The chemical formula of mineral Aluminotaramite is indicated by Na(CaNa)(Fe+++3Al2)(Si6Al2)O22(OH)2. Aluminotaramite is most commonly found occuring in the Liset kyanite-eclogite pod, a retrogressed eclogite. Aluminotaramite is a very high pressure metamorphic rock. It is also a known member of Amphibole group. Liset, near Selje, Möre og Romsdal County, Vestlandet, Norway. Mineral Aluminotaramite is known to crystallize in the monoclinic system of crystal formation. In optical mineralogy, the monoclinic system of crystal formation comprises crystals having three axes of unequal lengths. Two of which are usually found in a position that is oblique or not perpendicular to one another. However, both of which are commonly found perpendicular to the third axis.

            Aluminotaramite is usually found showing poor cleavage in two directions which can be seenh more clearly exhibited when viewed with the aid of polarizing light microscope used in the field of optical mineralogy. Aluminotaramite is usually found green bluish which is can be seen more ffasinating under polarized microscope for mineralogists. Mineral Aluminotaramite is usually found showing brittle tenacity. In the field of optical mineralogy, this is generally displayed by glasses and most non-metallic minerals as evlauted. The crystal habit of the mineral Aluminotaramite as described in the field of optical mineralogy usually includes microscopic crystals which are only made visible with the aid of polarizing microscopes for mineralogists. Aluminotaramite is most commonly found exhibiting vitreous or glassy luster when viewed in reflected light of petrographic polarizing microscope used in the field of optical mineralogy. Aluminotaramite is known showing bixial negative figure when evaluated between crossed nicols of petrographic polarizig light microscope used in the field of optical mineralogy. It is also most commonly found showing 0.0210 birefringence. Aluminotaramite is also often found showing extreme dispersion. Aluminotaramite has a barely detectable radioactivity as evaluated.
