Short Communication on "Updated geological map of the Borborema Province, northeastern Brazil"

“…The internal compartmentalization of the BP was also revised, based on the integrated geophysical maps (Oliveira and Santos 2020;Correa et al 2020aCorrea et al , 2020b, which allowed the western boundary of the Transverse Zone Domain and the scope of its subdomains to be reassessed (further discussion in Santos et al 2023). This is the first geological map that contemplates the Borborema Province as a whole, therefore it is an unprecedented product, complete, easy to read, presented in the printing scale of 1:1.000.000, but with vector files compatible with the 1:500.000 scale.…”

Gamma-ray spectrometry, magnetic and gravity signatures of Archean nuclei of the Borborema Province, Northeastern Brazil

“…U-Pb on zircon ages obtained from orthogneisses of this complex range from 3.35 to 2.59 Ga (Silva et al 1997;Freimann 2014;Ancelmi 2016;Pitarello et al 2019;Vale et al 2023). Continuity between the two units beneath the Araripe Basin sedimentary rocks has been attributed to the common tectonic control exerted by a NE-SW splay of the E-W shear zones of the Patos Lineament (Santos et al 2023).…”

“…In addition, it was observed that the eTh content is depleted compared to the eU content in most Neoproterozoic metasedimentary units of the Borborema Province (e.g., Cavalcante et al 2016;Uchôa Filho et al 2019;Gomes et al 2021;Costa et al 2023). However, the eTh content is enriched in the Paleoproterozoic gneissmigmatite complexes that compose the basement of the metasedimentary units, for instance, in the Alto Moxotó terrane (Lira Santos et al 2023) and the Rio Piranhas-Seridó domain (Costa et al 2023).…”

Editorial: message from the Editor-in-Chief

“…Oliveira et al (2023) integrate geology and geophysics to investigate the deep structure of the Sergipe Belt. In-depth reviews on lithostratigraphy are presented for the North (Pinéo et al 2023) and Transversal Zone (Santos et al 2023) domains and also for the Mesozoic basins that cover the province (Morais et al 2023). Also introduced in this issue is a new type of publication, the Historical Review, which consists of texts that do not qualify as a scientific review, but contain in-depth reviews of reports and compilations of historical materials worthy of publication.…”
