Garnet-bearing micaschists are composed of quartz, biotite, muscovite, garnet, plagioclase with accessory and opaque minerals. Structural observations in the Soubré area reveal a first foliation (S1) trending NW-SE, dipping between 40° and 85° towards SW and associated with a N080-trending shear with a sinistral component, as well as folds whose axial planes are parallel to S1. This first foliation is intersected by a second (S2) trending NE-SW with dips of 60-85° either towards NW or SE. The S2 foliation is associated with a N166 shear with a sinistral component and folds whose axial planes are parallel to S2. All these structural observations in the Soubré sector would be compatible with the structures observed in the SASCA domain on the coast from Grand-Béréby to Tabou.

Abstract
The Sassandra-Cavally (SASCA) domain (SW Côte d’Ivoire) marks the transition between the Archean Kenema-Man craton and the Paleoproterozoic Baoulé-Mossi domain. The methodology applied to study the rocks of the Soubré area considers both field and laboratory work. The Soubré area of the SASCA domain is characterized by migmatitic gneisses, metagranites and garnet micaschists. Migmatitic gneisses are composed of quartz, feldspar, biotite, chlorite, muscovite and opaque minerals, with occasional amphibole rods. Metgranites, on the other hand, are composed of quartz, feldspars such as plagioclase and microcline, biotite, accessory minerals and opaque minerals. Garnet-bearing micaschists are composed of quartz, biotite, muscovite, garnet, plagioclase with accessory and opaque minerals. Structural observations in the Soubré area reveal a first foliation (S1) trending NW-SE, dipping between 40° and 85° towards SW and associated with a N080-trending shear with a sinistral component, as well as folds whose axial planes are parallel to S1. This first foliation is intersected by a second (S2) trending NE-SW with dips of 60-85° either towards NW or SE. The S2 foliation is associated with a N166 shear with a sinistral component and folds whose axial planes are parallel to S2. All these structural observations in the Soubré sector would be compatible with the structures observed in the SASCA domain on the coast from Grand-Béréby to Tabou.
