Реферат:	eng: Behavior of kimberlite indicator minerals in glacial settings based on the study of dispersion halo of Pipe CL-25 in the Slave Craton (Canada) is discussed. The compliance of the dispersion halo with the standard object was substantiated for studying the behavior of indicator minerals in glacial settings. The studies showed that ice-rafted indicator minerals did not virtually change at a distance of tens of kilometers; i.e., the minerals are not crushed, rounded, and subjected to physicochemical alterations. Their dispersion is determined by the direction of glacier motion. The results of the studies were compared with the published data, which indicate intense mechanical erosion of minerals under subaquatic conditions related to a glacier, particularly in the central Timan Range. These data are most likely erroneous and related to an incorrect choice of the standard object for studying: Minerals described in these works are derived from old intermediate reservoirs reworked by a glacier, and the mentioned changes in minerals are related to the preglacial stage. © 2010 Pleiades Publishing, Ltd.
