Boleite was initial found out in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is becoming well-known for rare minerals. Boleite is such an unconventional and sophisticated mineral the definition of its chemical composition and crystal structure have been through many revisions considering that its initial discovery.
The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. Yet another rare halide mineral within the similar area, with a similar composition and a rather distinctive chemical composition, was named cumengite in honor of Cumenge.
There are several capabilities of boleite that 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 forty nine% lead, fourteen% copper Δαχτυλιδια skroutz and 9% silver. Next, it has a captivating crystal construction, since boleite is often pseudocubically twinned. Which is, Each individual cube-like crystal of boleite is Δαχτυλιδια ΜονοπετÏα definitely composed of a few rectangular box-like crystals oriented at proper angles ΛευκόχÏυσα to each other. Boleite also has an exceedingly eye-catching indigo color and ΧειÏοποίητα Δαχτυλίδια many extremely exceptional transparent crystals are Lower as gemstones.

Like other halide minerals, such as fluorite, boleite is fairly soft, by using a Mohs hardness ranking of only 3 to three.5. It's a vitreous to pearly luster. It is actually an unusually dense mineral, with a particular gravity of five.05. Only a few minerals, for example hematite and cassiterite, have a higher density. Boleite's refractive index can be pretty large at two.03-2.05; increased than sapphire, sphene and demantoid garnet.
In addition to cumengite, There are a variety of other minerals affiliated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite is located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in The usa; and in the Mendip Hills of Somerset, England.
