The interaction of the northern Nazca and southwestern Caribbean oceanic plates with
northwestern South America (NWSA) and the collision of the Panama‐Choco arc (PCA) …

Collision with and subduction of an oceanic plateau is a rare and transient process that
usually leaves an indirect imprint only. Through a tectonostratigraphic analysis of pre …

We used the receiver function technique to deduce crustal thickness beneath the
northwestern Andean system, using data from the permanent seismic network of Colombia …

New maps of S velocity variation for the upper and middle crust making up the northwestern
most corner of South America have been developed from cross correlation of ambient …

Earthquake hypocenter relocations, earthquake focal mechanisms, P-wave velocity anomaly
tomography, interpretation of deep-penetration seismic reflection lines, and gravity modeling …

The cause of tectonic deformation in northwestern South America and its link to upper
mantle structure and flow are debated. We use a combination of broadband and short period …

New geochronologic, thermochronologic, and geomorphometric landscape analyses were
performed to discriminate the relationships between tectonics and geomorphology in the …

Abstract The late Oligocene-middle Miocene Amagá Formation is a continental siliciclastic
succession deposited along several semi-isolated intramontane sedimentary basins in the …

Using hypocentral solutions and arrival times of first P and S waves recorded by stations of
the Red Sismológica Nacional de Colombia (RSNC), as well as GPS, gravity, and magnetic …

This paper presents new geochemical and geochronological data of the Late Mesozoic
volcanic rocks in East Mongolia. These volcanic rocks belong to high‐K calc‐alkaline and …
