Recent Ridge Eruptive Activity Dating and Investigations (The "Rreadi" Project)

小行星9633268 标题：最近海脊喷发活动年代测定和调查（“Rreadi”项目）。 与陆地上的火山爆发不同，没有观测到海底的火山爆发。海底火山喷发是无法接近的，通常无法通过陆地测量来检测，因此甚至不知道火山喷发何时发生。目前还没有技术可以确定这些熔岩的年龄，所以我们无法将海底喷发的样本按顺序放置。PI开发了一种技术，根据铀和钍衰变系列的短寿命子产物的数量来确定岩石的年龄。这项技术已经成功地确定了东太平洋海隆一次年轻喷发的年代。这项技术只适用于不到3年的样品，他希望将这项技术扩展到衰变系列，将样品的年代定到100年。

9633268 Rubin Title: Recent ridge eruptive activity dating and investigations (The "Rreadi" project). Unlike volcanic eruptions on land, there are no observations of eruption on the ocean floor. Undersea eruptions are inaccessible and usually can not be detected by on-land measurements, so it is not even known when eruptions occur. There are no techniques available to determine the age of these lavas, so we can not place samples from undersea eruptions in sequence. The PI has developed a technique to determine the age of rocks based on the amount of short-lived daughter products of the uranium and thorium decay series. This technique has been successful for dating one young eruption on the East Pacific Rise. This technique is only good for samples less than 3 years old, and he wishes to extend this technique to decay series that will date samples up to 100 years.
