Abstract

Hummocky cross-stratification (HCS) occurs in two Pliocene progradational nearshore-marine to fluvial sequences. The HCS is notable because of its shallow depth of deposition (~2-5m) and its coarse grain size (up to coarse sand). Individual units of HCS consist of, in ascending order, three subfacies which are characterized by distinctive internal structure: a massive subfacies; a centimeter-scale laminated (meso-laminated) subfacies; and a millimeter-scale laminated (micro-laminated) subfacies. Preservation of the Guardavalle HCS in a very shallow-marine environment was promoted by the microtidal, storm-wave-dominated character of the Pliocene Ionian coast of Calabria. -from Authors
