The purpose of this field guide is to provide an introduction to the geology and paleontology of the lower Paleozoic of the Precordillera Geological Province (Furque & Cuerda, 1979). Central and Western Precordillera settings at Talacasto, La Invernada, and Jáchal River sections, located at the central and northern part of the San Juan Province, are considered. The approximate distance of the cited sections from San Juan City is as follows: Talacasto, 70 km; La Invernada, 110 km, and Jáchal River, 170 km, respectively. The most significant sections run across the Jáchal River and Talacasto Creek, exposing a thick pile of lower Paleozoic siliciclastic marine rocks.
