摘要
秦岭成矿带夹持于华北克拉通与扬子板块之间,先后经历多期强烈的构造演化事件,是我国金、钼、铅锌、铁等金属矿产的优势矿产资源区之一。该成矿带内其复杂性与特殊性备受地学界广泛关注。河南省南召县红石寨铁铜铅多金属矿位于北秦岭成矿带东段,通过研究矿床地质特征及地球物理特征表明,区内铁、铅和铜锌矿为形成于加里东期地壳的拉伸环境下属火山热液沉积型块状硫化物矿床。不同于传统认识,笔者认为铅锌矿为形成于印支期充填型的铅锌矿,通过深入研究红石寨矿床地质特征并探讨其成矿地球动力学背景,为北秦岭成矿带复杂性与“非典型”性特征研究拓展新空间。
The Qinling metallogenic belt is sandwiched between the North China Craton and the Yangtze Plate,and has experienced multiple periods of intense tectonic evolution events.The complexity and particularity of this metallogenic belt have attracted extensive attention from the geoscientific community.The Hongshizhai iron-copper-lead polymetallic deposit in Nanzhao County,Henan Province is located in the eastern section of the North Qinling metallogenic belt.The study of the geological and geophysical characteristics of the deposit shows that the iron,lead and copper-zinc deposits in the area were formed in the Caledonian crust.It was a volcanic hydrothermal sedimentary massive sulfide deposit in a tensile environment.Different from traditional understanding,the author believed that the lead-zinc deposit was a filling type lead-zinc deposit formed in the Indosinian period.Through in-depth study of the geological characteristics of the Hongshizhai deposit and discussion of its metallogenic geodynamic background,it was the complexity of the North Qinling metallogenic belt.Expand new space would the study of"atypical"characteristics.
