Boleite was first identified in Boleo, Mexico in 1891, in the area in the Baja peninsula that is now well-known for rare minerals. Boleite is such an unconventional and complicated mineral the definition of its chemical composition and crystal structure have been through various revisions considering that its very first discovery.
The very first specimens of boleite were learned by Eduoard Cumenge, a French mining engineer. One more uncommon halide mineral within the similar area, with a similar composition and a rather different chemical composition, was named cumengite in honor of Cumenge.
There are several options of boleite which make it of individual fascination to collectors. For one thing, it's got an abnormal chemical composition, being a hydrated guide copper silver chloride hydroxide. It includes significant portions of these metals, with about forty nine% lead, fourteen% copper and 9% silver. Next, it has a captivating crystal construction, since boleite is often ΧειÏοποίητα Δαχτυλίδια pseudocubically twinned. That's, Each individual dice-like crystal of boleite is actually made up of a few rectangular box-like crystals oriented at appropriate angles to each other. Boleite also has an incredibly appealing indigo coloration and a ΑσημÎνια Δαχτυλίδια few pretty unusual clear crystals happen to be Lower as gemstones.

Like other halide minerals, for instance fluorite, boleite is very tender, 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 instance hematite and cassiterite, have a higher density. Boleite's refractive index is likewise extremely significant at 2.03-2.05; bigger than sapphire, sphene and demantoid garnet.
As well as cumengite, There are a selection of other minerals Δαχτυλιδια bulgari affiliated with boleite, which includes pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
In combination with the deposit in Baja, Mexico, boleite is Δαχτυλιδια bulgari located in Damaged Hill in New South Wales, Australia; inside the Mammoth District ΛευκόχÏυσα of Arizona in The usa; and in the Mendip Hills of Somerset, England.
