摘要
矿物的裂变径迹年龄分析可有效地用于热液矿床成矿时代的研究。对金顶超大型铅锌矿床的成矿年龄存在不同的看法，本文以架崖山矿段为代表，采用磷灰石裂变径迹分析方法测定了金顶铅锌矿床的成矿年龄。结果表明：金顶铅锌矿床的成矿期在渐新世，其后遭受了喜马拉雅造山运动的热扰动。
： Fission track analysis of minerals may be effective in the study of the metallogenic epoch of hydrothermal deposits.There exist different views on the metallogenic age of the Jinding super－ large lead－ zinc deposit.Taking the Jiayashan ore block as an example,the paper studied the metallogenic epoch of the Jinding lead－ zinc deposit with apatite fission track analysis.The result shows that the metallogenic age of the Jinding lead－ zinc deposit is the Eocene,and later,the deposit had undergone thermal disturbance of the Himalaya orogenic movement.
