Mantle layering across central South America
[1] Imaging of seismic velocity discontinuities along a 3000 km profile across central South America at 20 S suggests that the depth variations of the 410-km (d410) and 660-km (d660) discontinuities are closely associated with the high-velocity Nazca slab and juxtaposed low-velocity oceanic mantle beneath the slab. The mantle transition zone thickness ranges from 220 km in the oceanic mantle to...

متن کاملSpace geodetic observations of nazca-south america convergence across the central andes
Space geodetic data recorded rates and directions of motion across the convergent boundary zone between the oceanic Nazca and continental South American plates in Peru and Bolivia. Roughly half of the overall convergence, about 30 to 40 millimeters per year, accumulated on the locked plate interface and can be released in future earthquakes. About 10 to 15 millimeters per year of crustal shorte...
متن کاملFlying shells: historical dispersal of marine snails across Central America.
The geological rise of the Central American Isthmus separated the Pacific and the Atlantic oceans about 3 Ma, creating a formidable barrier to dispersal for marine species. However, similar to Simpson's proposal that terrestrial species can 'win sweepstakes routes'-whereby highly improbable dispersal events result in colonization across geographical barriers-marine species may also breach land ...
متن کاملEtiology of thyroid cancer (C73) in Central and South America
Although the etiology of thyroid cancer remains unknown and the reasons for the worldwide increase in its incidence are not well understood, exposure to ionizing radiation in childhood [1] and a medical history of goitre or thyroid nodules have been consistently associated with an increased risk. The most common explanation for the marked increase in incidence over time has been the growing use...
