The northwest of Borborema Province is known for the diversity of granites, either chronological or tectonic their natures, elevating the importance of these magmatic events in the regional context, producing high complexity magmatic-metamorphic terrains, representing advanced stages of magmas generation during older deformational processes. The Brazilian Event is important because it has affected the whole Borborema Province with continuity for the African Continent (Pan-African Event). Its evolution related to changing global geotectonic involving collages of continents, oceans lock, orogeny, as well as a succession of magmatic pulses that spread throughout the event, forming large-migmatitic granitic suites, scoring several deformation and injection of magmas episodes. Thus, the geochronological studies seek to understand these magmatic events, their timing and context in the lithologic units formation that compounds the current northwestern Borborema Province framework. The Chaval Granite located in the northwest of the Borborema Province is an example of a pluton that needed a review because there is a discrepancy in the age values, and applications of accurate geochronological methods that was done in this work. It was done a comparative study to other granitic bodies and discussed the significance of the ages and contextualized them in the evolution of the NW Borborema Province. Previous Geochronological studies obtained varied ages (1990 ± 18mA, 591 ± 10 and 507 ± 27 Ma), providing an uncertainty about the actual age of placement Granite Chaval. This work as a TCC aimed to determine the age of Granite Chaval, using accurate techniques and dating methods, such as the Pb-Pb on zircon method. The crystallization age value obtained was 633 ± 3.3 Ma, demonstrating that Chaval Granite crystallization occurred at the end of the Neoproterozoic, and can not be included in Meruoca Intrusive Suite, whose the ages is around 523 Ma, and it is considered a post-tectonic magmatism in relation to Brazilian orogeny. Moreover, older ages, such as the granites of Tamboril Santa Quitéria Complex ranging from 664.8 ± 5.2 Ma to 623.9 ± 1.3 Ma ages, which may be related to Chaval Granite and syn- to late tectonic magmatism in relation to orogeny Brazilian.
