The revision of the stratigraphic record of the borehole Circus Maximus, carried out in 1938 - 1939 by AGIP for the Autarkic Exhibition of Italian Mineral in Rome from the ground level at 18 m a.s.l. up to 1300 m, allows to refer the upper part of the stratigraphic record to the middle Pleistocene p. p. Valle Giulia Formation and Fosso della Crescenza Formation of alluvial and marsh environments and the last 390 m, consisting of conglomerates, to the Messinian - lower Pliocene formations of fan delta and/or alluvial fan environment outcropping in the valleys of rivers Sacco, Ausente and Liri in south - eastern Lazio and in the Tolfa Mountains in north - western Lazio
