对云南哀牢山混合岩、淡色花岗岩锆石的U-Pb同位素测试计算得到的年龄数据,数据包括Th (ppm)、U (ppm)、Th/U ratio、207Pb/206Pb、207Pb/235U、206Pb/238U、Rho、207Pb/206Pb Age (Ma)、207Pb/235U Age (Ma)、206Pb/238U Age (Ma)、1σ等。
Because of their robustness against resetting, in situ U-Pb ages of zircons in lunar impactites have the potential to provide constraints on the lunar bombardment history that may complement the more
Evidence of millennial-scale cold events following the last interglacial are well preserved in North Atlantic marine cores, Greenland ice, and pollen records from Europe. However, their timing was pre
