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

Pyroclastic density currents (PDCs) are hazardous and destructive phenomena that pose a significant threat to communities living in the proximity of active volcanoes. PDCs are ground-hugging density currents comprised of high temperature mixtures of

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

Abstract The interaction of magma with external water commonly enhances magma fragmentation through the conversion of thermal to mechanical energy and results in an increased production of fine‐grained volcanic tephra. Magma‐water interaction is

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,

Abdominal aortic aneurysm (AAA) is a potentially lethal disease associated with immune activation-induced aortic degradation. We hypothesized that xenotransplantation of human adipose-derived stem cells (hADSCs) would reduce aortic inflammation and a

The breaking apart of magma into fragments is intimately related to the eruptive style and thus the nature and footprint of volcanic hazards. The size and shape distributions of the fragments, in turn, affect the efficiency of heat transfer within py

During explosive eruption of low viscosity magmas, pyroclasts are cooled predominantly by forced convection. Depending on the cooling efficiency relative to other timescales, a spectrum of deposits can be formed. Deposition of hot clasts, above their
