应用热年代学方法，揭示了燕山南缘盘山岩体的热历史与隆升过程。结果表明， 盘山岩体的侵位深度约为 １０ｋｍ 。岩体侵位以后， 经历了快速冷却过程，在２２６４８ Ｍａ～２０４９５ Ｍａ 期间，岩体温度由 ５２０℃冷却至 ３００℃， 平均降温速率为１０２２℃／ Ｍａ。２０４９５ Ｍａ～１１８ Ｍ ａ 期间为盘山岩体的缓缦隆升时期，平均隆升速率约为 ００２８ｍ ｍ ／ａ，隆升幅度约 ２５ｋｍ 。１１８ Ｍａ～９６ Ｍａ 为盘山岩体较快速隆升时期，隆升速率为００３５ｍ ｍ ／ａ，隆升幅度约０７７ｋｍ 。９６ Ｍａ～３５ Ｍａ 为盘山岩体与盘山山脉的快速隆升时期，隆升速率约为０１１５ｍ ｍ ／ａ，隆升总幅度达７ｋｍ 。３５ Ｍａ 以来，盘山岩体的隆升速率很小，仅约００１４ｍ ｍ ／ａ，隆升幅度约为０５ｋｍ 。盘山周缘环状构造系统的形成时代略早于 ２２６４８ Ｍａ，盘山南缘边界正断层的活动时代为中生代末～始新世 Using the method of thermochronology, the thermal history and uplifting process of the Panshan granite in the southern Yanshan Mountains are revealed. The results show that the emplacement depth of Panshan pluton is about 10km. After the emplacement of the rock mass, it experienced a rapid cooling process. During 22648 Ma ~ 20495 Ma, the temperature of the rock mass was cooled from 520 ℃ to 300 ℃ and the average cooling rate was 1022 ℃ / Ma. The period from 20495 Ma to 118 Ma is the gentle  uplift period of Panshan granite. The average uplift rate is about 0028 m / a, and the uplift is about 2  5 km. The 118 Ma ~ 96 Ma is the rapid uplifting period of the Panshan massif with an uplift rate of 0035 m / a and an uplift of about 077 km. The 96 Ma ~ 35 Ma is the rapid uplifting period of the Panshan massif and the Panshan Range. The uplift rate is about 0115 m / a, and the total uplift rate is up to 7 km. Since 35 Ma, the uplift rate of the Panshan massif is very small, only about 0014m m / a, and the uplift rate is about 05km. The epicenter of Panshan peripheral ring structure system was slightly earlier than 22648 Ma. The active epoch of the boundary faults along the southern margin of Panshan is from the end of Mesozoic to Eocene
