| Реферат: | eng: The factual evidence and the evidence of experimental studies support a cumulative origin of dunites from alkali-ultrabasic complexes of the Siberian Craton (Guli, Kondyor, Inagli, and others). These rocks formed during deep igneous evolution of melts that are close to biotite-pyroxene alkali picrite (meimechite). Olivinites that sometimes compose completely or in part the particular massifs (Bor-Yuryakh, Odikhincha, Kugda, and others) formed, in turn, due to recrystallization of dunites under the effect of alkali melts and fluids. This insight into the origin of dunites and olivines from these intrusive complexes requires an objective assessment of their ore-bearing potential. © 2012 Pleiades Publishing, Ltd.
