“…Our data combined with previous studies (e.g. Amaral-Santos et al, 2019;Cogné et al, 2011;Hueck et al, 2019;Japsen et al, 2012;Jelinek et al, 2014;Krob et al, 2019;Oliveira et al, 2016;Machado et al, 2019;Van Ranst et al, 2020a) show a widespread erosional denudation during the Late Cretaceous to Paleocene that is strongly imprinted in some of the segments of the Brazilian Atlantic margin, such as the Borborema Province (e.g. Morais Neto et al, 2009) and Mantiqueira Province (e.g.…”

“…Low-temperature thermochronology has only seldomly been applied to basement rocks in the Brazilian interior, in particular not adjacent to our study area, thus the majority of our AFT data covers unexplored locality. Our new AFT data can be compared to a limited number of published AFT results (Amaral-Santos et al, 2019;Carmo, 2005;Doranti-Tiritan et al, 2014;Fonseca et al, 2020;Gallagher et al, 1994;Hackspacher et al, 2004;Jelinek et al, 2014;Martins-Ferreira et al, 2020;Van Ranst et al, 2020a) A clear distinction with respect to the tectonic province can readily be observed in the AFT data set presented here. In general, all AFT central ages range between 386 ± 31 Ma (sample 9) and 59 ± 4 Ma (Sample C11).…”

Differential Phanerozoic evolution of cratonic and non-cratonic lithosphere from a thermochronological perspective: São Francisco Craton and marginal orogens (Brazil)

The São Francisco Craton (SFC) and its marginal Araçuaí and Brasília orogens exhibit a significant diversity in their lithospheric architecture. These orogens were shaped during the Neoproterozoic-Cambrian amalgamation of West Gondwana. The rigid cratonic lithosphere of the SFC and the relatively weak lithosphere of the Araçuaí Orogen were disrupted during the Cretaceous opening of the South Atlantic Ocean, whereas the Brasília Orogen remained in the continental hinterland. In earlier research, the thermal effects of the Phanerozoic reactivations in the shallow crust of the Araçuaí Orogen have been revealed by low-temperature thermochronology, mainly by apatite fission track (AFT) analysis. However, analyses from the continental interior are scarce. Here we present new AFT data from forty-three samples from the Brasília Orogen, the SFC and the Araçuaí Orogen, far from the passive margin of the Atlantic coast (~150 to 800 km). Three main periods of basement exhumation were identified: (i) Paleozoic, recorded both by samples from the SFC and Brasília Orogen; (ii) Early Cretaceous to Cenomanian, recorded by samples from the Araçuaí Orogen; and (iii) Late Cretaceous to Paleocene, inferred in samples from all domains. We compare the differential exhumation pattern of the different geotectonic provinces with their lithospheric strengths. We suggest that the SFC likely concentrated the Meso-Cenozoic reactivations in narrow weak zones while the Araçuaí Orogen displayed a far-reaching Meso-Cenozoic deformation. The Brasília Orogen seems to be an example of a stronger orogenic lithosphere, inhibiting reworking, confirmed by our new AFT data. Understanding the role of the lithosphere rigidity may be decisive to comprehend the processes of differential denudation and the tectonic-morphological evolution over Phanerozoic events.

“…Larger amounts of AFT (and other low-T thermochronological) data are available on the conjugate Brazilian passive margin, such as from the Araçuaí counterpart of the WCB (Fig. 3; Amaral-Santos et al, 2019;Fonseca et al, 2021;Jelinek et al, 2014;Van Ranst et al, 2020b). Before Gondwana breakup, the south-eastern Brazilian highlands, which are underlain by the litho-tectonic units of the Araçuaí Orogen, were directly juxtaposed to the Lower Congo region (Fig.…”
