In the study in the municipality of Charity , in the northern state of Ceará , area four distinct lithological types were identified : migmatitic , garnet schist , amphibolite and granitic gneiss gneiss , and the presence of a dike of basalt, quartz pockets . The metassediments passed a compressional regime where the increase of temperature and pressure brought about the fusion of the material , resulting in the formation of paragneisses found, which comprise most of the outcropping rock. The outcrops studied have diving low to medium angle, with preferred direction to NE - SW . The migmatitic gneiss sequences are always associated / intercalated schistose the package and many rock outcrops. The amphibolites are probably restitos that escaped the melting processes due to its refractory character. The basalts represent dike and quartz blocks are associated with the partial melting process.
