宁芜向山－皇姑山地区，黄铁矿床赋存于基底火山喷发带、火山穹窿和NNE与NW向基底断裂交汇部位。通过多种手段综合研究，证实该区NNE向基底断裂为导矿构造，NE、NNE、NW向断裂构造为容矿构造。该区中生代二期构造应力场中NWW—SEE向主压应力场之共轭角高值区为黄铁矿富集地带。矿床受火山构造和地质构造双重控制，在皇姑山、莺子山、濮塘地区，云台山NE、SW方向，可能找到隐伏的黄铁矿矿床。
Ning Wu Xiangshan - Huang Gushan area, pyrite deposits occur in basaltic volcanic eruptions, volcanic domes and NNE and NW to the basement of the intersection of the fracture site. Through a comprehensive study of various means, it is confirmed that the NNE-trending basal faults in this area are the ore-bearing structures and NE, NNE and NW trending faults are the ore-hosting structures. The conformational angle of the NWW-SEE to the main compressive stress field in the tectonic stress field of the second generation of Mesozoic in this area is a pyrite enrichment zone. The deposit is controlled by both volcanic structure and geological structure. Concealed pyrite deposits may be found in the Huanggushan, Yingzishan, Puntang, Yuntaishan NE and SW directions.
