The basal conglomerate containing foraminiferal limestone pebbles isfound in the vicinity of Rancho Viejo on both sides of Canada RanchoViejo, a few kilometers above the point where it joins Canada Diablo. Thisconglomerate rests directly upon the limestone from which its pebbles arederived. There is clearly an unconformity here, and probably a large limestone is hard, fine-grained, semicrystalline, and massive. No DOMINICAN REPUBLICGeological Survey Memoirs, Vol. I, Pl. XIX. A.
