Boleite was very first identified in Boleo, Mexico in 1891, inside a region of the Baja peninsula that happens to be famous for exceptional minerals. Boleite is these kinds of an abnormal and complex mineral which the definition of its chemical composition and crystal framework have undergone several revisions since its to start with discovery.
The 1st specimens of boleite ended up found by Eduoard Cumenge, a French mining engineer. Yet another rare halide mineral within the similar spot, with an identical composition and a rather various chemical composition, was named cumengite in honor of Cumenge.
There are many options of boleite which make it of specific desire to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about 49% lead, fourteen% copper and nine% silver. Δαχτυλίδια Secondly, it's got an interesting crystal composition, considering that boleite is usually pseudocubically twinned. That's, Each individual cube-like Δαχτυλιδια Γυναικεια crystal of boleite is definitely composed of a few rectangular box-like crystals oriented at proper angles to one another. Boleite also has an extremely attractive indigo shade and some quite rare clear crystals happen to be Slice as gemstones.

Like other halide minerals, like fluorite, boleite is kind of gentle, that has a Mohs hardness rating of only three to three.5. It's a vitreous to pearly luster. It's an unusually Δαχτυλίδια Γυναικεία dense mineral, with a certain gravity of five.05. Just a few minerals, which include hematite and cassiterite, have a greater density. Boleite's refractive index is likewise extremely significant at 2.03-two.05; increased than sapphire, sphene and demantoid garnet.
In addition to cumengite, There are a variety of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, ΧÏυσά Δαχτυλίδια boleite is located in Damaged Hill in New South Wales, Australia; within the Mammoth District of Arizona in The usa; and in the Mendip ΧÏυσά Δαχτυλίδια Hills of Somerset, England.
