The chemical formula of mineral Senarmontite is indicated by Sb2O3 or Antimony Oxide. Senarmontite actually belongs to the Oxides and Hydroxides mineral class. Senarmontite is considered as a minor ore of antimony. It is also most commonly used as mineral specimen. When evaluated with the aid of petrographic polarizing light microscope used in the field of optical mineralogy, mineral Senarmontite is usually found showing fascinating images. Senarmontite is said to be an under appreciated mineral and it is rather scarce type and not so widely distributed. Hence, good Senarmontite specimens are hard to find. Senarmontite is also known to be forming excellent octahedral crystals that can be transparent in appearance exhibiting high luster in reflected light of polarized microscopes for mineralogists. Senarmontite specimens with dozens of octahedrons of randomly varying sizes are especially admirable. Senarmontite is said to be dimorphous with mineral Valentinite. In optical mineralogy, dimorphous minerals have exactly the same chemistry but they have different structures. Senarmontite and Valentinite are oxidation products of the antimony sulfide.

 

            Mineral Senarmontite is most commonly found colorless, white or gray in color that could be also interesting when viewed with the id of polarizing microscope used in optical mineralogy. Senarmontite is usually found showing vitreous, adamantine, greasy or resinous luster in reflected light of petrographic polarizing light microscopes for mineralogists. Senarmontite crystals are usually found translucent to transparent in appearance. The crystal habit of mineral Senarmontite as described in the field of optical mineralogy typically includes well formed octahedral crystals but more commonly found massive as well as granular and encrusting. Senarmontite is known to crystallize in the isometric system of crystal formation.

 

            Mineral Senarmontite is most commonly found showing imperfect cleavage when specimen is closely examined under polarized microscopes for mineralogists. It is also commonly found exhibiting conchoidal fracture when viewed under polarizing microscopes used in optical mineralogy. Senarmontite is also most commonly found leaving a white streak when specimen is rubbed on a white porcelain streak plate. The specific gravity measure of the mineral Senarmontite is approximately 5.3 to 5.5 grams per cubic centimeters, which is heavier than average. Senarmontite is usually found associated with other minerals including quartz, Valentinite, stibnite, native antimony, stibiconite and other antimony minerals. The best field indicators of mineral Senarmontite usually include high luster, specific gravity, crystal habit and associations. Senarmontite has limited occurrence at Djebel Haminate Mine in Algeria and it can be also found at Quebec, Canada.
