地质年龄的测定在地质科学领域内占有重要的位置,近年来较普遍应用的测定方法有 C~(14)、K-Ar、热发光、古地磁、氨基酸等。应用上述各种方法直接或间接地确定地质年龄。但由于受方法本身的条件所局限,其测定范围受到一定限制,而氨基酸年龄测定法对于测定新生代沉积物的年龄有其一定的优越性。同时,近代氨基酸对映体的测定还可以用于确定样品是否存在现代污染。所以,氨基酸年龄法虽问世时间不长,却引起了地质界的广泛注意。
Geological age determination in the field of geology occupies an important position in recent years, more commonly used determination of C ~ (14), K-Ar, thermal luminescence, paleomagnetism, amino acids and so on. Geological ages are determined directly or indirectly using the various methods described above. However, due to the limitation of the conditions of the method itself, the determination range is limited, and the amino acid age determination method has certain advantages for determining the age of Cenozoic sediments. At the same time, the determination of modern amino acid enantiomers can also be used to determine whether samples are presently contaminated. Therefore, although the amino acid age method is not available for a long time, it has aroused widespread attention in the geological community.
