Geologically, the spatial cutout is part of the context of the Tacaratu Sandstone, tectonically inserted in the Jatobá Basin, which according to Rocha (2011) is installed entirely in the Pernambuco –Alagoas Province of Borborema Land and integrates the Recôncavo - Tucano Rift System - Jatobá (Almeida, 1967). There is also the Xingó instructive Suite that composes the basement rocks. |
It allows privileged view of one of the arms of the São Francisco River and of
significant spatial dimension of the sandstone of the Tacaratu Formation bathed by the River.
According to Gúzman et al. (2015), the regional geological framework of the Jatobá Basin cannot be understood without making reference to the geological evolution of the NE of Brazil, and its relationship with the origin of the South Atlantic Ocean. |
the stratigraphy of this Basin was individualized due to the differences in its sedimentary and tectonic-structural record with those of the Recôncavo and Tucano basins. The fundamental differences are found in the broader Paleozoic than in the Recôncavo Basin, and the rift phase, much less pronounced. According to Rocha (2011), the Jatobá Basin is structurally characterized by a gray medium with the substrate predominantly constituted by rotated and progressively lower blocks towards NW.

According to the stratigraphic column of the Basin, modified by Newman et. al. (2009), the deposits of the Tacaratu Formation of Siluri-Devonian age were deposited in an interlaced fluvial environment, associated with alluvial fans, composed lithologically of thick sandstones to conglomerates of gray, pink and red colors with lateritic crusts.Rocha (2011) describes lithologically, the Tacaratu Formation is a predominantly sandy sequence, with grayish-white to reddish-pink sandstones, of medium to conglomeratic granulation, Serra Grande of the Parnaíba Basin, and the Mauriti Formation of the Araripe Basin.
