Source of the Glencoe Ignimbrites [PDF]
Nature, 1963 IGNIMBRITES1,2 are a characteristic component of the typically post-orogenic basalt–andesite–rhyolite volcanic association. These pyroclastic deposits are now generally accepted2 as having been produced by eruptions of nuees ardentes in which solid particles, both rock and crystal fragments, glass shards and pumice fragments are suspended by turbulent ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.Abstract Hydrothermal sealing is a mechanism thought to be responsible for challenging‐to‐forecast phreatic and phreatomagmatic eruptions. To better understand this process, we present a study in which we assessed the textural, mineralogical, and physical properties (porosity, permeability, and tensile strength) of blocks of hydrothermal seal that were

Nuées ardentes and Ignimbrites [PDF]
Nature, 1946 A MODERN text-book of volcanology by Prof. C. A. Cotton, published under the somewhat misleading title “Volcanoes as Landscape Forms”1, has recently been reviewed in Nature by Prof. Arthur Holmes2. The book is beautifully illustrated and well documented ; it thus fills a gap in British volcanological literature and is likely to be widely read by ...

Correlation of welded ignimbrites on Pantelleria (Strait of Sicily) using paleomagnetism
, 2011 Although the oldest volcanic rocks exposed at Pantelleria (Strait of Sicily) are older than 300 ka, most of the island is covered by the 45–50 ka Green Tuff ignimbrite, thought to be related to the Cinque Denti caldera, and younger lavas and scoria ...
