Specific features of petrographic study of kimberlite
View through CrossRef
Based on the analysis of specific actual and analytical material capabilities and perspectives of petrographic and petrological investigations of kimberlite rocks are indicated. Kimberlite is a volcanic igneous rock, undersaturated by silica, enriched in volatiles of peralkaline ultramafic hybrid formations, containing mantle and crust material in varying quantities and ratios. Mantle material in kimberlite is represented by xenoliths of ultramafic, alkali-rich mafic-ultramafic rocks and xeno-minerals from them.
