The Pueblo Viejo district was mapped by Bowin (1966) who described the Los Ranchos and Maimón Fms. and the Hatillo Limestone (Fig. 1 B). He established a Cretaceous age for these rock units and published a regional map covering an area of 5000 km 2.. Kesler and Galbraith (1973) divided the Los Ranchos Fm. into four members …

It is 50 to 75 m wide and 700 m long, with over 500 m vertical extension. Limestone hosts semi-massive sulphide mineralisation. Reef and open platform limestone facies forms the lower part of the basin rift sequence, comprising several partially developed or eroded shallowing-upward carbonate cycles, commonly separated by diastems.
