The Vazante and Canastra groups revisited: Sm-Nd and Sr isotopes - evidence for contribution from Tonian intraplate magmatism during passive margin development along the SW São Francisco margin, Brazil

Brazilian Journal of Geology, 2019
Combined Sm-Nd isotope studies and U-Pb ages of detrital zircons have shown significant differences between the provenance patterns of Neoproterozoic metasedimentary successions in the Southern Brasília belt.

Return to Rodinia? Moderate to high palaeolatitude of the São Francisco/Congo craton at 920 Ma [PDF]

, 2015
Moderate to high palaeolatitudes recorded in mafic dykes, exposed along the coast of Bahia, Brazil, are partly responsible for some interpretations that the São Francisco/Congo craton was separate from the low-latitude Rodinia supercontinent at about ...

Palaeoproterozoic Assembly of the São Francisco craton crust, SE Brazil: New insights from U-Pb titanite and monazite dating

, 2021
Isotopic U-Pb titanite and monazite data from the southern São Francisco craton better constrain the timing of the tectono-thermal event that led to the amalgamation of the craton and the crust that forms the basement of its fringing orogenic belts in ...

Diamictitos e"Cap Dolomites" sturtianos sobre o grupo jacobina - Araras, Norte de Campo Formoso - Bahia

Geologia USP. Série Científica, 2008
A ocorrência de diamictitos - provavelmente glaciais -, sotopostos a calcários no norte de Campo Formoso-BA, adjacências da vila de Araras, já havia sido observado"en passant" por alguns autores nas décadas de 60 e 70, e inclusive chega a fazer parte de ...

Implications for the refinement of the São Francisco Craton magmatic barcode and the North China link.

, 2022
Late Archean to Paleoproterozoic dike swarms crosscut the basement and supracrustal sequences of the São Francisco Craton. Their spatial distribution and orientation patterns, as paleomagnetic signature, provide key evidence to the positioning of the ...

A XENOLITH-BASED LITHOSPHERIC TRANSECT OF THE SLAVE CRATON, N.W.T., CANADA [PDF]

, 2012
During the last decade, the Canadian Slave craton has emerged as an important global diamond resource. Recent work on the sub-continental lithospheric mantle (SCLM) beneath this craton has yielded tantalising suggestions about its structure and ...
