New data on Alpine type fluorite deposits: Case of Lújar mine in Betic Cordillera (SE Spain)
2019
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.
