The multi-compositional carbonatite body of Storkwitz is one of several purported diatremes of the Late Cretaceous Delitzsch Complex, which comprises carbonatites and ultramafic lamprophyres emplaced into a heterogeneous series of volcanic and sedime

Decoding a post-collisional multistage magma system: The Quaternary ignimbrites of Aragats stratovolcano, western Armenia

Autor: Hripsime Gevorgyan, Arsen Israyelyan, Christoph Breitkreuz, Alexander Repstock, Bernhard Schulz, Khachatur Meliksetian

Publikováno v: Lithos. :267-282

Quaternary eruptions from an intraplate multistage magma reservoir of the Aragats stratovolcano in western Armenia formed pyroclastic density currents and fallouts deposited in an area around 2,000 km2, comprising six ignimbrite units and three fallo

Quaternary ring plain- and valley-confined pyroclastic deposits of Aragats stratovolcano (Lesser Caucasus): Lithofacies, geochronology and eruption history

Publikováno v: Journal of Volcanology and Geothermal Research. 401:106928

Aragats stratovolcano, located on the South Armenian block, a micro-plate in the Arabian-Eurasian collision zone, has a complex and long-lasting Quaternary eruption history. Cataclysmic eruptions formed widespread pyroclastic deposits, which are inte

Publikováno v: Journal of Volcanology and Geothermal Research. 402:106982

Voluminous early to middle Pleistocene pyroclastic flow deposits were generated from Mount Aragats (Aragats Volcanic Province, AVP), one of the largest volcanoes in the Arabia-Eurasia continental collision zone. Here we report paleomagnetic results,
