Abstract: During the researches being carried out in the M. Cairo Massif (Southern Lazio, Italy) the AA. observed sinsedimen­tary breccias widely outcropping on the north-eastern sector of the area. The breccias are well bedded, show a variable thicke­ness and a wedge-shaped geometry; they are made up of coarse angular fragments which are not graded, without any sorting, varyng in lithology and age. The above characters suggest a local derivation from the mesozoic sequence. The breccias overlie a substratum formed of limestones of variable age, going from the Dogger-Malm (as, for exam­ple, the Costalunga area) to Barremian (San Vincenzo and Vallone Scuro areas). Organic detrital limestones known as "Calcare sac­caroide" Auct., the age of which goes from Campanian­Mastrichtian to Paleogene, conformably lie on the brec­cias. The lithostratigraphic and biostratigraphic data so far obtained enable us to formulate some hypotheses on the age and the mechanisms by which these breccias were empla­ced.
