ZIRC\u00d3N (Zircon)<\/strong><\/h1><\/div>
<\/div><\/div><\/div><\/div>

Sistema cristalino Tetragonal (rombo\u00e9drico)
\nGravedad espec\u00edf. 4,6 – 4,86
\nAlto relieve<\/strong> (n=1,96 – 1,92).
\nH\u00e1bito euhedral, prism\u00e1tico, con terminaciones bipiramidales.<\/strong> Prismas elongados o bajos y anchos. Son raras las caras basales y las maclas. Pueden observarse granos bien redondeados.<\/strong>
\nClivaje imperfecto paralelo a (110) y escaso a pobre seg\u00fan (111). Es com\u00fan el redondeamiento, a\u00fan en granos fracturados. Fractura concoidal.
\nBrillo: v\u00edtreo a adamantino.
\nColor: incoloro, rosa, casta\u00f1o, lavanda, amarillento, verde.
\nDiafanidad: transl\u00facido a translucente.
\nEs com\u00fan la presencia de inclusiones alineadas o dispersas, suelen ser fluidas, gaseosas, de cristales negativos y de minerales como apatita, monacita, rutilo, etc.<\/strong> Puede haber inclusiones dentro de inclusiones. Si son abundantes le dan aspecto sucio al cristal. Pleocro\u00edsmo muy d\u00e9bil. Fuerte en variedades muy coloreadas. Extinci\u00f3n recta. Birrefringencia muy alta. <\/strong>Uni\u00e1xico positivo.
\nMaterial detr\u00edtico proveniente de rocas \u00edgneas (\u00e1cidas a intermedias) m\u00e1s frecuente de granitos, granodioritas y sienitas.
\nTambi\u00e9n, aunque en menor medida de calizas cristalinas, gneises y esquistos.<\/p>\n<\/div><\/div><\/div>
