如果能够直接测定组成沉积物的矿物颗粒的年代,那么,地质事件和考古事件的年代测定将更为容易。现在,沉积物的年代测定几乎完全依靠有机质的放射性碳年代测定,但它同时存在测量面小、时代限制和组合等问题。这里,我们论证了一种直接测定沉积物颗粒年代的新方法。调零机制是阳光,推测所获得的年代与该沉积物沉积的年代相一致。 Chronology of geological events and archeological events will be easier if the age of the minerals that make up the sediment can be measured directly. Chronology of sediments is now almost entirely dependent on the dating of organic carbon, but at the same time there are issues such as small measurement times, age limitations and combinations. Here, we demonstrate a new method to directly measure the age of sediment particles. The mechanism of zeroing is sunlight, suggesting that the age obtained is consistent with the age at which the sediment was deposited.
