用光释光测年技术对河南偃师商城宫城部分宫殿和围墙基址夯土进行了定年。在夯土基址的建造过程中

有些石英颗粒可能见光而使其光释光信号被释放回零

光释光‘时钟’重新开始时。本文用单片再生剂量法测量了夯土中粗颗粒石英的等效剂量

测得的等效剂量值的分布说明石英颗粒的光释光信号在基址建造过程中有不同程度的晒退。据晒退相对彻底的石英颗粒得出的夯土光释光年龄分别是 4 .0ka、2 .2ka和 2 .5ka。尽管这些年龄值与考古年龄存在差异

但表明用光释光测年技术对宫殿建筑基址夯土进行定年是可行的

The tamped earth from the construction base of the city walls in the Yanshi walled city in Luoyang

China

was dated using the optical dating technique. The optical ages of the tamped earth samples are 4.0ka

2.2ka and 2.5 ka respectively. Although these ages are older or younger than the archaeological ages

which imply that some quartz grains were exposed to daylight during the construction of the city walls

the optical dating technique is suitable for dating tamped earth.
