Characteristics of the Deep Structure of the Kimberlite-Controlling Faults of the Arkhangelsk Diamondiferous Province According to the Microseismic Sounding Method. Review

Russian Journal of Earth Sciences
Prospecting for kimberlite pipes can be challenging due to their small size in plan. One potential solution to this problem is to search for kimberlite-controlling faults.

Mantle xenoliths from Komsomolskaya kimberlite pipe, Yakutia: Multistage metasomatism

Geosystems and Geoenvironment
Minerals from > 200 mantle xenoliths from Komsomolskaya kimberlite pipe were studied by electron microprobe and LA-ICP-MS. They are metasomatised garnet and spinel peridotites containing phlogopite, amphibole and ilmenite with garnets (up to 12.5 wt ...
