对哈巴河岩体的磷灰石和锆石进行了裂变径迹测年。磷灰石的裂变径迹年龄为 5 1.1—76 .9Ma ,锆石的裂变径迹年龄为 14 1— 14 9Ma。根据磷灰石中自发裂变约束径迹长度的测量数据和Laslett的数学模型对岩体的古地温变化规律 (T -t轨迹 )进行了模拟 ,并结合其他矿物和方法的实测年龄值和封闭温度原理讨论了该区的热历史和隆升历史。
Fission track dating of apatite and zircon from the Habahe pluton was carried out. Apatite fission track age of 5 1.1-76 .9Ma, zircon fission track age of 14 1-14 9Ma. According to the measurement data of spontaneous fission restrained track length in apatite and the Laslett mathematical model, the paleopathological change (T -t trajectory) of rock mass is simulated. Combined with the measured age value of other minerals and methods and the closure temperature The principle discusses the area’s thermal history and uplift history.
