The chemical formula of mineral Cameronite is indicated by AgCu7Te10. This mineral is most commonly found occuring in hydrothermal deposits in telluride-rich ores. It is also most commonly found at its type f locality at Good Hope mine, Vulcan, Colorado, USA. Mineral Cameronite was named for Eugene N. Cameron (1910-), U.S. Economic geologist. Mineral Cameronite is known to crystallize in the tetragonal system of crystal formation. In optical mineralogy, this tetragonal system comprises crystals having three axes, which are all in a position perpendicular to one another. Two axes are usually found having the same or equal length. Cameronite has no cleavage found even if evaluated closely with the aid of polarizing microscope for mineralogists. Mineral Cameronite is usually found colored black or gray in hand sample. Most crystals of mineral Cameronite aree found opaque in appearance. Mineral Cameronite is commonly showing brittle to conchoidal fracture when evaluated with the aid of polarized microscope used in the ffield of optical mineralogy. This is a very brittle fracture producing small, conchoidal fragments. The crystal habit of mineral Cameronite as described in the field of optical mineralogy usually includes anhedral grains. These are granular minerals without the expression of crystal shapes. It can be also found forming microscopic crystals wherein crystals are visible only when viewed closely with the aid of polarizing microscopes for mineralogists. The hardness measure of mineral Cameronite is usually found ranging from 3.5 to 4 when eevaluated using the Mohs scale method. Mineral Cameronite is also commonly found showing metallic luster when evaluated in reflected light of polarizing microscope. Cameronite is usually found leaving a black streak when viewed closely under polarizing microscope used in the field of optical mineralogy. This mineral is also commonly found showing distinct anisotrophism commonly exhibiting medium gray to slate-gray to brownish gray color. Cameronite is also fund to be slightly pleochroic showing pale gray to pale brownish gray color when viewed between crossed nicols of petrographic polarizing microscopes. Cameronite is also found to be not radioactive.
