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。河北下营坊金矿区成矿温度为：早期矿化370—290℃，主要成矿期230—170℃，成矿晚期150—80℃。石英-绢云母化带锆石和磷灰石的裂变径迹年龄分别为153．9Ma和1033Ma。由于锆石和磷灰石裂变径迹封闭温度通常分别为250℃和110℃，所以这是主要成矿时代的体现，成矿时问持续50Ma以上。

Abstract

The mineralization temperature of the Xiayingfang gold deposit in Hebei is 370-290℃

230-170℃ and 150-80℃ in vanward-

main- and late-mineralization periodrespectively. Fission track ages of the zircon and apatite from the quartzsericitization zone of the gold district are 153.9Ma and 103.3Ma

respectively. Theages fall into major mineralization. time

and the metallogenetic period is more than50Ma. It is shown that fission track analysis of the minerals is useful to researchingthe metallogenetic epoch of hydrothermal deposits.
