European Geosciences Union General Assembly 2015 - Garnet Classification
Geological setting of Grib kimberlite
The Arkhangelsk province is situated in the
north part of East European craton.
Several fields of kimberlites and related
magmatism were distinguished within the
province;
The Grib pipe is located in the central part
of the Arkhangelsk province
(Chernoozerskoe field);
It is classical kimberlite pipe like as South
Africa group 1 kimberlite pipe [Mitchell,
1995];
The kimberlite age is 374 ± 1.3 Ma (Rb-Sr
isotope methods by phlogopite)
[Lebedeva et al., 2014].
