UBSU E CARTOGRAFIA GEOLOGICA: PROBLEMI E POTENZIALITÀ DI UTILIZZO DELLE UNITA' A LIMITI INCONFORMI (UBSU) NELL'INTERPRETAZIONE E NELLA RAPPRESENTAZIONE CARTOGRAFICA DEI DEPOSITI VULCANICI QUATERNARI - L'ESEMPIO DEI FOGLI N.RO 451 “MELFI” E N.RO 452 “RIONE

Abstract

: C. Principe & P. Giannandrea, Ubsu inside geological mapping: the use of the unconformity bounded stratigraphic units
in the chartography of the quaternary volcanic deposits - the exemples of melfi (n. 451) and rionero (n.452) areas.
By means of the use of the Unconformity Bounded Stratigraphic Units the sedimentary and volcanic stratigraphic successions outcropping in the area of Mount Vulture volcano (n.451 “Melfi” and n.452 “Rionero in Vulture”) has been subdivided in synthematic units.
Unconformity use hallowed to define two Supersynthems and five Synthems. The synthematic subdivision over passed the limits of the
chartographed area and make possible the correlations of deposits on a wider area. The clear and objective criteria on witch
Sybthematic units are based resulted in an improvement of geological significance and in the volcanological detail of the chartographed areas.
