The proven total reserves of iron ores in China are relatively abundant, but the iron ores mainly belong to low-grade ores. The main genetic types of iron deposits of high-grade ores in China includeminor-fareast; mso-hansi-font-family: calibri; mso-hansi-theme-font: minor-latin; mso-bidi-font-family: ’times new roman’">: 1minor-fareast; mso-hansi-font-family: calibri; mso-hansi-theme-font: minor-latin; mso-bidi-font-family: ’times new roman’">)hydrothermal reformed type in sedimentary metamorphosed iron deposits (BIF); 2) weathered leaching type in sedimentary metamorphosed iron deposits (BIF); 3) iron deposits related to continental volcano-intrusive activities; 4) iron deposits related to marine volcanic (intrusive) activities; 5) skarn iron deposits; and 6) hydrothermal iron deposits. Among these iron deposit types of high-grade iron ores, the skarn iron deposits and iron deposits related to marine volcanic (intrusive) activities are relatively important and have favorable ore-prospecting potential.
