Boleite was to start with found in Boleo, Mexico in 1891, inside a location of your Baja peninsula that has grown to be popular for unusual minerals. Boleite is this sort of an uncommon and complex mineral which the definition of its chemical composition and crystal construction have undergone several revisions since its to start with discovery.
The main specimens of boleite ended up found by Eduoard Cumenge, a French mining engineer. Another scarce halide mineral with the identical location, with the same construction and a rather diverse chemical composition, was named cumengite in honor of Cumenge.

Like other halide minerals, including fluorite, boleite is sort of delicate, which has a Mohs hardness rating of only three to 3.five. It's got a vitreous to pearly luster. It is actually an unusually dense mineral, with ΧÏυσά Δαχτυλίδια a certain gravity of 5.05. Just a few minerals, which include hematite and cassiterite, have a better density. Boleite's refractive index is usually really superior at ΛευκόχÏυσα 2.03-two.05; higher than sapphire, sphene and demantoid garnet.
Together with cumengite, There are a selection of other minerals connected with boleite, together with pseudoboleite, chloroxiphite, paralaurionite, matlockite, chlorargyrite, bideauxite, atacamite, mendipite and diaboleite.
As well as the deposit in Baja, ΧÏυσά Mexico, boleite has long been found in Broken Hill in New South Wales, Australia; from the Mammoth District of Arizona in the United States; and ΧÏυσά & ΛευκόχÏυσα Δαχτυλίδια while in the Mendip Hills of Somerset, England.
