Boleite was initial learned in Boleo, Mexico in 1891, in a very area in the Baja peninsula that is now well-known for rare minerals. Boleite is these types of an strange and complicated mineral that the definition of its chemical composition and crystal composition have gone through numerous revisions because its first discovery.
The main specimens of boleite have been identified by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral with the exact same location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.
There are numerous attributes of boleite which make it of distinct desire to collectors. For something, it has an strange chemical composition, getting a hydrated lead copper silver chloride hydroxide. It has important quantities of those metals, with about 49% direct, 14% copper and nine% Δαχτυλίδια silver. Secondly, it's a fascinating crystal framework, because boleite is often pseudocubically twinned. Which is, Each individual cube-like 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 have been Slice as gemstones.

Like other halide minerals, like fluorite, boleite ΑσημÎνια Δαχτυλίδια is kind of gentle, that has a Mohs hardness rating of only three to 3.five. It has a vitreous to pearly luster. It truly is an unusually dense mineral, with a specific gravity of 5.05. Only some minerals, like hematite and cassiterite, have an increased density. Boleite's refractive index can also be incredibly higher at two.03-two.05; greater than sapphire, sphene and demantoid garnet.
Besides cumengite, there are a number Δαχτυλιδια skroutz of other minerals linked to boleite, including pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, Mexico, boleite Δαχτυλιδια skroutz has long been found in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona ΑσημÎνια Δαχτυλίδια in the United States; and inside the Mendip Hills of Somerset, England.
