文摘

Southern São Francisco craton titanite and monazite resetting between 2080 and 1940 Ma. Syn-collisional metamorphism between 2100 and 2070 Ma. Final closure of the Minas basin in the 2100–2070 Ma interval. Dome-and-keel structure generated by orogenic collapse at ca. 2070–2050 Ma. Slow cooling lasted until ca.1940 Ma.
