Sono state studiate le associazioni ad ostracodi, foraminiferi, briozoi e serpulidi ris-contrate in una successione sedimentaria pleistocenica, affiorante in località "Cartiera Molino” nei pressidi Vittoria (RG), lungo la riva destra del Fiume Ippari. L'analisi faunistica effettuata lungo la sezione haconsentito di definire l'evoluzione pleistocenica del settore sud-occidentale del Plateau Ibleo (area diComiso-Vittoria) da paleoambienti marini del piano infralitorale, testimoniati nei livelli basali dellasuccessione, ad ambienti progressivamente meno profondi di transizione e salmastri, testimoniati neilivelli intermedi, fino ad ambienti francamente dulcicoli individuati nei livelli sommitali della sezione.

Abstract
Faunistic associations of the Lower Pleistocene sediments, out-cropping at Cartiera Molinoalong the true right bank of the Ippari River (Vittoria, SE Sicily), have been investigated. This study integrates data obtained from the analysis of ostracods, foraminifers, bryozoans and serpulids foundwithin a six metre thick sedimentary section. This multiproxy approach allowed us to reconstruct thepalaeoenvironmental evolution of this south-western sector of the Hyblean Plateau (Comiso-Vittoriaarea) from fluvially-influenced shallow marine settings, recorded in the lower portion of the succession,to progressively shallower, transitional and brackish environments, testified in mid levels, up to freshwater environments at the top of the section.File | Dimensione | Formato | |
