• Fluorite (CaF2) is an essential fluorine ore for modern industry (e.g. metallurgical and chemical). There are two most common styles of mineralization for this mineral (included in the list of Critical Raw Materials for European Union): deposits in sedimentary rocks, mostly carbonates, and deposits related with igneous activity.

  The former is typically associated to Mississippi Valleytype (MVT) deposits, which suggest an epigenetic origin for the ores. However, there are some cases in which the characteristics of this style of mineralization are not totally compatible with the MVT model and are quoted in the literature as Alpine-type deposits until late 1990s.

  Since then, there is little focus on this peculiar ore deposit type.
