Internal structure of the Late Triassic central Patagonian Batholith at Gastre, southern Argentina; implications for pluton emplacement and the Gastre fault system

The Central Patagonian batholith (CPB) comprises two Late Triassic calcalkaline plutonic suites (the Gastre superunit of 221 ± 2 Ma and the Lipetren superunit of 215 ± 1 Ma) which have been interpreted as a record of major dextral motion along the transcontinental NW-SE-striking subvertical Gastre f...
