The complex dynamics of gas percolation in low-porosity, crystal-rich silicic magmas

Key Points

The aim is to understand how gas channels develop in low-porosity, crystal-rich silicic magmas.
Observation of bubble textures to track evolution of gas channels.
Analysis of gas and crystal content in immobile magmas.
Study of bubble coalescence dynamics and its relationship with phenocrysts.
Identified dynamic relationship between bubble coalescence and crystal content.
Observed that phenocrysts promote the formation of gas passageways but can also lead to their failure.

Abstract

• The development of gas channels in immobile magmas depends on multiple factors. • Bubble coalescence is a dynamic process controlled by gas and crystal content. • The evolution of channelling can be tracked by observing bubble textures. • Phenocrysts facilitate permeable chains formation but ultimately cause their rupture.
