Microminerals in Kimberlites
The peculiarities of kimberlite micromineral assemblages are described. The previous investigations results are analyzed and presented in the paper as well. The typical microminerals (main grains less than 5 µm in size) in 7 kimberlite tubes of Yakutiya (Nachalnaya, Novinka-1, 2, 4, Vodorazdelnaya,...

Summary: | The peculiarities of kimberlite micromineral assemblages are described. The previous investigations results are analyzed and presented in the paper as well. The typical microminerals (main grains less than 5 µm in size) in 7 kimberlite tubes of Yakutiya (Nachalnaya, Novinka-1, 2, 4, Vodorazdelnaya, Obnazhennaya, Sytykanskaya) were studied in details under scanning electron microscope. The objects of investigations are included as the microminerals in large crystals, binding substance, and the kimberlites alteration products. The characteristic differences in chemical composition of indicative components (intermetals, sulfides, silicates, etc.) are revealed that may be used for evaluation of diamondiferousness of kimberlites |
