DOI: 10.1016/j.geoderma.2019.03.040

Abstract: Abstract Rare earth elements (REEs) are a group of elements (from La to Lu) with high economic value and serve mainly as essential raw material for various high-technology items. This study explores mineral weathering and… read more here.

DOI: 10.1016/j.gsf.2020.03.004

Abstract: Abstract We present the first evidence of Archean oceanic crust submitted to Proterozoic high-pressure (HP) metamorphism in the South American Platform. Sm–Nd and Lu–Hf isotopic data combined with U–Pb geochronological data from the Campo Grande… read more here.

DOI: 10.1016/j.jsames.2017.02.004

Abstract: Abstract Two granitoid plutons (Piloezinhos and Curral de Cima) intruded along the Remigio - Pocinhos shear zone, eastern part of the Borborema Province. The Piloezinhos and Curral de Cima granites were dated at 566 ± 3 Ma… read more here.

DOI: 10.1016/j.jsames.2021.103280

Abstract: Abstract The Novo Gosto amphibolites represent the oldest unit of the Caninde domain, a Neoproterozoic sequence located in the NW Sergipano Belt, southern Borborema Province, Brazil. The domain comprises an association of metavolcano-sedimentary rocks, gabbroic… read more here.

DOI: 10.1016/j.precamres.2021.106119

Abstract: Abstract 70–80% of the continental crust was produced during the 4.0–2.0 Ga time span, but the preserved area of Archean/early Paleoproterozoic cratons is smaller than 40%. Part of this deficit can be accounted for by the… read more here.

DOI: 10.5194/se-10-893-2019

Abstract: Abstract. The depth-dependent anisotropic structure of the lithosphere under the Borborema Province in northeast Brazil has been investigated via harmonic stripping of receiver functions developed at 39 stations in the region. This method retrieves the… read more here.
