Abstract:
Sector collapse a volcanic edifice is one of the most significant hazards posed by active volcanic systems. Acid-sulphate alteration of the rock mass is one factor that contributes to an increased risk of collapse. This type alteration is characterised by the presence of the mineral alunite, which can form in several distinct environments in the volcanic edifice. These alteration zones possess different geometries, some of which pose a greater risk than others. Textural and geochemical distributions (Ca, Na, Sr, P, Ba, + REE) in alunite show which lithologies have been modified, thus making it possible to determine if the geometry of the alteration zone is one that would be a contributory factor to an increased risk of sector collapse.
