Block and Bomb Field of the 1888–1890 CE Eruption at La Fossa Cone (Vulcano, Aeolian Islands): Constraints on Conduit Stratigraphy and Eruptive Dynamics

Geochemistry, Geophysics, Geosystems
Vulcanian eruptions are classically associated with the launch of ballistic ejecta and particularly with the production of breadcrust bombs. Morpho‐textural analysis of these ejecta provides critical insight into the poorly constrained processes ...
