At the central-western part of the Transversal Zone, between the 37°30’ and 40°15’ meridians, along the states of Paraíba and Pernambuco (small part in Ceará), there are three important occurrences of tectonostratigraphic terranes (inliers) of the pre-Brasiliano basement, branching out Ediacaran supracrustal belts, delimited by shear zones. The Açude Coremas and São José do Caiana terranes are truncated to the north by the Patos Lineament (E-W strike), and are separated from each other by the sinistral Boqueirão dos Coxos shear zone (NE-SW strike). Westward (to the interior of Ceará State), these exposures are quite reduced due to the fanerozoic deposits of the Araripe Basin, making it difficult to stress the western limit and exact dimensions of São José do Caiana. The Icaiçara Terrane, located more west-southwest, is bounded to the south by the Pernambuco lineament, and is located entirely in the state of Pernambuco. These tectonostratigraphic terranes are responsible for the branching out of the Piancó-Alto Brígida system into different belts and are constituted of a complex set of granitic gneisses, micaceous gneisses (paragnaisses), with local events of migmatization, associated to some small occurrences of aluminous calc-silicatic and minor amphibolitic supracrustals rocks, Paleoproterozoic in ages. These inliers are predominantly Paleoproterozoic in age (Riaciana). The structural frame is rather complex, because besides two structural phases (at least) of folding in pre-Brasiliano times, there is the imposition of lateral shear movements, with striking transpression components (through the Brasiliano cycle). There are fractions of these basement rocks encasing the Brasiliano supracrustals, as in the south of the Açude Coremas terrane, as already mentioned. The geochronological data obtained, run by different methods, clearly indicate
