Preliminary study of gravimetric anomalies in the Magallanes-Fagnano fault system, South America
(KeAi Communications Co, 2017-12)
The main objective of this research is to recognize several geological structures associated with the shear zones of the MFFS (Magallanes – Fagnano fault system) by the analysis and interpretation of gravimetric anomalies. ...
Fractalness of land gravity data and residual isostatic anomalies map of Argentina, Chile and western Uruguay
(Universidad Nacional Autónoma de México. Instituto de Geofísica, 2015-04)
Gravity anomalies are often strongly influenced by topography, which effect is mitigated through appropriate reductions. Usually, a standard value of 2670 kg/m3 is used for the density of topography in the absence of ...
Alternative gravimetric methodology for isostatic analyses. An example for Bolivian Andes
(Instituto de Fisiografía y Geología, 2009)
Isostatically disturbed terrain of northwestern andes mountains from spectrally correlated free-air and gravity terrain data
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2006)
Recently revised models on global tectonics describe the convergence of the North Andes, Nazca, Caribbean and South American Plates and their seismicity, volcanism, active faulting and extremetopography. The current plate ...
3D Process-Oriented Gravity Modelling applied north of 49°S on the Argentine continental margin
(Pergamon-Elsevier Science Ltd, 2018-01)
The Process-Oriented Gravity Modelling (POGM) technique represents a useful way to distinguish the contribution that different geological processes make to the observed gravity in passive margins. The POGM is an innovative ...
A plastic rheology phenomenological 201 . model that explains the Andes evolution in northern Argentina
(Instituto de Fisiografía y Geología. Facultad de Ciencias Exactas, Ingeniería y Agrimensura. Universidad Nacional de Rosario, 2012)
Indicadores gravimétricos isostáticos en cuencas sedimentariasIsostatic gravity indicators on sedimentary basins
(Instituto Tecnológico Geológico y Minero de España, 2001-12)
Investigamos las respuestas gravimétricas teóricas de modelos de cuencas sedimentarias suponiendo dos mecanismos de compensación, 1) hidrostático del tipo Airy (lo denominamos “modelo de estiramiento”), y 2) flexural ...
Crustal deformation in the Rio de la Plata estuarine (South Atlantic passive margin) and the associated seismicity as a consequence of an isostatic readjustment
(Elsevier, 2020-11)
The Río de la Plata estuarine has been the epicenter of the 30 November 2018 intra-crustal earthquake with a magnitude and focal depth of 3.7 and 19 km (±6 km), respectively, which alerted the Buenos Aires city population. ...
