This paper presents low-temperature thermochronological data and K-Ar fault gouge ages from the Sierra
de San Luis in the Eastern Sierras Pampeanas in order to constrain its low-temperature thermal evolution and exhumation
history. Thermal modelling base...

The Las Lozas volcanic sequence, which crops out at northwestern border of the Famatina belt-southeastern
Puna, NW Argentina, is constituted mainly by rhyolites and a lesser volume of basalts and trachytes, and volcanoclastic
deposits. These rocks, previ...
