Abstract: The Zhongshan iron ore deposit is located in the north of the Luzong volcanic basin ,with ore bodies occurring mainly in andesite ,andesitic breccia and cryptoexplosive breccias .Ore types contain hem‐atite ore and magnetite ore .The genesis of the deposit belongs to low‐medium and medium‐high tempera‐ture hydrothermal metasomatism filling deposit .The geological features ,ore - controlling factors and ore‐forming process ,and exploration criteria and direction ,etc ,were summarized on the basis of the previous research results and geological data collected during mining process .This study is helpful in looking for i‐ron ore deposits of the same type in the Luzong volcanic basin and increasing the resource amount of iron ores in the Dazhongshan iron ore deposit ,providing some reference significance in deep and periphery pros‐pecting .
