二叠纪&三叠纪（P-T）之交发生了地质历史上规模最大的生物灭绝事件，因此，学者十分关注P-T界线地层中是否能检测到天然富勒烯的的存在。

The P-T event boundary strata have been long time of the scientists ' interests and puzzles because of the largest mass extinctions in the history of geology during Permian-Triassic boundary .

锆石U-Pb同位素测定显示，该岩体不同岩相岩石具有大体一致的年龄，其形成于120～130Ma的早白垩世，而不是以前认为的三叠纪。

Zircon U-Pb isotopic dating for different petrographic rocks gives similar emplacement ages ( 130 ~ 120 Ma ), i.e. , the Early Cretaceous , not the Triassic as previously thought .
