The chemical composition of mineral Carbokentbrooksite is indicated by the formula (Na,[ ])12(Na,Ce)3Ca6Mn3Zr3Nb(Si25O73)(OH)3(CO3)•H2O. Mineral Carbokentbrooksite is usually found forming from the quartz core of a zoned pegmatite. This mineral Carbokentbrooksite usually found forming at the core of a zoned crystal with zirsilite-(Ce) rim. Eudialyte group. The structure of this mineral was determined. This mineral is most commonly found at its type of locality at Dara-i-Pioz alkaline massif, Tajikistan. Carbokentbrooksite was named for its relationship to kentbrooksite. Mineral Carbokentbrooksite is known to crystallize in the trigonal. Carbokentbrooksite has no cleavage found even when evaluated closely under polarizing microscopes used in the field of optical mineralogy. Mineral Carbokentbrooksite is usually found colored yellow in hand sample. The specific gravity measure of mineral Carbokentbrooksite is usually found 3.14 grams per cubic centimeters. Most crystals of mineral Carbokentbrooksite are found transparent in appearance. Mineral Carbokentbrooksite is usually found showing brittle to conchoidal fracture. This is a very brittle fracture producing small, conchoidal fragments which can be noticed more clearly visible with the aid of polarized microscopes used by mineralogists. Carbokentbrooksite is also commonly found forming rhombohedral crystals and this occurs as well-formed crystals showing rhobohedral crystals. The hardness measure of mineral Carbokentbrooksite is usually found 5 when evaluated using the Mohs scale method. Mineral Carbokentbrooksite is also commonly found exhibiting vitreous or glassy luster in reflected light of polarizing microscopes. Mineral Carbokentbrooksite is also commonly found leaving a white streak when rubbed on white porcelain streak plate. Mineral Carbokentbrooksite is also commonly found with uniaxial negative figure when evaluated between crossed nicols of polarizing microscopes for mineralogists. Mineral Carbokentbrooksite is also commonly found showing 0.0100 birefringence. Carbokentbrooksite has mild radioactivity found after evaluation.
