It is characterized by a strong southward-dipping schistosity and is bounded on both sides by southward-dipping faults, which Sutherland-Brown and Robinson (1971) suggest are en-echelon in character.
One of the prime characteristics of schist is its schistosity, or its micaceous cleavage which means that it readily breaks into sheets.
A structural-textural analysis showed that schistosity developed in the tectonized areas of the Luchlompolo fault as well as blastomylonite and blastocataclasite from tectonic sutures possess a clear and uniform mineral orientation.
