摘要

对低温Al芯电子自旋共振（ESR）测年进行了初步的探讨．在98K的低温条件下，得到了分辨率较高的Al芯ESR全峰图形．通过对三块不同深度的花岗片麻岩中Al芯的测定，从浅到深分别得到了1．141．10、0．50Ma的实验结果．这个结果与岩石形成的地质背景相一致。由此证明用ESR的Al芯来测定浅成变质岩的年龄是完全可行的．

Abstract

The Al-center ESR dating was briefly introduced. The Al- center ESR full-peak spectra were obtained at 98K for three samples of gneiss from different depths

and their ages were deduced to be 1.14Ma

1.10Ma and 0.50Ma respectively. The results were in accordance with the geologic background

thus proving that this technique is feasible for dating of hypabyssal metamorphic rock.
