1- NOM<\/strong><\/h6>\n

Catal\u00e0: Guix en punta de fletxa
\nCastell\u00e0: Yeso en punta de flecha
\nAngl\u00e8s: Gypsum<\/p>\n

3- DESCRIPCI\u00d3<\/strong>
\nEs una roca sedimentaria, tamb\u00e9 poden formar roques sedimentaries monominerals. La formaci\u00f3 comen\u00e7a amb el desgast d\u2019altres roques. Els productes del desgast s\u00f3n transportats per l’aigua corrent. En molts casos, els clastos (fragments de roca i gran de minerals s\u2019agrupen per tamanys durant el transport, quan finalment es depositen per
\nformar la roca sediment\u00e0ria, d\u2019aquestes roques es derivar\u00e0 el guix (el procediment \u00e9s massa complicat). Tamb\u00e9 es forma amb l\u2019evaporaci\u00f3 d’aig\u00fces molt salades (salines). Est\u00e0 compost de sulfat de calci hidratat.<\/p>\n

4- OBSERVACI\u00d3 AMB LUPA:<\/strong><\/h6>\n

Es pot observar que estan fetes amb l\u00e0mines, per\u00f2 no \u00e9s una forma perfecta, est\u00e0 molt bruta, es veu brillant
\nper\u00f2 \u00e9s blanca i opaca nom\u00e9s en algunes parts.<\/p>\n

5- \u00daS:<\/strong><\/h6>\n

El guix triturat s’utilitza per millorar les terres agr\u00edcoles,la seva composici\u00f3 qu\u00edmica, rica en sofre i calci, fa que el guix sigui un element de valor com a fertilitzant de la terra, el mineral polvoritzat \u00e9s reparteix perqu\u00e8 els seus components es puguin dispersar en el terreny. L\u2019alabastre \u00e9s el gra que s\u2019obt\u00e9 del guix i s\u2019utilitza per construir.<\/p>\n

6- LLOC D\u2019ORIGEN:<\/strong><\/h6>\n

La Cova dels Cristalls de Naica es troba a 300 metres sota terra. Poblada d’espectaculars i enormes cristalls de
\nselenita o “pedra de la lluna”, ens mostra la seva gran bellesa, en un ambient on l’aparen\u00e7a de gel contrasta -en la profunditat- amb altes temperatures. Naica, apareix davant nostre nom\u00e9s per un instant en la seva llarga
\nvida geol\u00f2gica. Naica forma part de l\u2019estat de Chihuahua \u00e9s un dels 31 estats de M\u00e8xic ,Chihuahua \u00e9s
\nconegut per la seva producci\u00f3 de pomes, nous, fusta, bestiar, productes lactis, ovelles i l\u2019extracci\u00f3 de metalls no f\u00e8rrics. Uns del estils tur\u00edstics m\u00e9s importats de l\u2019estat \u00e9s la barraca del cobre, similar al Gran Cany\u00f3 nord-americ\u00e0.<\/p>\n

8- La PROCED\u00c8NCIA de la pe\u00e7a:<\/strong><\/h6>\n

Prov\u00e9 de l\u2019Escola Dovella i est\u00e0 catalogat per l\u2019Escola Superior d\u2019Agricultura, la directora ha trobat les pedres en unes caixes que estaven en el magatzem de l\u2019aula de tecnologia.<\/p>\n
