We present a new set of contour maps of the seismic structure of South America and the
surrounding ocean basins. These maps include new data, helping to constrain crustal …

The detection of a seismic boundary, the “Moho”, between the outermost shell of the Earth,
the Earth's crust, and the Earth's mantle by A. Mohorovičić was the consequence of …

We forward modeled the Bouguer anomaly in a region encompassing the Pacific Ocean
(85° W) and the Andean margin (60° W) between northern Peru (5° S) and Patagonia (45° …

Abstract The Borborema Province BP (NE Brazil) consists of a complex rock mosaic
composed mainly by Proterozoic metasedimentary belts that amalgamate Archean-to …

We present a crustal thickness map of Brazil and adjacent areas based on a compilation of
data published in the literature as well as new measurements. We used crustal thicknesses …

The application of potential field methods in regional geophysical studies with orbital data
has proven helpful in identifying, modeling, and dimensioning structural features and …

Previous compilation of crustal structure in South America had large unsampled areas
including the thin crust in the Sub‐Andean lowlands, largely estimated by gravity data, and …

A two‐dimensional model of the Brazilian central crust and upper mantle was obtained from
the traveltime interpretation of deep seismic refraction data from the Porangatu and …

Seismologic observations in the last decades have shown that the crustal thickness in
Paraná basin locally is over 40 km thick, which is a greater value than expected by the …

We present a review of seismological constraints on deep crustal structures underlying large
igneous provinces (LIPs), largely from wide‐angle seismic refraction surveys. The main …
