West Gondwana orogenies and Pangaea break-up: Thermotectonic effects on the southernmost Mantiqueira Province, Brazil
JPSL Machado, AR Jelinek, MM Bicca… - Journal of the …, 2019 - lyellcollection.org
Through the joint use of apatite fission tracks (AFT) and (U–Th)/He analysis in apatite (AHe)
and zircon (ZHe), we evaluate the thermotectonic evolution of the Sul-Rio-Grandense Shield
(SRGS), southernmost Mantiqueira Province, Brazil. Formed during the assembly of West
Gondwana (Neoproterozoic), the shield comprises four tectonostratigraphic terranes
separated by regional faults and shear zones. The central and eastern terranes present
Mesozoic AFT ages, whereas the western terrane ages are mostly late Paleozoic. AHe ages …
