云台山硫铁矿矿床位于宁芜火山岩盆地北段，矿体主要产于中三叠统黄马青组碳酸盐岩、钙质泥岩及粉砂岩中，少部分矿体产于上侏罗统龙王山组火山岩系。其产状与地层产状一致，明显受层位的控制。根据硫同位素及地层中硫的含量分析，其成因类型应属以层控为主体，并伴有热液成因的复合矿床。黄马青组提供了主要的硫源，火山活动对成矿也起到重要的作用
The Yuntaishan pyrite deposit is located in the northern segment of the Ningwu volcanic basin. The orebodies are mainly produced in the carbonate rocks, calcareous mudstones and siltstones of the Middle Triassic Huangmaqing Formation, and a few of the ore bodies are produced in the Upper Jurassic Dragon Wangshan volcanic rock series. The occurrence of the formation consistent with the formation, obviously under the control of the horizon. According to the analysis of sulfur isotopes and the content of sulfur in the strata, the genetic type should belong to the complex controlled deposits with the layer control as the main body and accompanying hydrothermal origin. Huangmaqing Formation provides the major sulfur source and volcanic activity also plays an important role in mineralization
