Periodic instability and restoration of cratonic lithosphere
《National Science Review》2025年第3期418-436,共19页Lijun Liu Ling Chen Zebin Cao Xiaotao Yang Andrea Stevens Goddard Rixiang Zhu 
supported by the Strategy Priority Research Program(Category B)of the Chinese Academy of Sciences(XDB0710000);the National Natural Science Foundation of China(92355302)to L.L.
The longevity of cratons usually implies that the entire cratonic lithosphere remained unchanged over billions of years,which is traditionally attributed to their intrinsically buoyant and strong lithospheric roots.By...

The effects of local variations in conditions on carbon storage and release in the continental mantle被引量：1
《National Science Review》2024年第6期15-29,共15页Stephen F.Foley Chunfei Chen Dorrit E.Jacob 
Our work on the carbon cycle is funded by the Australian Research Council(FL180100134 to S.F.F.and DP210101268 to D.E.J.).
Recent advances indicate that the amount of carbon released by gradual degassing from the mantle needs to be revised upwards, whereas the carbon supplied by plumes may have been overestimated in the past. Variations i...
