\nFormaci\u00f3 de la roca i\/o mineral:<\/strong>
\nLa hematita pot apar\u00e8ixer associat a qualsevol tipus gen\u00e8tic de roques. En sediments de mitjans oxigenats i c\u00e0lids associat a algunes sorres i argiles continentals, en calc\u00e0ries pisol\u00edtiques carstificades, en antigues zones pantanoses, etc.
\nEn roques volc\u00e0niques i com a producte d’alteraci\u00f3 d’altres roques \u00edgnies. En roques generades per metamorfisme regional i de contacte. Aproximadament es va descobrir al 3150 a.C. en el temps del Antic Egipte.<\/p>\n
\n\u00c9s un mineral compost d’\u00f2xid f\u00e8rric, la f\u00f3rmula \u00e9s Fe2 O3 i constitueix una important mena de ferro ja que en estat pur cont\u00e9 un 65% d’aquest metall. De vegades posseeix traces de titani, alumini, mangan\u00e8s i aigua.<\/p>\n
