Deep recycling of crustal materials by the Hainan mantle plume: evidence from Zn–Sr–Nd–Pb isotopes of Hainan Island basalts
Understanding the compositional heterogeneity of the deep mantle requires identifying the nature of recycled crustal materials in the sources of...

Earth’s mantle composition revealed by mantle plumes
Mantle plumes originate at depths near the core−mantle boundary (~2,800 km). As such, they provide invaluable information about the composition of...

Magmatism of Shatsky Rise controlled by plume–ridge interaction
Shatsky Rise is a large oceanic plateau formed at a spreading ridge triple junction, but its origin mechanism is unclear. Voluminous magmatism at...

Mineralogy and geochemistry of trachytic rocks from the Lichi Volcanics, Eastern Himalaya: insights into the Kerguelen mantle plume activity in the Eastern Himalayan Region
The Lichi volcanics are a suite of mafic-intermediate-felsic rocks and are considered coeval with the Abor volcanics (~132 Ma) of the Siang window in...
