Geochemical variations in igneous rocks of the Central Andean orocline (13°S to 18°S): Tracing crustal thickening and magma generation through time and space
Compositional variations of Central Andean subduction-related igneous rocks reflect the plate-tectonic evolution of this active continental margin through time and space. In order to address theExpand

Late Oligocene-early Miocene major tectonic crisis and related basins in Bolivia
Recent advances in biochronology, geochronology, magnetostratigraphy, structural geology, and basin analysis make untenable the traditional correlation of the first major Andeanage deformationalExpand

Stratigraphy and chronology of Upper Cretaceous–lower Paleogene strata in Bolivia and northwest Argentina
Integration of sequence stratigraphy, magnetostratigraphy, Ar/Ar dating, and paleontology considerably advances knowledge of the Late Cretaceous–early Paleogene chronostratigraphy and tectonicExpand

Phanerozoic Evolution of Bolivia and Adjacent Regions
The geologic evolution of Bolivia and the central Andean system during the past 500 m.y. was largely controlled by the geodynamics of the South American margin of western Gondwana. The PhanerozoicExpand

Counterclockwise rotation of late Eocene–Oligocene fore‐arc deposits in southern Peru and its significance for oroclinal bending in the central Andes
The results of a paleomagnetic study along the fore arc of southern Peru (15­18°S) and northern Chile (18­19°S) are reported from middle to late Miocene ignimbrites (7 sites), late Oligocene to earlyExpand

Late Permian–Middle Jurassic lithospheric thinning in Peru and Bolivia, and its bearing on Andean-age tectonics
Abstract Integrated studies and revisions of sedimentary basins and associated magmatism in Peru and Bolivia (8–22°S) show that this part of western Gondwana underwent rifting during the LateExpand

Chronostratigraphy of the mammal-bearing Paleocene of South America
Abstract Land mammal faunas of Paleocene age in the southern Andean basin of Bolivia and NW Argentina are calibrated by regional sequence stratigraphy and magnetostratigraphy. The local fauna fromExpand

Direction and timing of uplift propagation in the Peruvian Andes deduced from molecular phylogenetics of highland biotaxa
Abstract Physical paleoaltimetric methods are increasingly used to estimate the amount and timing of surface uplift in orogens. Because the rise of mountains creates new ecosystems and triggersExpand

A northward colonisation of the Andes by the potato cyst nematode during geological times suggests multiple host-shifts from wild to cultivated potatoes.
The cyst nematode Globodera pallida is a major pest of potato in South America where this specialist parasite is native. To investigate its phylogeography, we have genotyped individuals from 42Expand

Middle Maastrichtian vertebrates (fishes, amphibians, dinosaurs and other reptiles, mammals) from Pajcha Pata (Bolivia). Biostratigraphic, palaeoecologic and palaeobiogeographic implications
The Pajcha Pata fossil locality in south central Bolivia, in the upper part of the Lower Member of the El Molino Formation, is the first late Cretaceous fauna in South America which has yielded, inExpand
