In recent years,a number of small-and medium-sized gold deposits have been found in the Wuhe area,an important gold mineralization zone in Anhui Province,showing a good prospect for further discovery.However,it is an area of widespread overburden,where bedrocks rarely outcrop,adding to the difficulty in mineral exploration.The Fang'an gold deposit is a small one unveiled in the area in 2020.After analyzing its mineralization and geological characteristics,this paper summarizes its ore-controlling conditions.With the mineralization laws of gold deposits in the area being taken into consideration,it is suggested that the NE-NNE trending fault structure has a dominant control over the quartz vein type and structurally altered rock type gold deposits.Magnetic anomaly gradient zone may be used to find the concealed fault zone for mineral exploration in the future.At the same time,efforts shall be made to explore gold deposits in the deep-seated area.
