Summary:

The Aguas Buenas limestone of Semmes (1919) is correlated with limestone in the Comerio quad. and is revised as the Aguas Buenas limestone member, the basal lenticular limestone of informal formation K near Cidra. Basal strata of formation K adjoin stratigraphically equivalent strata of formation D in the Cayey quad.

O1-O31., Prepared in cooperation with the Commonwealth of Puerto Rico Economic Development Administration


Summary:

Aguas Buenas Limestone Member is here redefined, removed from the Fajardo Formation, and assigned to the base of the Torrecilla Breccia. Type locality designated where 30 m of dark-gray finely crystalline, lenticular, reef limestone with rudist and gastropod fauna are exposed. Overlies hydrothermally altered volcanic rock; top is faulted out at type locality, but nearby it is overlain by sandstone and siltstone that grade into volcanic strata of the Torrecilla. Age is Early Cretaceous, probably Albian, based on fossils.
Type locality: quarry (Puerto Rico Meter Grid System 183,640 E.; 41,430 N.) on northwest side of Quebrada la Zapera, 4.1 km north-northeast of Cidra, Comerio quadrangle, north-central Puerto Rico.
Type area: in zone of well-developed karst topography, in Barrio Sumidero, about 3 km due south of Aguas Buenas, Comerio quadrangle, north-central Puerto Rico.

Summary:

The Aguas Buenas Limestone Member of the Torrecilla Breccia occurs in central PR. Member is defined as minor limestone within the formation. The Aguas Buenas is of Early Cretaceous age.
