CORNAGLIA, LauraL.; RUIZ, Francisco e INTROCASO, Antonio. Crustal analysis of the San Jorge Basin basedon Bouguer anomalies and geoid undulations. Rev. Asoc. Geol. Argent. [online]. 2009, vol.65, n.3, pp.504-515. ISSN 0004-4822.
Toevaluate crustal characteristics such as crust type and isostatic balance ofthe sedimentary San Jorge Gulf Basin, we analyzed observed Bouguer anomaliesand geoid undulations calculated from free-air anomalies and equivalentsources, comparing them with the responses of a hydrostatic compensated basinmodel prepared using the topographic mass of the area and the basin sedimentaryfill. In both cases we found an excess mass that we explained as a significantcrustal anti-root that predicts subsidence in the future. Others alternativesas for example the emplacement of dense intracrustal masses, do not modifiedthe conclusions.
