The stratotype of the Margot Formation was previously established at the Mina Margot in the Matanzas Province of western Cuba. The limestone interbeds occurring between the basalts of the upper part of this formation contain Turonian planktonic foraminifers. Late Cretaceous age and tectonic position of the Margot Formation in the Palaeogene thrust nappes exposed in the northwestern Matanzas Province suggest the Caribbean plateau origin of the basalts occurring in this unit. According to an alternative interpretation, the Margot Formation represents a fragment of the section of the proto-Caribbean Oceanic crust, mainly of Cenomanian-Turonian age.
