Abstract
The present paper discusses the results of a systematic study of mica microcrystals of the phlogopite-kinoshitalite group found in the main body of the Yakut kimberlite province, by the example of mid-Palaeozoic pipes of the Khompu-May kimberlite field in Central Yakutia. Сhemical composition and zone distribution of minerals are reported, a comparison is provided with mica, peridotite mantle xenoliths from the kimberlite pipes of Africa, single kimberlite bodies of Canada, Africa, USA, China, and Yakutian kimberlite province, carbonatite massifs of Brazil, and melilitites of Russia. The following mica types were identified: phlogopite, barium-bearing phlogopite, barian phlogopite, and potassium kinoshitalite. All these types can be found within one grain, defining its zone distribution. The late-stage magmatic character of the mica under investigation was specified, with its composition being caused by barium-rich fluids. Investigation of zoning in flakes allowed us to describe the behavior of BaO in kimberlite formation of the pipes. Similarities and differences in the composition of mica from the Khompu-May kimberlite pipes and kimberlite bodies studied earlier, carbonatites, mantle xenoliths, and melilitites indicate that the mineral is specific for different magmatic systems with barium-rich fluids. Thus, mica composition can be used for comparative studies of kimberlites and other alkaline ultrabasic rocks.
