Pyroclastics (lahars), outcropping in the valley between Monte Acuto and Monte Caccume, originated from phreatomagmatic eruptions and consisting of aggregates of carbonate fragments and lava xenoliths (containing pyroxenes, biotite, garnets, olivine and feldspars) in an ashy matrix cemented by calcite and zeolites (De Gennaro & Franco, 1971). Along the bottom of Fosso di Monte Acuto, the lahars have been highly weathered to form an unlithified reddish unit with a halloysite-10 Å matrix. Most of the minerals from the lahars have been only slightly altered, the exception being biotite, which often shows a partial or complete transformation to vermiculite and, rarely, extreme alteration to smectite (De Gennaro & Franco, 1975; Pozzuoli et al., 1992).
