中文摘要
小行星9504536 这个项目将试图改进鱼牙齿化石中锶同位素的使用,以精确控制否则无法确定年代的沉积物的年龄。 两个问题将得到解决,一个处理的最佳清洁方法,以消除所有涂层和第二个检查证据的改变(成岩作用)的牙齿本身。 ***
英文摘要
9504536 Jones This project will attempt to refine the use of Sr isotopes in fossil fish teeth for precise age control of otherwise- undatable sediments. Two questions will be addressed, one dealing with the best cleaning method for removal of all coatings and the second examining evidence for alteration (diagenesis) of the teeth themselves. ***
