Cuesta del Cura Limestone
Cuesta del Cura Limestone exposed at Los Chorros Canyon of highway
57 (monterrey-Saltillo-San Luis Potosi). This was the outcrops exposed
before the recently reconstruction of the highway. Note the prattle, evenly
bedded, continuous stratification of the limestone layers. Chert layers
and bands are abundant and irregularly distributed throughout the unit.
This limestone are pelagic biomicirtes containing abundant planktics and
calcified radiolarians. Disharmonic folding is a common feature
of the Cuseta del Cura Limestone.
