Trace element analysis of detrital rutile of the Tacaratu Formation, Tucano–Jatobá Basin. Histograms show the calculated temperatures (Zr-in-rutile thermometry) at 1.0 GPa for metapelitic (i.e. felsic) and metamafic (i.e. mafic) detrital rutile. Left and right pie charts indicate, respectively, the percentage of metapelitic and metamafic detrital rutile grains and the percentage of detrital rutile grains in different metamorphic facies (greenschist/blueschist, amphibolite/eclogite and granulite).

Schematic map from the NE region of Brazil, highlighting the Parnaíba, Araripe and Tucano-Jatobá basins. Light yellow indicates Palaeozoic units interpreted as correlatives of Ipu Formation, including Cariri (Araripe Basin) and Tacaratu formations (Tucano and Jatobá basins). Modified from Assine (1994) and Fambrini et al. (2013).

(a) Borborema Province schematic geological map and main geological features. The Early Paleozoic units represent the Tacaratu Formation of the Tucano–Jatobá Basin and other coeval units (Ipu and Cariri formations). (b) Simplified geological map of the Sergipano Belt, southern Borborema Province, also highlighting the Mesozoic Tucano–Jatobá Basin and the detrital rutile sample locations. X–Y is the approximate location of the geological cross-section of Figure 6.

(a) Kernel density estimate plots (KDEs) for the detrital rutile (this study) and detrital zircon U–Pb ages obtained of the Tacaratu Formation. KDEs are reported for ages without common-Pb correction, 207Pb-based common-Pb correction and 208Pb-based common-Pb correction. It should be noted that the youngest peaks of the detrital rutile are systematically c. 100 myr older than the youngest peak of the detrital zircon at c. 545 Ma. (b) Pie charts showing the age population distribution of detrital rutile (this study) and detrital zircon ages. Cryogenian and Tonian grains are much more represented in the detrital rutile data.
