, 2022 Pyroclastic density currents (PDCs), alongside other density currents (i.e. turbidity currents, lahars, dust storms or avalanches), are principal mechanisms for lateral sediment transport across varying landscapes.

STREAM GRADIENT INVESTIGATION IN THE BÜKKALJA USING INTERPOLATED SURFACES [PDF]
Acta Geographica Debrecina. Landscape & Environment Series, 2010 The geological, tectonic settings of an area can be examined with the analysis of drainage network. In the Bükkalja, the Miocene pyroclasts – mainly the welded ignimbrites – had taken decisive part in theevolution of drainage network.

Sedimentation and mobility of PDCs: a reappraisal of ignimbrites’ aspect ratio
Scientific Reports, 2017 The aspect ratio of ignimbrites is a commonly used parameter that has been related to the energy of the parent pyroclastic density currents (PDCs). However this parameter, calculated as the ratio between the average thickness and the average lateral ...

Volcanica, 2022 Caldera-forming eruptions are amongst the most hazardous events in the Earth’s history, and understanding their formation is essential to forecasting activity at active calderas worldwide. In this study we present new field and geochronological evidence

Petrology of Badenian ignimbrites, Gutai Mts. (Eastern Carpathians)
, 2012 Gutâi Mts., part of inner Carpathians volcanic arc, consist of products of felsic and intermediate volcanism. The previously known “Badenian Rhyodacitic Formation”, expression of the felsic explosive volcanism, is composed of a well-defined basal unit of

Stratigraphy, structure and geology of Late Miocene Verkhneavachinskaya caldera with basaltic–andesitic ignimbrites at Eastern Kamchatka [PDF]
, 2019 We newly describe a paleovolcano in the Eastern Volcanic Belt of Kamchatka named Verkhneavachinskaya caldera (VC). According to geological mapping of the area covered by the deposits, mainly lava-like ignimbrites, the VC is interpreted as an eroded ...

Paleointensity Estimates From Ignimbrites: The Bishop Tuff Revisited
Geochemistry, Geophysics, Geosystems, 2018 Volcanic ash flow tuffs (ignimbrites) may contain single domain‐sized (titano) magnetite that should be good for recording geomagnetic field intensity, but due to their complex thermal histories also contain other magnetic grains, which can complicate ...

Reconstructing the plinian and co-ignimbrite sources of large volcanic eruptions: A novel approach for the Campanian Ignimbrite [PDF]
Scientific Reports, 2016 AbstractThe 39 ka Campanian Ignimbrite (CI) super-eruption was the largest volcanic eruption of the past 200 ka in Europe. Tephra deposits indicate two distinct plume forming phases, Plinian and co-ignimbrite, characteristic of many caldera-forming eruptions.
