Hematite Breccia-Hosted Iron Oxide Copper-Gold Deposits

The Prominent Hill deposit is a large iron oxide copper-gold (IOCG) resource located in the Olympic IOCG province of South Australia. The deposit is hosted by brecciated sedimentary rocks and structurally underlying lavas of the ca. 1.6 Ga Gawler Range Volcanics. Both rock units are altered and mineralized, forming characteristic hematite breccias.

Gold in iron oxide copper–gold deposits ScienceDirect

2016-1-1  Abstract. Iron oxide copper–gold (IOCG) deposits contain economic or anomalous gold, and the gold distribution is important both for its economic significance and ore genesis. However, the gold distribution in IOCG deposits and its controlling factors remain unclear. The gold grades and tonnages of selected thirty-six deposits in some well

Iron Ore Sedimentary Rock Pictures Definition amp More. Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ).
