| 摘 要： | MDD法和裂变径迹法是2种最常用的低温热年代学方法.通过对它们的测试结果的模拟,揭示出样品经历的热历史,可以有效地延伸这2种方法的研究范围.但是由于模拟的多解性,使得如何制约模拟过程,获得合理的模拟结果显得尤为重要.通过柴达木盆地北缘的模拟过程,展示了模拟中可能存在的问题及提高模拟结果的方法.同时揭示了柴达木盆地北缘中...

| Abstract: | K-Feldspar MDD(Multiple Diffusion Domain)and fission track are two commonly-used methods in low closure temperature thermal chronometry.By modeling both the feldspar 39Ar/40Ar data and the fission track age and track-length data,the thermal history that sample underwent can be revealed and the effective temperature range of both feldspar 39Ar/40Ar method and fission track method is extended.Because of the multiple resolution of modeling,it is important to restrict the modeling process to gain a reasonable r... |
