Olivine chemistry reveals compositional source heterogeneities within a tilted mantle plume beneath Iceland
Abstract High-Fo olivine (Fo= Mg/(Mg+ Fe) mol%) is an ideal proxy for establishing the
compositions of primary melts and their mantle sources. This has been exploited in …

Thermal-chemical conditions of the North China Mesozoic lithospheric mantle and implication for the lithospheric thinning of cratons
Cratons are the most ancient parts of continents that are underlain by thick, cold, old and
refractory lithospheric roots. However, how cratonic roots remain stable for billions of years …

Cu‐isotope evidence for subduction modification of lithospheric mantle
Ultramafic xenoliths from southeastern Arizona, USA, provide evidence for Cu‐isotope
heterogeneity in the lithospheric mantle. We report new data on Type I (Cr‐, Mg‐rich) …

Compositional variations in primitive kimberlite melts and entrained mantle cargo from a global survey of trace element compositions in kimberlite olivine
Olivines are the dominant phase of kimberlites and the majority of grains display distinct
compositional zoning with xenocrystic cores surrounded by magmatic rims. Previous work …
