Geology of the Quebrada Honda, basin of Lago La Plata, Chubut

The quebrada Honda is situated in the Lago La Plata-Fontana basin in Chubut. The stratigraphy of the area begins in the Upper Jurassic with the calc-alkaline intermediate to acidic Lago La Plata Formation rocks. The Neocomian Coyhaique Group, which includes the Tres Lagunas and Katterfeld Formations...

description The quebrada Honda is situated in the Lago La Plata-Fontana basin in Chubut.

These units are included in a paleoenviromental model as a shelf-margin system tract followed by a transgressive system tract. The discovery of Favrella americana in the Katterfeld Formation constrains to the Early Hauterivian the age of these sequences.
