The chemical formula of mineral Demesmaekerite is indicated by Pb2Cu5(UO2)2(SeO3)6(OH)6•2(H2O). It is commonly found occurring from the lower part of the oxidation zone. Mineral Demesmaekerite is also found from its type of locality at Musonoi mine, Kolwezi, Shaba, Zaire. This mineral was named for Gaston Demesmaeker (1911-), Belgian mining geologist, who studied the Shikolobwe uranium deposits. Demesmaekerite is known to crystallize in the triclinic system of crystal formation. In optical mineralogy, this triclinic crystal system commonly comprises crystals having three axes, of which all are unequal in length and are positioned oblique to one another. Mineral Demesmaekerite has no cleavage displayed when evaluated closely with the aid of polarizing microscope. Demesmaekerite is also found colored brown, brownish green, green or bottle green in hand sample. The density measure of mineral Demesmaekerite is usually found 5.28 grams per cubic centimeters. The crystal habit of mineral Demesmaekerite as described in the field of optical mineralogy usually includes aggregates in form. This is made of numerous individual crystals or clusters that are more interesting when evaluated with the aid of polarized microscope. The hardness measure of mineral Demesmaekerite is usually found ranging from 3 to 4 when evaluated using the Mohs scale method. Demesmaekerite is also found with biaxial positive figure and 0.0750 birefringence when specimen is evaluated using the Mohs scale method. Demesmaekerite is also found showing very strong radioactivity after chemical evaluation.
