The Atacama Desert has large quantities of halide minerals as well as chlorates, iodates, oxyhalides, nitrates, borates and other water-soluble minerals. Not only do those minerals occur in subsurface geologic deposits, they also form crusts on the Earth's surface due to the low rainfall (the Atacama is the world's driest desert as well as one ...
The common halide anions are fluoride (F −), chloride (Cl −), bromide (Br −), and iodide (I −). Such ions are present in many ionic halide salts. Halide minerals contain halides. All these halide anions are colorless. Halides also form covalent bonds, examples being colorless TiF 4, colorless TiCl 4, orange TiBr 4, and brown TiI 4.
The Halide Class includes minerals with a halogen as the major anion: fluorine F ...
It belongs to the halide minerals. It crystallizes in isometric cubic habit , although octahedral and more complex isometric forms are not uncommon. The Mohs scale of mineral hardness , based on scratch hardness comparison , defines value 4 as fluorite.

Belloite is a Halide mineral first discovered in the Rio Tinto Mine in Sierra Gorda, Antofagasta, Chile in 1998. [1] Belloite has the ideal chemical formula of Cu(O H)Cl.The mineral has been approved by the Commission on New Minerals and Mineral Names, IMA, to be named belloite, after Andrés de Jesús María y José Bello López, the founder of the Universidad de Chile.
Marshite (CuI) is a naturally occurring isometric halide mineral with occasional silver (Ag) substitution for copper (Cu). [6] [7] Solid solution between the silver end-member miersite and the copper end-member marshite has been found in these minerals from deposits in Broken Hill, Australia. [8]
Those other minerals include terlinguaite Hg 2 OCl, formed by the weathering of mercury-containing minerals. [23] Mendipite, Pb 3 O 2 Cl 2, formed from an original deposit of lead sulfide in a number of stages is another example of a secondary oxohalide mineral. The elements iron, antimony, bismuth and lanthanum form oxochlorides of general ...
