Abstract: Xiangtang Iron Deposit in Maanshan City is located at the southeast margin of Nanshan Iron Deposit，which is distributed at the south section of Ningwu Mesozoic volcanic basin.Xiangtang Iron Deposit is located at 16 km to the 120° direction of Maanshan City，it is about 8 km away from Xiangshan Town in Maanshan City.Based on the related geological working results of the mining area，the deposit geological characteristics and genesis are studied.The study results show that:①Xiangtang Iron Deposit is a typical high-medium temperature gas-liquid metasomatism type porphyrite deposit，it belongs to “Taocun type” iron deposit in porphyrite series，a total of 17 iron orebodies are found in the mining area，they are mainly occurring in pyroxene diorite porphyrite rock mass；②the ore minerals are mainly for magnetite，followed by pseudomorphic hematite，hematite and lignite，and a small amount of specularite and siderite，most of the natural ores are diorite porphyrite disseminated magnetite ores.Based on the above discussion results，the further discussion results indicated that:①pyroxene diorite （porphyrite） rock mass of Dawagnshan cycle is the prospecting rock indicator for porphyrite iron deposit；②the intersecting position of fault structures，breccia structure and zonal shrinkage fracture zone are the important structural prospecting indicators for “Taocun type” iron deposit；③the surrounding rock alteration is strongly developed and the alteration zoning characteristics is obvious，which are the favorable prospecting indicators in the mining area；④the characteristic vein body or mass is an important clue to search for deep and lateral porphyrite iron deposit；⑤magnetic anomaly and gravity anomaly are the favorable indirect indicators for the exploration of iron deposits in the mining area.
