Hello colleges
I am interested in the delamination process, which is important for the material exchange between mantle and lithosphere.
Sierra Nevada and Colorado Plateau are believed to have the lithospheric delamination.
And now, there are more and more regions reported by the delamination. Could you show some of your paper or references about it?
Thank you.
not sure if this is what you are after, but the attached shows the plausibility of delamination by crustal drips that might have been the dominant process of crustal recycling in the early archaean...
Thanks Dr. Tim, it helps. So where could be the regions as your paper?
Here a recent paper about mantel delamination :
Levander, A., M. J. Bezada, F. Niu, E. D. Humphreys, I. Palomeras, S. M. Thurner, J. Masy, et al. 2014. “Subduction-Driven Recycling of Continental Margin Lithosphere.” Nature 515 (7526): 253–56. doi:10.1038/nature13878.
Here is a good overview of areas where seismic interpretations have identified delaminated slabs in the western U.S.: Burkett and Gurnis (20113) Stalled slab dynamics: Lithosphere, v. 5, p. 92-97. (attached). Also, our own paper on one interpretation for these slabs (attached)
Hi Yanfang,
I include a reference where lithospheric delamination has been fingerprinted using Sm/Nd isotopes under western Europe (Iberia) in Early Permian times. Also a review paper on all the process. I hope it is of use!!

Dear Dr. Lafosse, Camp and Salamanca
Thanks for your sharing.
It seems that the delamination process could be observed from the geochemical and seismological method, and confirmed from the geodynamic modeling.
And the regions always took place beneath the archaean and subduction area.
Please keep informing me if you have any reference on the delamination.
Thanks and best wishes

You mentioned the Sierra Nevada so I don't know how many references you have for that already. But this is a pretty good example:
Zandt et al. 2004, Active foundering of a continental arc root beneath the southern Sierra Nevada in California: Nature, v. 431, p. 41-46.
You might also be interested in this study of the driving mechanisms:

I hope this helps.
Thanks Prof. Macpherson.
The first paper gave a clear image of the delamination from the seismic method.
It helps.

Dear Yangfan
you also can have a look at Koksal et al, 2001, Int. Geol. Rev, 43, 683-694 for products of LD in a post collisional setting. Full text is available in ResearchGate.

Dear Oguz
Thanks for your answer. The paper helps. I didn't know this region with this feature before.
Hope to cooperate with you in future.
Best wishes,
Yangfan
We launch a special issue concerning this topic in Terra Nova, welcome to submit if you have related studies.
