The Huoqiu iron ore field was explored in 1960s by the No. 337 Geological Team of Anhui Provincial Bureau of Geology. Successive exploration work was carried out focusing on the defined deposits and surrounding areas of exposures by drill and detailed field mapping. The geophysical work was undertaken using airborne magnetic surveys, ground electrical and gravity surveys, which covered the entire Huoqiu ore field region. The Huoqiu iron ore field is proven to be a large ore field characterized by BIF, consisting of quartz, magnetite and hematite (or specularite) phases hosted in amphibole schist, plagioclase gneiss, and amphibolite. According to the rock associations, the Huoqiu Group can be divided into two series and three succession formations (i.e. Huayuan Fm., Wuji Fm. and Zhouji Fm.). The protolith of Huoqui Group is considered to be formed by a basic volcanicsedimentary cycle.
