context_page_description: Halide minerals are those minerals with a dominant halide anion. Complex halide minerals may also have polyatomic anions.
  Examples include the following:
  Atacamite Cu₂Cl(OH)₃
  Avogadrite BF
  Bararite (NH₄)₂SiF₆
  Bischofite
  Brüggenite Ca(IO₃)₂
  Calomel HgCl
  Carnallite KMgCl₃·6H₂O
  Carnallite KMgCl·6H₂O
  Cerargyrite/Horn silver AgCl
  Chlorargyrite AgCl, bromargyrite AgBr, and iodargyrite AgI
  Cryolite Na₃AlF₆
  Cryptohalite (NH₄)₂SiF₆
  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 F₂
  Yttrofluorite F₂
  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 occur abundantly at the surface of the Earth in a variety of geologic settings. More complex minerals as shown below are also found.

  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.
