英文摘要	As an important part of multi-metal concentration metallogenic belt in the Middle and Lower Yangtze River, the deep structure and mineralization process of Luzong ore district have been concerned. This paper carries out the objective process method with the existing gravity and magnetic data, such as matching filter, analytical continuation and derivation etc. Gravity and magnetic anomaly characteristics of Luzong ore district are further depicted, and much structure information is revealed, including metallogenic belts, orebodies, fractures, basement uplifts and basin sinks. Based on these data, combined regional geology and mineral distribution of Luzong ore district, we draw some conclusions. Luzong ore district includes four metallogenic belts, which composed by Tanlu fracture belt, Peigang-Zhugiao fault, Luohe fault and the Yangtze River fracture, and its general trend extends southwest to northeast. Luzong ore district can also be divided into five parts, which are Luzong volcanic basin, Kongcheng sag, upwarping folded zone from south Chaohu to LuJiang, eastern margin of Dabie orogenic belt and the Yangtze River depression. As ore deposits diversification, deposits and mineralization show belt and circular characteristics distribution. Volcanic tectonic and volcanic magma activity restricts the distribution of iron, sulfur, and copper (gold) ore bodies, and basement uplift and fracture of Luzong ore district play an important controlling role. The residual gravity and magnetic anomalies after anomaly separation are the important comprehensive information signs to look for rest of iron ore. The superposition area of gravity anomaly and low-pitched magnetic anomaly in high background still has large prospecting potential.
