Friable itabirite with levels stronger siliceous.
Locally with specularite. Lenses of schists are founded.
Comments – This interval of friable itabirite with lenses of
schist are located closed of shear zone that is
characterized by quartz and specularite associated a
hydrothermal process. This process and mineralogy
(white mica) of schist are probable responsible for values
of alumina. The chemical formula is
KAL2Si3AlO10(OH,F)2 and the composition is 11.82%
