Nihe Fe-S deposit is located in northwest of the Luzong volcanic basin on the metallogenic belt along the Middle-Lower reaches of Yangtze River, with Fe and S reserves up to the large scale and anhydrite reserves up to middle scale. It is one of the key breakthroughs in ore exploration and of great academic significance and exploration value. The main strata in the Nihe mine district are andesitic volcanic rocks and clastic rock of the Zhuanqiao Formation and Suangmiao Formations, while the main intrusive rock is pyroxene diorite porphyrite. Based on the geological characteristics of the Nihe iron deposit and comparison with the porphyry iron deposit in the Ningwu volcanic basin, the Nihe iron deposit has closely relationships with the pyroxene diorite porphyrite, and belongs to the "Taocun type" porphyrite iron deposit.
