We present a new approach to the joint inversion of surface wave dispersion data and receiver functions by utilizing Common Conversion Point (CCP) stacking to reconcile the different sampling domains of the two datasets. Utilizing CCP stacking allows us to suppress noise in the data by waveform stacking, and correct for backazimuthal variations and complex crustal structure by mapping receiver functions...
Bouguer gravity data along the Nazca profile of Fukao et al. (1989), NE-SW striking across the Peruvian Andes, are used to investigate the flexure of the Brazilian Shield. Modeling of the observed gravity data indicates that the Brazilian Shield lithosphere is flexed downward and may extend beneath the Andes as far as 150 km. Assuming that the Brazilian Shield behaves elastically, flexural analysis...
