The Cariri Velhos belt is a belt of rocks in Brazil that were deformed and metamorphosed in the Early Neoproterozoic.[1] The belt runs from the Atlantic more than 700 km inland in a SWW direction. The width of the belt varies from 100 to 50 km.[2]

Seen in a map the Cariri Velhos belt lies intercalated in mosic with various Brasiliano cycle belts in the Borborema Province, a geologic province in Northeastern Brazil. The belt include a series of orthogneisses, metavolcanic and metasedimentary rocks. It is not known if the plate tectonic events that led to the formation of the belts are related to the assembly of the supercontinent Rodinia.[1]
