Dynamics of large pyroclastic currents inferred by the internal architecture of the Campanian Ignimbrite

, 2020
Large ignimbrites are the product of devastating explosive eruptions that have repeatedly impacted climate and life on global scale. The assemblage of vertical and lateral lithofacies variations within an ignimbrite sheet, its internal architecture, may ...

Marine emplacement of welded ignimbrite: the Ordovician Pitts Head Tuff, North Wales

, 2000
The Pitts Head welded ignimbrite records a subaerial, large‐volume eruption and associated pyroclastic current that flowed into the sea. The current 15 km from source was steadily sustained with high mass flux and high particle concentration towards its ...

Reasons of different colors in the ignimbrite lithology: Micro-XRF and confocal Raman spectrometry method

, 2008
Medium to large volume ignimbrites usually show vertical changes in terms of color, mineral components, texture and geochemistry. Determination of vertical changes in single extensive ignimbrite flow unit is difficult and requires careful studies.

Pyroclastic deposits and volcanic history of Mayor Island

, 1981
The emergent summit of Mayor Island, Bay of Plenty, New Zealand, is a peralkaline rhyolite volcano constructed by: a sequence of lava flows, the Tutaretare Rhyolite Formation(new); and pyroclastic deposits, the Oira Pyroclastite Formation (new).

Petrogenesis of the Sólheimar ignimbrite (Katla, Iceland): Implications for tephrostratigraphy

, 2012
The Sólheimar ignimbrite was one of the largest eruptions from the Katla caldera (Iceland) and is important for tephra studies in the North Atlantic because of its possible linkage with the Vedde Ash, a compositionally bimodal tephra layer used for ...

A submarine welded ignimbrite - crystal-rich sandstone facies association in the Cambrian Tyndall Group, western Tasmania, Australia

, 1997
Three occurrences of rhyolitic welded ignimbrite are intercalated within a submarine, below-storm-wave-base sedimentary succession in the Cambrian Tyndall Group, Mount Read Volcanics, western Tasmania.

Usability of ignimbrite powder in reactive powder concrete road pavement

, 2017
In this study, reactive powder concrete (RPC) was used as the concrete for rigid pavement. In the production of RPC, one of the materials that increases the cost is cement.
