The chemical composition of mineral Calciocatapleiite is indicated by the formula (Ca,[ ])ZrSi3O9•2(H2O). Calciocatapleiite is most commonly found at its type of locality at Burpala massif, northern Baikal area, Siberia, Russia. This mineral was named for the composition and from the Greek for “wholly’ and “full”, because it is always accompanied by a number of rare minerals. Mineral Calciocatapleiite is known to crystallize in the orthorhombic system of crystal formation. In optical mineralogy, this orthorhombic crystal system comprises crystals having three mutually perpendicular axes, of which all are of different lengths.

Mineral Calciocatapleiite is most commonly found colored light yellow, reddish brown or cream in hand sample. The specific gravity measure of mineral Calciocatapleiite is usually found 2.77 grams per cubic centimeters. Most crystals of mineral Calciocatapleiite are found translucent to opaque in appearance. The hardness measure of mineral Calciocatapleiite when the mineral is evaluated using Mohs scale method is usually found ranging from 4.5 to 5. Calciocatapleiite is commonly found exhibiting vitreous to dull luster when evaluated in reflected light of petrographic polarizing microscope used in the field of optical mineralogy. Mineral Calciocatapleiite is most commonly found leaving a white streak when rubbed on white porcelain streak plate. Calciocatapleiite is also most commonly found showing uniaxial positive figure when evaluated between crossed nicols of petrographic polarizing microscope used in the field of optical mineralogy. It is also commonly found exhibiting 0.0360 birefringence. Calciocatapleiite is a non-radioactive mineral as evaluated.
