Structural interpretation of the northern flatslab zone from magnetic data. Precordillera of San Juan and La Rioja
The Andean region between -28° to -31° of latitude included the transition of geological provinces: Front Range, Western Sierras Pampeanas and Precordillera in the provinces of San Juan and La Rioja. The geological evolution and the compressive tectonic regime in the area could have made its mark in...

| 520 | 3 | |a The Andean region between -28° to -31° of latitude included the transition of geological provinces: Front Range, Western Sierras Pampeanas and Precordillera in the provinces of San Juan and La Rioja. The geological evolution and the compressive tectonic regime in the area could have made its mark in areas where micro-continents collided and amalgamated, identified as suture zones. From a base of magnetic data collected from different types (air and land) sources and acquired at different times, a series of geophysical reductions in order to obtain a single homogeneous database was applied. At the map of Total Magnetic Anomaly obtained, we applied two different methods of filtering: Analytic Upward Continuation and Frequency. Finally, on cross sections toward East - West, solutions from 2D Werner deconvolution - with results consistent with the existing models for Precordillera and it structure - were calculated. We have interpreted the arrangement of units with different magnetic susceptibility correlating these with the configuration of Paleozoic "terranes" amalgamated in this region. The location of Werner solutions allowed us to recognize the behavior in depth of the exposed structures. © 2015 Asociación Argentina de Geofísicos y Geodestas. |l eng | |
