Quin tipus i subtipus de roca i\/o mineral \u00e9s?<\/strong>
\nLa rodonita \u00e9s un mineral de la classe dels silicats, del subgrup inosilicats, i dins d\u2019aquests, pertany als pirox\u00e8s.
\nSilicats: minerals que formen la classe m\u00e9s gran i m\u00e9s important dels minerals (constitueixen aproximadament el 90% de l\u2019escor\u00e7a terrestre). TOTS els minerals silicats contenen oxigen i silici (element qu\u00edmic no met\u00e0l\u00b7lic). Inosilicats: Els inosilicats o silicats en cadena tenen cadenes que poden ser de dos elements qu\u00edmics (SiO3 o Si4O11).
\nPirox\u00e8s: Els pirox\u00e8s s\u00f3n un grup de minerals silicats que es torben en moltes roques \u00edgnies i metam\u00f2rfiques. La seva estructura s\u00f3n cadenes simples de tetraedres de s\u00edlice.<\/p>\n

Formaci\u00f3 de la roca i\/o mineral<\/strong>
\nLa rodonita apareix com un producte primari d\u2019alteraci\u00f3 en dep\u00f2sits hidrotermals i de metamorfisme de contacte (bustamita). Es presenta en gneis, pissarres i roques sediment\u00e0ries.
\nApareix associada a altres minerals en diversos jaciments de magnesi. Es forma sobretot en un tipus de roques anomenades skarn.<\/p>\n

Breu descripci\u00f3 (color, textura.)<\/strong>
\nLa rodonita \u00e9s un mineral d\u2019un color rosat m\u00e9s o menys intens. T\u00e9 una textura cristal\u00b7lina i la seva llu\u00efssor \u00e9s v\u00edtria (semblant al vidre), i \u00e9s transl\u00facid. Quan ratlles el mineral el color de la ratlla que deixa \u00e9s blanc. \u00c9s un mineral bastant dur (de 5,5-6,5 en l\u2019escala de Mhos), encara que una mica fr\u00e0gil. Les seves fractures s\u00f3n desiguals.<\/p>\n

Usos i\/o aplicacions<\/strong>
\nEl seu principal \u00fas \u00e9s com a pedra ornamental (\u00e9s una de les gemmes m\u00e9s conegudes), encara que
\ntamb\u00e9 serveix per: meditaci\u00f3, col\u00b7lecci\u00f3, decoraci\u00f3.<\/p>\n

Lloc d’origen (jaciments m\u00e9s importants)<\/strong>
\nEls jaciments m\u00e9s importants es troben a:
\n\u2022 Muntanyes Urals (R\u00fassia)
\n\u2022 Austr\u00e0lia
\n\u2022 Su\u00e8cia
\n\u2022 Brasil
\n\u2022 Estats Units
\n\u2022 Espanya
\n\u2022 Jap\u00f3
\n\u2022 M\u00e8xic
\n\u2022 Finl\u00e0ndia
\n\u2022 Madagascar<\/p>\n

Significat espiritual<\/strong><\/p>\n

Es diu que la rodonita ajuda a perdonar, facilitant aix\u00ed les reconciliacions entre les persones que constantment s\u2019estan fent mal. Permet la curaci\u00f3 de ferides velles, alliberant-nos del dolor de l\u2019\u00e0nima aix\u00ed com tamb\u00e9 el de la ira continguda, i d\u2019un enuig massa llarg. Tamb\u00e9 es diu que ens ajuda a mantenir-nos conscients i serens ens situacions extremes, ens ajuda a ser prudents i sensats en situacions de provocaci\u00f3 o insults.<\/p>\n
