N.G. Barnov, V.V. Shchiptsov. A summary overview of deposits and large occurences of noble precambrian corundum in the world // Transactions of Karelian Research Centre of Russian Academy of Science. No 10. Precambrian Geology Series. 2021. Pp. 78-87

Keywords: noble corundum; ruby; sapphire; deposit; Precambrian; metamorphism

The paper is a summary review of the deposits and occurrences of noble corundum in Precambrian ore regions of the world. The ore bodies of ruby and sapphire deposits are divided into two groups. The first group comprises magmatic, pegmatite, and metasomatic deposits, mainly of Phanerozoic age. The second group is mainly represented by Precambrian formations. The article considers the formation of noble corundum associated with Precambrian complexes within the borders of provinces, belts and ore regions, and provides a brief description of corundum-bearing complexes in the Precambrian from Neoarchean to Neoproterozoic, with references to the respective deposits or occurrences. We indicate the P-T setup for metamorphism during the formation of corundum deposits from Precambrian corundum-bearing metamorphic complexes aged from 2.7–2.8 Ga to 610 Ma.
