\"Resultado<\/p>\n

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

\u00c9s una roca sediment\u00e0ria detr\u00edtica feta amb sorra.<\/p>\n

Formaci\u00f3 de la roca i\/o mineral<\/strong><\/p>\n

Est\u00e0 formada per grans de sorra, cal\u00e7aris, silicis, furriginosos, guixencs, argilosos i bituminosos.<\/p>\n

Composici\u00f3 qu\u00edmica<\/strong><\/p>\n

La composici\u00f3 qu\u00edmica \u00e9s: alumini (Al), silici (Si), calci (Ca), ferro (Fe) i titani (Ti).<\/p>\n

Breu descripci\u00f3 (color, textura…)<\/strong><\/p>\n

El color pot variar des d’un blanc fins a un negre, per\u00f2 el m\u00e9s cmo\u00fa \u00e9s de color marr\u00f3. T\u00e9 una gran duresa i \u00e9s resistent al foc. Si fregues la roca amb qualsevol objectes, o amb les teves mans, podr\u00e1s veure que despr\u00e9s petites part\u00edcules.<\/p>\n

Usos i\/o aplicacions<\/strong><\/p>\n

S\u2019utilitza en algunes construccions, en elements de casa com per exemple les rajoles, per la paret (\u00fas ornamental), pel terre, i tamb\u00e9 en la cer\u00e0mica.<\/p>\n

 <\/p>\n

Lloc d’origen (Jaciments m\u00e9s importants)<\/strong><\/p>\n

L’origen del gres es troba entre la dinastia Han i la dinastia Shang a l’any 1400 a.C. En el s. XII es va comen\u00e7ar la producci\u00f3 del gres a Alemanya. Fins al segle XIV no es va comen\u00e7ar a difondre en la resta dels pa\u00edsos. Per\u00f2 actualment hi ha gres en tot el m\u00f3n.<\/p>\n
