The lithospheric mantle and lower crust-mantle relationships under Scotland: a xenolithic perspective [PDF]
, 2011 In the British Isles the majority of volcanic rocks containing upper mantle and lower crustal xenoliths occur in Scotland. Most of the occurrences are of Carboniferous–Permian age.

CO 2 Solubility in Kimberlite melts CO 2 Solubility in Kimberlite melts [PDF]
, 2015 International audienceCarbon dioxide is the most abundant volatile in kimberlite melts and its solubility exerts a prime influence on the melt structure, buoyancy, transport rate and hence eruption dynamics.

Kimberlite ascent and eruption [PDF]
Nature, 2007 Wilson and Head model kimberlite ascent and eruption by considering the propagation of a volatile-rich dyke. Wilson and Head's model has features in common with Sparks et al., but it is inconsistent with geological observations and constraints on volatile solubility. Here we show that this may be due to erroneous physical assumptions.

Mathematical methods of search for diamond-bearing areas and kimberlite fields in closed territories
Мінеральні ресурси України, 2018 Based on the analysis of the interrelationships between real kimberlite fields and the location of kimberlite tubes of the world, a structural and mathematical method for the search for diamond-bearing regions and kimberlite fields is proposed.

Olivine in the Udachnaya-East kimberlite (Yakutia, Russia): types, compositions and origins [PDF]
, 2007 Olivine is the principal mineral of kimberlite magmas, and is the main contributor to the ultramafic composition of kimberlite rocks. Olivine is partly or completely altered in common kimberlites, and thus unavailable for studies of origin and evolution ...

Cation Exchange in Smectites as a New Approach to Mineral Carbonation
Frontiers in Climate, 2022 Mineral carbonation of alkaline mine residues is a carbon dioxide removal (CDR) strategy that can be employed by the mining industry. Here, we describe the mineralogy and reactivity of processed kimberlites and kimberlite ore from Venetia (South Africa ...
