Abstract
Delicate feathery terminations and locally preserved vesicles indicate that the fiamme are altered compacted pumice clasts. The presence of bedding-parallel stylolites and solution seams, undeformed shards and pumice clasts adjacent to the fiamme, and the overprinting of fiamme by the regional cleavage suggest that the fiamme formed during diagenesis, prior to tectonic deformation, and that compaction did not involve welding. Fiamme and eutaxitic texture in these examples resulted from the alteration, dissolution and mechanical compaction of cold tube pumice clasts during diagenesis and lithification.
