DOI: 10.1002/2017tc004796
Abstract: Upwelling mantle plumes beneath continental crust are predicted to produce difficult to quantify, modest uplift and denudation. The contribution of permanent and transient components to the uplift is also difficult to distinguish. A pulse of… read more here.

DOI: 10.1016/j.jseaes.2019.104145
Abstract: Abstract During the Permian, Emeishan mantle plume activity created a large igneous province and deeply impacted carbon isotope records in marine carbonate strata in South China. To evaluate the isotopic variations caused by this catastrophic… read more here.

DOI: 10.1016/j.pepi.2019.106316
Abstract: Abstract A mushroom-like low-velocity body (MLLVB) was defined by tomography beneath Northeast China, which may be linked to a vestige of the Mesozoic upwelling mantle plume. However, multiple lines of evidence indicate that the necessary… read more here.

DOI: 10.1016/j.tecto.2017.12.027
Abstract: Abstract The Emeishan large igneous province (ELIP) is widely considered to be a consequence of a mantle plume. The supporting evidence includes rapid emplacement, voluminous flood basalt eruptions, and high mantle potential temperature estimates. Several… read more here.

Crustal Formation on a Spreading Ridge Above a Mantle Plume : Receiver Function Imaging of the Icelandic Crust
Sign Up to like & getrecommendations! Published in 2018 at "Journal of Geophysical Research"
DOI: 10.1029/2017jb015121
Abstract: Iceland sits astride a mid‐ocean ridge underlain by a mantle hot spot. The interplay of these two geological processes has the potential to generate a complex and laterally variable crustal structure. The thickness of the… read more here.

DOI: 10.1038/s41467-019-10832-7
Abstract: The geochemical variabilities in intraplate basalts (IB) from the West African passive margin (WAPM) region, have generally been employed to indicate the presence of recycled materials in an associated upwelling mantle plume. However, the absence… read more here.

DOI: 10.1038/s41561-019-0446-z
Abstract: Partial melting of Earth’s mantle generates oceanic crust and leaves behind a chemically depleted residual mantle. The time-integrated composition of this chemically depleted mantle is generally inferred from basalts produced at mid-ocean ridges. However, isotopic… read more here.
