Mid-Late Devonian assemblages of herbaceous lycophytes from northern Argentina and Bolivia: Age assessment with palynomorphs and invertebrates and paleobiogeographic importance
(Pergamon-Elsevier Science Ltd, 2015-11)
Implications of a new collection of lycophytes of the genera Haplostigma Seward and Paleostigma Kräusel and Dolianiti from southern Bolivia and northern Argentina are presented. Fragmented herbaceous stems of lycophytes ...
The phacopid trilobite Echidnops taphomimus n. sp. from the Lower Devonian of Argentina: Insights into infaunal molting, eye architecture and geographic distribution
(Paleontological Society, 2016-11)
Some Silurian-Devonian Argentinian trilobites characterized by infaunal behavior during molting are considered. After a taxonomic reappraisal, a species previously referred to a lineage of the phacopid Paciphacops is ...
The unusual record of Nereites, wrinkle marks and undermat mining trace fossils from the late Silurian-earliest Devonian of central-western margin of Gondwana (Argentina)
(Elsevier Science, 2015-12)
Silurian-Devonian deposits of central western Argentina contain one of the most diverse Palaeozoic records of Nereites in Gondwana. Nereites cf. cambrensis, Nereites irregularis?, Nereites jacksoni, Nereites macleayii, ...
Palaeomagnetism of the Late Devonian-Early Carboniferous Achala Batholith, Córdoba, central Argentina: Implications for the apparent polar wander path of Gondwana
(Elsevier Science, 2008-03)
The Achala Batholith (31°30′S, 64°45′W, Córdoba, Argentina) is a major magmatic complex of the Sierras Pampeanas, emplaced as a post-orogenic pluton in a metamorphic-plutonic basement. It is mainly a porphyritic to ...
Devonian palynological assemblages from the San Antonio x-1 Borehole, Tarija Basin, northwestern Argentina
(Universidad de Barcelona, 2011-05)
The palynological analysis of the 2548-3628 m interval of the San Antonio x-1 Borehole in northwestern Argentina is presented. The illustrated palynoflora is composed of 96 species represented by diverse palynological ...
Structural setting of the Chanic orogen (Upper Devonian) at central-western Argentina from remote sensing and aeromagnetic data. Implications in the evolution of the proto-Pacific margin of Gondwana
(Pergamon-Elsevier Science Ltd, 2018-12)
The basement of the Central Andes located in central-western Argentina (31º20′S - 69º22′W) is composed by the Cuyania and Chilenia terranes which were amalgamated to Gondwana in the Early-Mid Paleozoic. Between the ...

The mafic-ultramafic belt of the Argentine Precordillera: A geological synthesis
(Pergamon-Elsevier Science Ltd, 2021-10)
In central-western Argentina, a mafic-ultramafic belt occurs throughout the western margin of the Precordillera. This belt is interpreted as the suture zone between the Cuyania terrane and the Chilenia terrane, both accreted ...
The collision of patagonia: Geological facts and speculative interpretationsLa colisión de patagonia: Evidencias geológicas e interpretaciones especulativas
(Asociación Paleontológica Argentina, 2020-10)
The Paleozoic evolution of Patagonia was the focus of controversies between its allochthonous or autochthonous origin. The arrival of plate tectonics supported new allochthonous alternatives and from an initial fixist ...
