Changes

There was an influx of quartz- and mica-rich [[Turbidite|turbiditic]] detritus, possibly from the erosion of the previously formed basement high, which formed the La Esperanza, Polier, and Constancia* Formations. A southern Guajaibon–Sierra Azul carbonate bank may have been deposited.

Toward the south, the close of the Early Cretaceous was characterized by a great outpouring of basaltic flows (Matagua* Formation) over rifted basement. This activity was accompanied toward the north and west (Cifuentes*, southern Rosario, northern Rosario, and La Esperanza belts) by abundant and extensive [[chert]] deposits (Calabazar*, Carmita*, and Santa Teresa* Formations).
