Examples

  • In the center of a mass of quartzites that seem lo constitute the upper level of the eruptive grounds of the province, there are found strata of an ore of iron designated as _itabirite_ -- a mixture of oxide of iron and quartz.

  • It is simply titaniferous iron, iserine, pleonaste, ilmenite [Footnote: Or peroxide of iron, with 8 to 23 per cent, of blue oxide of titanium.] and degraded itabirite, the iron and quartz formation so called in the Brazil; and it is the same mineral which

  • At a greater depth the itabirite will be found solid; and the occurrence of these oldest crystalline formations in large layers is a hopeful sign.
