安徽省铜陵市铁山头铜矿床地质特征及找矿潜力

铁山头铜矿床处于铜陵矿集区的中东部，属于扬子陆块下扬子凹陷中的铜陵隆起。矿床位于凤凰山矿田北侧，成矿潜力较大。综合研究分析认为：①接触交代作用使得岩体接触带及附近变质形成矽卡岩矿化带；②区内凤凰山岩体（花岗闪长岩）系成矿母岩；③矿体主要赋存于花岗闪长岩与三叠系下统南陵湖组石灰岩接触带上；④矿床成因类型为高—中温热液交代矽卡岩型矿床。

Geological Characteristics and Prospecting Potential of Tieshantou Copper #br#Deposit in Tongling City,Anhui Province

Tieshantou Copper Deposit is located in the middle east of Tongling ore concentration area,belonging to Tongling uplift in the Lower Yangtze depression of the Yangtze block.The deposit is located in the north side of Fenghuangshan ore field,with great metallogenic potential.The comprehensive analysis shows that:①Contact metasomatism makes the contact zone and its vicinity metamorphosed to form skarn mineralization zone;②The Fenghuangshan rock body (granodiorite) is the ore forming parent rock;③The ore body mainly occurs in the contact zone between granodiorite and limestone of nanlinghu formation of Lower Triassic;④The genetic type of the deposit is high to medium temperature hydrothermal metasomatic skarn type.
