Paleomagnetic data from the Precordillera of northern Chile: A multiphase rotation history related to a multiphase deformational history

, 2020
One of the most conspicuous features of the Andean chain is the change in its trajectory from NW-SE to N-S at 18°S known as the Bolivian Orocline. Although the Central Andes rotation pattern (CARP) agrees roughly with the geometry of the orocline, large ...

Global Series and Stages for the Ordovician System: A Progress Report

Geologica Acta, 2005
There is no global standard set of chronostratigraphic/geochronologic subdivisions for the Ordovician System/Period. British series/epochs are often used as de facto nomenclature on stratigraphic correlation charts and geologic time scales. However, they

New conodont records of the Los Sombreros Formation (Cambrian-Ordovician) from the Western Precordillera, Argentina: Biostratigraphic and palaeoenvironmental implications

, 2019
The presence of a carbonate platform that interfingers towards the west with slope facies allows for the identification of an ancient lower Palaeozoic continental margin in the Western Precordillera of Argentina.

Distribution of landslides along the Andean active orogenic front (Argentinean Precordillera 31–33° S)

Quaternary International, 2019
As one of the main environmental effects of earthquakes, the distribution of landslides could reflect regional neotectonic activity. To that end, we carried out an inventory of landslides along the Precordillera range (31°-33°S) comprising the most ...
