Dynamical constraints on kimberlite volcanism
TL;DR: In this article, the authors proposed a four-stage model for kimberlite eruptions to explain the main geological relationships of kimbersites, where the early flow exit conditions are overpressured with choked flow conditions; an exit velocity of ∼200m/s is estimated as representative.

Post-emplacement serpentinization and related hydrothermal metamorphism in a kimberlite from Venetia, South Africa
TL;DR: The Venetia Mine, South Africa, is attributed to a secondary origin, because of post-emplacement serpentinization and associated hydrothermal metamorphism as mentioned in this paper.

TL;DR: In this paper, the authors investigated three putative kimberlite melt compositions and found that they are not consistent with the groundmass mineralogy that indicates significantly lower SiO2 in the natural systems.

3D crystal size distributions : a case study on quantifying olivine populations in kimberlites.
TL;DR: In this paper, the application of 2D and 3D textural analysis to the quantification of olivine populations in kimberlites is investigated, and the 3D data set provides accurate analysis over a range of 6-~0.5mm.

The volatile content of hypabyssal kimberlite magmas: some constraints from experiments on natural rock compositions
TL;DR: In this article, the authors performed experiments on some putative primary kimberlite magma compositions to assess the amount of CO2 and H2O retained if these compositions represent magma as it entered the root zone.
