“…Averaged over million‐year timescales, undecompac‐ted sediment‐accumulation rates decreased 50% from 68 ± 12 m Myr −1 between 3.7 and 3.0 Ma to 35 ± 8 m Myr −1 from 3.0 to 2.1 Ma, and then, remained at 33 ± 7 m Myr −1 until 0.8 Ma. These sediment‐accumulation rates are an order of magnitude lower than sediment‐accumulation rates in other intermontane basins in the Eastern Cordillera of Argentina (Bywater‐Reyes et al ., ; Schoenbohm et al ., ) and Andean foreland basins (Reynolds et al ., , ; Echavarria et al ., ; Horton, ; Uba et al ., ; DeCelles et al ., ; Galli et al ., ), but are comparable to the rates from intermontane basins in the Bolivian Eastern Cordillera (Horton, ). Similar to other intermontane basins in the Eastern Cordillera of Argentina (Bywater‐Reyes et al ., ; Schoenbohm et al ., ), no clear correlation exists between the accumulation rates and average grain size within the basin.…”

“…That this later phase of deformation produced relatively minor uplift of the Sierra Alta may also explain why the rates of sediment accumulation in the Casa Grande basin are nearly an order of magnitude lower than in the Humahuaca basin and other intermontane basins in the Eastern Cordillera (e.g. Bossi et al ., ; Bywater‐Reyes et al ., ; Galli et al ., ; Schoenbohm et al ., ).…”

“…For example, uplift of the Luracatao Range in the Angastaco area at ca. 25.5°S lat, prevented eastward sediment transport by 20 Ma (Coutand et al., ; Deeken et al., ; Galli et al., ). Similarly, the Cachi Range, immediately to the northeast, experienced rapid exhumation and uplift by at least 15 Ma (Deeken et al., ; Pearson et al., , ).…”

“…Las fallas directas pertenecientes a los limites depocentrales del rift presentan grandes espesores de sinrift en sus adyacencias, y los sectores donde los depósitos de sinrift son escasos o nulos y los depósitos de postrift yacen directamente sobre el basamento epimetamórfico marcan los altos estructurales presentes para los tiempos cretácicos (Mon y Salfity, 1995). El estudio de los depósitos de antepaís y sus discordancias internas (del Papa et al, 2013b;Hongn et al, 2008) permitió realizar interpretación acerca de la evolución tectónica del área durante la inversión cenozoica (Carrapa et al, 2012;del Papa et al, 2013;Galli et al, 2014; entre otros).…”

“…Carrapa et al (2011), a partir muestras del Subgrupo Santa Bárbara tomadas en el Norte del cerro Tin Tin, indican que su exhumación (o la exhumación de esta unidad para el sector medio-Norte del Valle Calchaquí) ocurrió entre los 6-12 Ma (Mioceno Medio a Superior). Por último, Galli et al (2014) describen la presencia de clastos de la Formación Yacoraite y del Subgrupo Pirgua en los conglomerados de la Formación San Felipe (unidad superior del Grupo Payogastilla, de edad Plio-Pleistoceno), y sugieren una importante actividad tectónica durante su depositación. Esto también indicaría la edad aproximada de exhumación de estas unidades del Grupo Salta en el sector medio del Valle Calchaquí.…”
