The Iron Mountain District, also known as the Iron Springs District, is a large, high-grade iron deposit〔Bullock, K. C., 1970, Iron Deposits of Utah, Utah Geological and Mineral Survey Bulletin 88, 102 pgs.〕 in southwestern Utah, near Cedar City. It is currently in care and maintenance status (not actively producing iron ore) by CML Metals Corporation, a division of Palladon Ventures and Luxor Capital. Previous owners include Geneva Steel and U.S. Steel. The district is made of three primary topographic highs along a ~17 mile lineament: Iron Mountain to the southwest, Granite Mountain in the middle, and Three Peaks in the northwest. Mineralization in this district occurred as rings around the highs as a skarn, a replacement of existing carbonate rock material with high-grade iron ore, mostly in the form of high-grade (>50%Fe in places) magnetite, but also locally hematite. Minor pyrite is also present. Hot fluids are sourced from mid-Tertiary intrusions, which core all three areas. Major areas of iron deposits and their associated mines/pits/ore bodies include: *Iron Mountain * *Blowout * *Blackhawk * *Comstock * *Mountain Lion * *Tip Top * *Pinto * *Chesapeake * *Excellsior * * Homestake *Granite Mountain * *Desert Mound * *Queen of the West *Three Peaks ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Iron Mountain District」の詳細全文を読む スポンサード リンク
