The research area is situated in the northwestern portion of the Bacajá Domain, southeast of the Amazon Craton. The region comprises rocks with ages ranging from Mesorchean to Paleoproterozoic, originating from continental and oceanic arcs, later amalgamated and reworked by collision with the Carajás block. In this context, important shear zones oriented in the WNW direction have developed. These structures have been delineated from radar and aerogeophysical images, with the delineation and interpretation of the traced lineaments presenting a sigmoidal pattern tending towards sinistral transcurrent kinematics. The rocks studied are protomylonitic monzogranites from the Canaã Granite Unit, and migmatitic gneisses from the Ortogneisse Uruará and Paragneisse Ipiaçava units. The foliation is oriented NW to WNW with moderate to high dip, and the mineral lineations show a slope of around 45° to the NW. This relationship may indicate oblique movement along the shear zones. It is understood that these zones are responsible for guiding the placement of units in the domain, as well as generating significant deformations reflected in the form of cataclastic rocks, and to a greater extent, mylonitic rocks. On a microscale, it is possible to observe structures such as wave extinction and subgrains in quartz crystals, marking the beginning of plastic deformation, later transitioning to dynamic recrystallization with microstructures BLG (Bulging Recrystallisation) → SGR (Subgrain Rotation Recrystallisation) → GBM (Grain Boundary Migration Recrystallisation). Sigma-type porphyroclasts with both sinistral and dextral kinematics are commonly observed in the mylonitic foliation, although sinistral kinematics are more recurrent.
