SUMMARY Demarcating the continental–oceanic boundary (COB) is extremely important as it contributes to an understanding of the tectonic environments of marginal basins through plate reconstructions. In general, the COB is estimated by jointly inter

Publikováno v: Journal of South American Earth Sciences. 92:1-11

Magnetotelluric (MT) data from 49 broadband and 23 long period stations, covering periods between 10−3 and 104 s, were measured along a NNW-SSE profile of approximately 470 km, crossing the Parnaiba Basin, Borborema Province and Sao Francisco Crato

The intraplate Parana Basin encompasses an area of 1,127,400 km2 in the Brazilian territory and is characterized by the presence of thick basalt and intrusive units of the Serra Geral Formation. Around 70% of its surface is covered by flood basalts.

Marine electromagnetic forward modeling in a resistivity model constrained by seismic and well log data from a field at Campos basin SE-Brazil

Autor: Artur Benevides, Williams Lima, Emanuele F. La Terra, Gary D. Egbert, Naser Meqbel, Paulo Werdt, Sergio L. Fontes

This work presents electromagnetic (EM) responses using both marine magnetotelluric (MMT) and controlled source electromagnetic (MCSEM) methods applied to a resistivity model typical of the Campos basin. The Campos basin is located in the Brazilian e

Electrical crustal structure of Alta Floresta Gold Province eastern sector, SW Amazon Craton, Brazil

Autor: Emanuele F. La Terra, Ved P. Maurya, Clarisse Monteiro Fernandes, Sergio L. Fontes, Leonardo G. Miquelutti

Publikováno v: Journal of South American Earth Sciences. 86:244-258

In this paper we present the results of an investigation on the electric crustal structures depicted by a magnetotelluric (MT) transect cutting through the easternmost sector of the Alta Floresta Gold Province, in the SW Amazon Craton, Brazil. The MT

Crustal framework of the Ribeira and Brasília belts (SE Brazil) inferred from 3D magnetotelluric imaging

Autor: Emanuele F. La Terra, Liliane P. Panetto, Sergio L. Fontes, Miguel Tupinambá

Publikováno v: Journal of South American Earth Sciences. 86:342-352

The interaction between the Sao Francisco Craton and its surrounding belts during the Gondwana formation produced an intricated structural framework with superposition of tectonic events. This work aims to infer the subsurface geoelectric structures

The pre-Silurian Riachão basin: a new perspective on the basement of the Parnaíba basin, NE Brazil

Autor: Amanda Porto, Emanuele F. La Terra, M. C. Daly, Sergio L. Fontes

Publikováno v: Geological Society, London, Special Publications. 472:127-145

We present a new interpretation of the basement immediately below the pre-Silurian unconformity in the mid-western part of the Parnaíba cratonic basin. Regional seismic reflection data, constrained by well and gravity data, have revealed the remnant
