Fluidal pyroclasts reveal the intensity of peralkaline rhyolite pumice cone eruptions

Abstract

Dynamics of peralkaline rhyolite eruptions remain elusive due to the lack of direct observations. Here the authors provide X-ray Computed Tomography, thermal modelling and field data of fluidal shaped pyroclasts and show that peralkaline rhyolite pumice cones are the product of moderate to intense eruptions.
