Tectonic evolution of the western margin of Gondwana inferred from syntectonic emplacement of Paleozoic granitoid plutons in northwest Argentina
(University of Chicago Press, 2007-03)
The Cerro Durazno, Brealito, and Cobres granitoid plutons belong to the eastern Ordovician magmatic belt of northwestArgentina and are associated with a network of NW- and N-striking ductile shear zones. A structural ...
Structure, emplacement mechanism and magma-flow significance of igneous fingers – Implications for sill emplacement in sedimentary basins
(Pergamon-Elsevier Science Ltd, 2019-07)
Field and seismic observations show that numerous sills exhibit lobate morphologies. Each lobe corresponds to a distinct igneous segment exhibiting a finger-like shape, the long axis of which is commonly interpreted as a ...

Internal structure of the Late Triassic Central Patagonian batholith at Gastre, southern Argentina: Implications for pluton emplacement and the Gastre fault system
(Geological Society of America, 2017-10)
The Central Patagonian batholith (CPB) comprises two Late Triassic calcalkaline plutonic suites (the Gastre superunit of 221 ± 2 Ma and the Lipetrén superunit of 215 ± 1 Ma) which have been interpreted as a record of major ...
