A more detailed work using all the information previously reported for these formations will be made. After recognizing the most important boundaries these will be verified by the study of outcrops and cores of the corresponding formations. These will result in a model that will show and explain how the middle Tertiary limestone ramp developed over time and its relationship in global terms.
Using sequence stratigraphy it will be possible to develop a diagram of sea level changes in both, local and regional terms. For this study the units that will be used are the Lares Limestone, Montebello Limestone Member of the Cibao Formation, Aguada (Los Puertos) Limestone, Aymamón Limestone, and the Quebradillas Limestone, following the nomenclature of the USGS (1992).
