These basement rocks comprise the Bacaeri-Mogno Complex, formed during a phase of oceanic basin convergence and closure that led to subduction and oblique collision with the remnants of the Cuiú-Cuiú arc. This process occurred under more severe pressure (P) and temperature (T) conditions, resulting locally in the transition from amphibolite to granulite facies.
The studied area is located in the Juruena Domain, consisting of felsic plutonic and volcanic rocks of the Andean arc type, with calc-alkaline composition and high potassium, formed between 1860 and 1820 Ma, where gold deposits are found, which are defined in two types: In the volcanic rocks (rhyolites and rhyodacites), where the mineralization is generally disseminated in the rock. The second ore type is defined as quartz-vein stockwork, generally aligned with larger NE structures. The igneous rocks (granites and monzogranites), in turn, are aligned with a main structural control in the NW direction and, less commonly, in other directions, following the NE strike, and are located in zones of hydrothermal alteration.
