Quin tipus i subtipus de roca i\/o mineral \u00e9s?<\/strong><\/p>\n

La fluorita \u00e9s un mineral que pertany al grup dels halurs (3.AB). No pertany a cap subgrup.
\nHalurs: els minerals halurs s\u00f3n una classe de minerals que tenen una ani\u00f3 halur dominant.
\nHalur: un halur \u00e9s qualsevol compost que t\u00e9 la forma anui\u00f2nuica, \u00e9s a dir, carregada, negativament, d\u2019un halogen.
\nAni\u00f2nica: La paraula ani\u00f2nica ve de i\u00f3, que, en f\u00edsica i qu\u00edmica, \u00e9s un \u00e0tom o una mol\u00e8cula que no t\u00e9 una c\u00e0rrega el\u00e8ctrica neutra.
\nHalogen: Els hal\u00f2gens s\u00f3n els elements del grup 17 de la taula peri\u00f2dica.
\nFormaci\u00f3 de la roca i\/o muineral<\/strong>
\nLa fluorita apareix en diferents tipus de jaciments, per\u00f2 principalment en aquells d\u2019origen hidrotermal, estant en contacte amb roques carbonatades. En aquestes s\u2019origina la fluorita, per la consolidaci\u00f3 de fluids magm\u00e0tics despr\u00e9s de la solidificaci\u00f3 de roques com granits.
\nTamb\u00e9 s\u2019origina de forma pegmat\u00edtica, estant associada a la cassiterita, turmalina, apatita i topazi. Pot originar-se tamb\u00e9 a cavitats de roques magm\u00e0tiques amb abundant s\u00edlice i en roques metam\u00f2rfiques. L\u2019\u00faltim cas en el que es pot formar \u00e9s en situacions sediment\u00e0ries de dep\u00f2sits procedents d\u2019aig\u00fces volc\u00e0niques en conques tancades.
\nMuinerals assocuiats: Barita, calcita, quars, cassiterita, apatita.<\/p>\n

\nBreu descripci\u00f3 (color, textura.)<\/strong>
\nLa fluorita \u00e9s un mineral d\u2019un color normalment incolor (pur), per\u00f2 degut a les seves impureses pot presentar-se en tons blancs, verds, grocs, ataronjats, vermellosos o violats. El seu lustre \u00e9s vitri, i \u00e9s transparent. La ratlla que deixa si, per exemple, ratllem una clau o una paret \u00e9s blanca.
\n\u00c9s una pedra tova (4 en l\u2019escala de Mhos).
\nApareix formant cristalls c\u00fabics molt ben formats (t\u00e9 forma de cub), encara que tamb\u00e9 pot apar\u00e8ixer en forma d\u2019octaedre. La seva textura pot ser massiva, compacta o granular, i les seves fractures s\u00f3n desiguals.
\nUsos i\/o aplicacions<\/strong>
\nEl principal us de la fluorita \u00e9s l\u2019extracci\u00f3 d\u2019\u00e0cid fluorh\u00eddric. S\u2019utilitza tamb\u00e9 per a fondre bauxita en la producci\u00f3 d\u2019alumini i per augmentar la flu\u00efdesa d\u2019esc\u00f2ries (en metal\u00b7l\u00fargia) degut a la seva capacitat de liquar-se amb facilitat. Els seus cristalls s\u2019utilitzen en la construcci\u00f3 de lents utilitzades en espectrografia.
\nLloc d’origen (jaciments m\u00e9s importants)<\/strong>
\nEls jaciments m\u00e9s importants es troben a:
\n\u2022 M\u00e8xic (la mina m\u00e9s important del m\u00f3n de fluorita es troba a\u00a0Sant Potos\u00ed)
\n\u2022 Xina
\n\u2022 R\u00fassia
\n\u2022 Estats Units (USA)
\n\u2022 Espanya
