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.

Landscape evolution in ignimbrite terrain : a study of the Mamaku Plateau, Taupō Volcanic Zone, New Zealand. [PDF]
, 2021 Landscape evolution in ignimbrite terrains is complex due to the diverse, heterogeneous nature of ignimbrite deposits. Globally, little landscape evolution research has been conducted on ignimbrite terrains, especially multi-ignimbrite systems.

Reconciling complex stratigraphic frameworks reveals temporally and geographically variable depositional patterns of the Campanian Ignimbrite [PDF]
, 2023 The 39.8-ka Campanian Ignimbrite was emplaced during a large caldera-forming eruption of Campi Flegrei near Naples, Italy. The ignimbrite is found up to 80 km from the caldera, and co-ignimbrite ash-fall deposits occur 3200 km away.

The incrementally zoned Miocene Ayagaures ignimbrite (Gran Canaria, Canary Islands) [PDF]
, 2010 The 20–25 m thick trachyphonolitic Ayagaures ignimbrite cooling unit [(AY); 11.8 Ma] exposed over 250 km2 (onshore volume ca. 4.5 km3 DRE) is the uppermost and most voluminous cooling unit of the Middle Fataga Formation (MFF), part of the Fataga Group ...

Properties of the Ignimbrites in the Architecture of the Historical Center of Arequipa, Peru
Applied Sciences, 2021 The petrographic and petrophysical characteristics of three varieties of ignimbrites used in the architectural heritage of Arequipa (southwest Peru) are analyzed. The modal classification QAFP and TAS diagram discriminate their dacitic nature.

Terra Digitalis, 2019 The Xáltipan ignimbrite records the largest single-eruption of the Trans-Mexican Volcanic Belt up to date (≥344 km3 uncompacted volume). As most large ignimbrites, this ignimbrite presents common challenges when mapping.

Hungarian Geographical Bulletin, 2022 Units with extremely variable erodibility are typical in the succession of pyroclastic-dominated volcanic fields. Welded ignimbrites are usually resistant to erosion, thus, they often appear as positive landforms, i.e., mesas or tilted plateaus after ...
