Stratigraphy of the Cuevo (Permian-Lower Triassic) and Tacurú (Jurassic) Groups along the Bermejo river (Orán, Salta, and Tarija, Bolivia)

A detailed study of the Cuevo and Tacurú Groups along the Bermejo̧ river (Argentina/Bolivia, boundary) focussed on the late Palaeozoicand early Mesozoic sequences of Sierras Subandinas. The sedimentary environments were deduced from the study of facies and sedimentary structures. The lower units of...
