摘　　要：大安山铁铜矿床位于宁芜断陷盆地中段。该矿床铜矿体呈似层状、脉状产出于龙王山组火山岩及黄马青组砂岩的破碎带中;铁矿主矿体产于闪长岩体和黄马青组砂页岩接触带部位,矿体在空间上呈"上铜下铁"的分布特征。通过对矿床地质特征、地质成矿规律研究分析,并将其与宁芜地区类似的矿床地质特征对比,认为大安山铁铜矿是一个兼具大平山式铜矿、白象山式铁矿的一个复合型矿床。在大安山矿区具有很大的找矿潜力。Daanshan Fe-Cu deposit is located in the central part of Ningwu(Nanjing-Wuhu)faulted basin.The copper orebody of the deposit occurs as stratoid or veined in form in the fracture zone of volcanic rocks of Longwangshan Formation and sandstone of Huangmaqing Formation.The main iron orebody occurs in the contact zone of the diorite rock bodies and the sandshale of Huangmaqing Formation.The spatial distribution of the orebodies are characterized by “upper-copper and lower-iron”.The study and analysis on geological characteristics and geological metallogenic regularity of the deposit and the comparison of the geological char-acteristics of the deposit with other similar deposits in Ningwu area indicates that Daanshan Fe-Cu deposit is a compound deposit which has the characteristics of both Dapingshan type copper deposit and Baixiangshan type iron deposit.In conclusion,Daanshan mining area has great prospecting potential.
