Revised Minoan eruption volume as benchmark for large volcanic eruptions [PDF]
Despite their global societal importance, the volumes of large-scale volcanic eruptions remain poorly constrained. Here, we integrate seismic reflection and P-wave tomography datasets with computed tomography-derived sedimentological analyses to estimate

Permian Large Igneous Provinces and Their Paleoenvironmental Effects
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The ignimbrites of Terceira, Azores [PDF]
On the oceanic islands of the Atlantic ignimbrites are known to occur on Iceland, Gran Canaria, Tenerife and on two of the Azores islands, Terceira and São Miguel. Ignimbrite may form a larger proportion of the total volume of rock on the island of Terceira than it does on any of the other islands, yet the individual eruption volumes are small (≤ 1 km³)

Correlation of ignimbrites using characteristic remanent magnetization and anisotropy of magnetic susceptibility, Central Andes, Bolivia [PDF]
Large ignimbrite flare-ups provide records of profound crustal modification during batholith formation at depth. The locations of source calderas and volumes and ages of the eruptions must be determined to develop models for the tectonomagmatic processes

Grain-size distribution of volcaniclastic rocks 1: A new technique based on functional stereology [PDF]
The power of explosive volcanic eruptions is reflected in the grain size distribution and dispersal of their pyroclastic deposits. Grain size also forms part of lithofacies characteristics that are necessary to determine transport and depositional ...

The origin of a zoned ignimbrite: Insights into the Campanian Ignimbrite magma chamber (Campi Flegrei, Italy) [PDF]
Abstract Caldera-forming eruptions, during which large volumes of magma are explosively evacuated into the atmosphere from shallow crustal reservoirs, are one of the most hazardous natural events on Earth. The Campanian Ignimbrite (CI; Campi Flegrei, Italy) represents a classical example of such events, producing a voluminous pyroclastic sequence of ...
