The Campania Ignimbrite eruption (CI – 39 ka) is of the most explosive super-eruptions of the last 200 ka in Europe, that generated about 250-300 km3 of ignimbrite deposit venting from fissural faults of the Campania Plain, southern Italy. The pyroclastic deposits associated to this event show different lithofacies from the vent to the medial-distal part reflecting changing in style of deposition and/or palaeo-environmental setting. Based on some 1000 stratigraphic well logs and previous studies, a qualitative restoration was made of the morphology of the Campania Plain, prior to the CI eruption. According to our interpretation, from the proximal area towards NNW, four main palaeogeographic domains can be recognized, which conditioned the medial/distal distribution of the CI lithofacies and their depositional and early diagenetic environments across the plain.
