Magmaclast from a vulcanoclastic kimberlite in thin section.
Magmaclasts are the “hallmark” of the KPK variety and don't occur in hypabyssal kimberlites.
More about Kimberlite petrology: Mitchell, R. H., Giuliani, A., & O'Brien, H. (2019, December). What is a Kimberlite? Petrology and Mineralogy of Hypabyssal Kimberlites. Elements, 15(6), 381–386. https://doi.org/10.2138/gselements.15.6.381
The Elements Magazine has an issue about Kimberlites and it's very interesting to know more about them.
