Schematic cross-section through a maar-diatreme (upper diagram) and a tuff ring (lower diagram), showing the typical volcano-sedimentary processes, deposits and geomorphological features. Note that the left-hand side represents the characteristics of a maar-diatreme volcano formed in a hard-substrate environment, while the right-hand side is a soft rock environment. (Abbreviation: PDC = pyroclastic density current).
