The Andean elevation in Argentina-Chile at 39° south latitude from gravity data

Mostrar todas las versiones(2)

In this paper, we analyze an E-W gravity section at 39° South latitude. It extends from the western Chilean trench, across the Andean belt, into Argentina, and reaches the Atlantic Ocean. The minimum Bouguer anomalies, in the order of-90 mGal, are located in coincidence with the maximum Andean altit...

description In this paper, we analyze an E-W gravity section at 39° South latitude. It extends from the western Chilean trench, across the Andean belt, into Argentina, and reaches the Atlantic Ocean. The minimum Bouguer anomalies, in the order of-90 mGal, are located in coincidence with the maximum Andean altitudes, while the largest values, of about +230 mGal, are located offshore, in the Pacific Ocean. We present simple crustal models, among others considering the possible gravity influence of the subduction system Nazca Plate - Southamerican Plate. Isostatic models that combine the Airy and Pratt's hypothesis are also detailed. Orogenic Shortenings were also calculated by using the topographic areas above the sea level and the crustal root below the assumed "normal" crustal thickness for different models.
