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]
