Boleite was initial learned in Boleo, Mexico in 1891, in a very area on the Baja peninsula that is now well-known for rare minerals. Boleite is such an unconventional and complicated mineral that the definition of its chemical composition and crystal composition have gone through many revisions given that its initial discovery.
The first specimens of boleite were being learned by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral from the similar area, with a similar composition and a rather different chemical composition, was named cumengite in honor of Cumenge.
There are several capabilities of boleite that make it of particular fascination to collectors. For something, it's got an abnormal chemical composition, becoming a hydrated guide copper silver chloride hydroxide. It includes sizeable quantities of such metals, with about 49% lead, fourteen% copper and nine% silver. Secondly, it's got an interesting crystal composition, considering ΧÏυσά Δαχτυλίδια that boleite is always pseudocubically twinned. That is definitely, Every cube-like crystal of boleite is really made up of 3 rectangular box-like crystals oriented at right angles to one another. Boleite also has an extremely attractive indigo shade and some quite uncommon clear crystals happen to be Slice as gemstones.

Like other halide minerals, including fluorite, boleite is sort of comfortable, with a Mohs ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια hardness score of only three to 3.five. It has a vitreous to pearly luster. It can be an unusually dense mineral, with a specific gravity of five.05. Only some minerals, including hematite and cassiterite, have the next Δαχτυλιδια skroutz density. Boleite's refractive index is additionally pretty substantial at two.03-two.05; increased than ΑσημÎνια Δαχτυλίδια sapphire, sphene and demantoid garnet.
In addition to cumengite, There are a variety ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια of other minerals associated with boleite, like pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In addition to the deposit in Baja, Mexico, boleite has become located in Broken Hill in New South Wales, Australia; inside the Mammoth District of Arizona in America; and within the Mendip Hills of Somerset, England.
