DOI: 10.1016/j.jsames.2018.02.006
Abstract: Abstract In the Famatina range, Sierras Pampeanas of Argentina (SW Gondwana), subvertical calc-alkaline lamprophyric dike swarms crop out through >300 km. The dikes cut Ordovician units with a prominent NW-SE trending and are covered by continental… read more here.

DOI: 10.1016/j.jsames.2021.103432
Abstract: Abstract A Silurian regional tectonometamorphic event has been widely recorded by different geochronological methods in the Sierras Pampeanas, NW Argentina and the Precordillera. It took place between ca. 445 and 420 Ma after the regional Hirnantian… read more here.
