摘要
大多数学者认为凤太矿集区铅锌矿属热水喷流沉积(SEDEX)–改造(再造)型,矿体产出受地层、构造及岩相三位一体控制;最近几年受造山型成矿理论影响,部分学者认为凤太矿集区铅锌矿属后生热液矿床。成矿理论的深入研究对该区的找矿具重要的指导意义,笔者认为凤太矿集区铅锌矿床为后生热液成矿,矿体受不同岩性界面控制,并不局限于泥盆系,从而拓展了找矿视野。
Most scholars believed that the deposit in Feng-Tai Pb-Zn deposit cluster area belongs to the type of hydrother- mal venting-flowing sedimentary （SEDEX）-renovation （reconstruction） and the output of orebody is controlled by the Trini- ty of ore formation, structure and petrofacies. Under the influence of orogeniemetallogenic theory in recent years, some scholars believethat the Pb-Zn deposit in the Fengtai ore concentrated area is epigenetic hydrothermal ore deposits. Deep study on melallogenic theory has guiding significance in the area. The author believes that the lead-zinc deposit in Fengtai ore concentration area is the epigenetic hydrothermal type, and the orebody is controlled by multiple lithological interfaces, and is not limited to the Devonian, which expands the exploration vision.
