An introduction to the application of X-ray microtomography to the three-dimensional study of igneous rocks
Imaging rocks in three-dimensions through X-ray microtomography enables routine
visualization of structures in samples, which can be spatially resolved down to the sub …

Textural studies of vesicles in volcanic rocks: an integrated methodology
Vesicles in volcanic rocks are frozen records of degassing processes in magmas. For this
reason, their sizes, spatial arrangements, numbers and shapes can be linked to physical …

[HTML][HTML] The evolution of pore connectivity in volcanic rocks
Pore connectivity is a measure of the fraction of pore space (vesicles, voids or cracks) in a
material that is interconnected on the system length scale. Pore connectivity is …

Shallow vent architecture during hybrid explosive–effusive activity at Cordón Caulle (Chile, 2011–12): evidence from direct observations and pyroclast textures
In June 2011, an eruption of rhyolite magma began at the Puyehue–Cordón Caulle volcanic
complex, southern Chile. By January 2012, explosive activity had declined from sustained …

Explosive-effusive volcanic eruption transitions caused by sintering
Silicic volcanic activity has long been framed as either violently explosive or gently effusive.
However, recent observations demonstrate that explosive and effusive behavior can occur …

The role of melt-fracture degassing in defusing explosive rhyolite eruptions at volcán Chaitén
Explosive volcanic eruptions of silicic magma often evolve towards non-explosive emissions
of lava. The mechanisms underlying this transition remain unclear, however, a widely cited …

Universal scaling of fluid permeability during volcanic welding and sediment diagenesis
In sedimentary basins and volcanic edifices, granular materials undergo densification that
results in a decrease of porosity and permeability. Understanding the link between porosity …
