Halide mineral

Halide minerals are those minerals with a dominant halide anion (F⁻, Cl⁻, Br⁻ and I⁻). Complex halide minerals may also have polyatomic anions.^[1]

Examples include the following:^[2]^[3]

Atacamite Cu₂Cl(OH)₃
Avogadrite (K,Cs)BF
Bararite (β)(NH₄)₂SiF₆^[4]
Bischofite MgCl₂·6H₂O
Brüggenite Ca(IO₃)₂(H₂O)
Calomel HgCl
Carnallite KMgCl₃·6H₂O
Carnallite KMgCl·6H₂O
Cerargyrite/Horn silver AgCl
Chlorargyrite AgCl, bromargyrite AgBr, and iodargyrite AgI
Cryolite Na₃AlF₆
Cryptohalite (a)(NH₄)₂SiF₆^[5]
Dietzeite Ca₂(IO₃)₂CrO₄
Eglestonite Hg₄OCl₂
Embolite AgCl+AgBr
Eriochalcite CuCl₂·2H₂O
Fluorite CaF₂
Halite NaCl
Lautarite Ca(IO₃)₂
Marshite CuI
Miersite AgI
Nantokite CuCl
Sal Ammoniac NH₄Cl
Sylvite KCl
Terlinguaite Hg₂OCl
Tolbachite CuCl₂
Villiaumite NaF
Yttrocerite (Ca,Y,Ce)F₂
Yttrofluorite (Ca,Y)F₂
Zavaritskite (BiO)F

Many of these minerals are water-soluble and are often found in arid areas in crusts and other deposits as are various borates, nitrates, iodates, bromates and the like. Others, such as the fluorite group, are not water-soluble. As a collective whole, simple halide minerals (containing fluorine through iodine, alkali metals, alkaline Earth metals, in addition to other metals/cations) occur abundantly at the surface of the Earth in a variety of geologic settings. More complex minerals as shown below are also found.^[6]
