SCH-1 Iron Ore
Reference ore SCH-1 was donated to CCRMP by the Iron Ore Company of Canada in 1973. It is from the Schefferville, Quebec, area and is hematite with a mixture of unidentified hydrous oxides of iron, minor magnetite, and trace pyrolusite. The gangue consists mainly of quartz with minor amounts of feldspar and traces of biotite, chlorite, and amphibole.
