Incompatible element

TL;DR: In this paper, the authors present smoothed particle hydrodynamics simulations of collisions between differentiated rocky planetesimals and planetary embryos and find that the crust is preferentially lost relative to the mantle during impacts, and they have developed a scaling law based on these simulations that approximates the mass of crust that remains in the largest remnant.

TL;DR: The Wuchagou and Halaha volcanic fields are located in the central Great Xing'an Range, Northeast China, cover an area of ~ 1400 km2 in China, and continue westward into Mongolia.

TL;DR: In this paper, a suite of well-characterised lavas from the Mariana Islands were measured and the results showed that the U-series isotope compositions of these lavas are more strongly controlled by the initial compositions of the slab components than by mantle melting.

TL;DR: In this paper, a suite of picrite basalts from Nuanetsi in the Karoo CFB province were used to define the Pb isotope characteristics of this end-member more precisely.

TL;DR: The Madagascan ankaratrites of the Alaotra, Takarindoha-Vatomandry and Votovorona (NE Ankaratra) volcanic fields, Madagascar, range from olivine (±monticellite) melilitites, through olivines-melilite nephelinites to olivinedite (±leucite) nepheminites, and evidence of distinct parental magmas, often in different facies of the same vent.
