| Abstract | Na região da Bacia Taubaté foram realizadas treze sondagens magnetotelúricas compreendidas num perfil que cortou transversalmente a bacia em sua parte mais espessa, denominada sub-bacia de Tremembé, e prolongou-se pelas limítrofes Serra do Mar a sudeste e Serra da Mantiqueira a noroeste. Os dados foram interpretados através de um modelo de inversão bidimensional e os resultados testados por uma modelagem direta. Uma camada condutora a 10 km de profundidade foi observada claramente sob as regiões cristalinas, mas não foi detectada sob as rochas sedimentares. Tal fato pode estar associado a efeitos de encobrimento resultantes da alta contutância dos sedimentos da bacia. A presença dessa camada condutora na crosta médio-inferior parece ser uma característica global, sendo detectada sob as mais diferentes estruturas geológicas. Aqui, porem, apresentou uma condutância anomalamente baixa para uma região retrabalhada no Neo-Proterozóico. Este aspecto deve ser considerado na formulação de qualquer modelo de evolução tectônica da área. ABSTRACT: Thirteen magnetotelluric soundings were carried out in the Taubaté basin region. They were positioned along a profile cutting across the thickest part of the basin, named Tremembé sub-basin, and extending over the Serra do Mar and Serra da Mantiqueira, respectively to the southeast and northwest. The data were interpreted through a 2-D inversion scheme and the results were tested through a forward modelling. A 10 kin deep conductive layer was observed quite clearly under the crystalline regions but was undetected under the sedimentary rocks. The latter can be probably associated with screening effects due to the high conductance of the surficial sediments. Studies at different tectonic regions in the world have reported the same conductive layer at around the same depth but in the present study the layer has an anomalously low conductance considering that it is a region which was reworked during the Neo-Proterozoic. These findings are strong constraints to any tectonic model suggested to explain regional features. |
