The reinterpretation of Leone Lake sediments as a pyroclastic surge deposit and its tectonic significanceThe Leone Lake sediments, previously interpreted as being of fluvial and lacustrine origin, are reinterpreted as subaerial pyroclastic surge and palagonite tuff cone deposits. This conclusion is based on bedforms, particle morphology, the primary mineral assemblage, and the nature and mineralogy of the alteration. The principal characteristics of the pyroclastic surge units and palagonite tuffs are examined, and the tectonic significance of the reinterpretation is briefly discussed.
