A neoproterozoic age for the chromitite and gabbro of the Tapo Ultramafic Massif, Eastern Cordillera, Central Peru, and its tectonic implications [PDF]

open access: yes, 2011
The ultramafic-mafic rocks of the Tapo Complex are exposed in the Eastern Cordillera of the Central Peruvian Andes. This complex is composed of serpentinised peridotites and metabasites with some podiform chromitite lenses and chromite disseminations and

Why is there no Coastal Cordillera at the Arica Bend (Western Central Andes)? [PDF]

open access: yesBasin Research, 2016
AbstractThe architecture of the Western Andes is remarkably constant between southern Peru and northern Chile. An exception, however, is present near Arica at 18°S, where the Andes change their strike direction by ca. 50° and the Coastal Cordillera is absent over an along‐strike width of 50 km.

Active faulting in the central Betic Cordillera (Spain): Palaeoseismological constraint of the surface-rupturing history of the Baza Fault (Central Betic Cordillera, Iberian Peninsula) [PDF]

open access: yesTectonophysics, 2018
This paper on the Baza Fault provides the first palaeoseismic data from trenches in the central sector of the Betic Cordillera (S Spain), one of the most tectonically active areas of the Iberian Peninsula. With the palaeoseismological data we constructed time-stratigraphic OxCal models that yield probability density functions (PDFs) of individual ...

Description of six new species of Xenorhina Peters, 1863 from southern Papua New Guinea (Amphibia, Anura, Microhylidae) [PDF]

open access: yesZoosystematics and Evolution, 2021
We describe six new species of the microhylid frog genus Xenorhina from the southern slopes of Papua New Guinea’s central cordillera and adjacent lowlands, based on a combination of morphological (including osteology) and bioacoustic features. All of the

Insights of Active Extension Within a Collisional Orogen From GNSS (Central Betic Cordillera, S Spain) [PDF]

open access: yes, 2023
The coexistence of shortening and extensional tectonic regimes is a common feature in orogenic belts. The westernmost end of the Western Mediterranean is an area undergoing shortening related to the 5 mm/yr NNW‒SSE convergence of the Nubia and Eurasia ...
