Abstract Mantle-derived xenoliths entrained by low viscosity magmas indicate transport through great thicknesses of orogenic (≲50-80 km) and cratonic ( $$\lesssim$$ ≲ 20 km) mantle lithosphere. The size and density of xenoliths dictate that, rela

Jones et al. identify a new type of volcanic deposit, inflated pyroclasts, that form by continued gas expansion post-deposition. They show how these deposits can be indicative of abrupt transitions in eruptive behaviour at mafic volcanoes.

The pyroclast properties and features can provide insights into the dynamics of explosive eruptions of low viscosity magma. Here, the authors show how lava droplets, or pyroclasts are subject to melt removal and melt addition during transport in a ga

In contrast to water and air, ice is the most dynamic enveloping medium and unique environment for volcanic eruptions. While all three environments influence volcanic activity and eruption products, the cryospheric eruption environment is unique beca

Despite having relatively short timespans of eruptions, monogenetic volcanoes can pose significant risks to the nearby population. Here, we describe the ∼1700 CE eruption of Tseax volcano, British Columbia, which killed up to 2,000 people of the Ni

Monogenetic volcanoes are characterized as having no temporal break in eruptive activity and are often assumed to have a simple (singular) magmatic plumbing system. However, recent studies on monogenetic systems have started to recover evidence of co

Kimberlite magmas transport cratonic mantle xenoliths and diamonds to the Earth's surface. However, the mechanisms supporting the successful and efficient ascent of these cargo-laden magmas remains enigmatic due to the absence of historic eruptions,

FOAMGLAS® is a closed-cell glass insulation that has a high porosity, is impermeable, and can be heated above its glass transition temperature (Tg) without fracturing. Here, we characterize, using standard laboratory techniques, the thermal and tran

Here we explore and review some of the latest ideas and applications of Raman spectroscopy to the volcanological sciences. Firstly, we provide a brief overview of how Raman spectral analysis works and how spectra from silicate glasses are interpreted

Super-eruptions generating hundreds of cubic kilometres of pyroclastic density currents are commonly recorded by thick, welded and lava-like ignimbrites. Despite the huge environmental impact inferred for this type of eruption, little is yet known ab
