Architecture of the intracontinental Jaibaras Rift, Brazil, based on geophysica...
Pedrosa Júnior, Nilo Costa; Vidotti, Roberta M.; Fuck, Reinhardt A.; Castelo Branco, R.M.G.; Almeida, Afonso R. de; Silva, Nilton C. VieiraQualitative and quantitative integration and interpretation of magnetic, gravity and magnetotelluric data help to determine the internal architecture of the Jaibaras rift, and allow assessing the evolution of the Jaibaras Rift within the Precambrian crystalline basement of Borborema Province, NE Brazil. This was achieved by 2D joint modeling of magnetic and gravity data in five sections across the main axis of ...
Two-stage terrane assembly in Western Gondwana: Insights from structural geolog...
Santos, Lauro Cézar M. de Lira; Dantas, Elton L.; Vidotti, Roberta M.; Cawood, Peter A.; Santos, Edilton J. dos; Fuck, Reinhadt A.; Lima, Haroldo M.Combined geophysical and structural data from the Transversal Subprovince of the Borborema Province (NE Brazil) highlight the internal structure of, and interrelationships between, the constituent terranes. Radiometric and magnetic maps show distinctive signatures for the Archean-Paleoproterozoic Alto Moxotó and Meso-to Neoproterozoic Alto Pajeú and Pernambuco-Alagoas terranes. Mapped radiometric and first and ...
Structural framework of the Jaibaras Rift, Brazil, based on geophysical data
Pedrosa Júnior, Nilo Costa; Vidotti, Roberta M.; Fuck, Reinhardt A.; Oliveira, Karen M. Leopoldino; Castelo Branco, R. Mariano G.The Cambro-Ordovician Jaibaras Rift is a NEeSW trending elongated feature, controlled by the Transbrasiliano lineament, locally known as Sobral-Pedro II shear zone (SPIISZ). An integrated study of geophysical data (gammaspectrometry, magnetometry and gravimetry) was undertaken in the Jaibaras Rift area, between Ceara Central (CCD) and M edio Coreaú domains (MCD), northwest Borborema Province. Geophysical data w...
