Tongling Ore Concentration Area in Anhui Province is an important metallogenic area in the Middle-lower Yangtze Reaches Metallogenic Belt.The Dilongchong Gold Deposit is located in the middle of the ore concentration area,with the tectonic position on the northern margin of the Yangtze Plate.In recent years,typical deposits such as Yeshan Iron Deposit,Caojiachong Copper Deposit,Shujiadian Copper Deposit,and Yangchongli Gold Deposit have been discovered in this area.Through this field exploration work,combined with the existing achievements of the predecessors,the geological characteristics,metallogenic elements,and prospecting indicators of the Dilongchong Gold Deposit are systematically summarized,which provides a basis for further prospecting and exploration work.The results show that the metallogenic types of Dilongchong Gold Deposit are mainly fissure filling types and altered rock types.The genesis of the ore body (vein) is considered to be the late hydrothermal infusion,filling,or metasomatism mineralization.The ore bodies (veins) in the area are strictly controlled by the structure,and the NE-trending main structure and the NW-trending secondary structure are both ore-hosting structures.The intersection of the Fentou Formation,quartz diorite porphyry,and fault structure contact zone and its vicinity are key positions for finding gold deposits.The 4 mineralization alteration combinations of silicification-specularite mineralization-pyritization (limonite mineralization),specularite mineralization-gold mineralization,silicitization-pyritization,and beresitization are important prospecting indicators in the mining area and surrounding areas.
