Bibliographic description in the original language

V. F. Sotnikova, R. Kh. Sungatullin, and E. V. Kislov First Mineralogical and Geochemical Data on Placer Nephrite of the Vitim Highlands, Republic of Buryatia // Lithology and Mineral Resources. 2025. Vol. 60, No. 3, pp. 333-345. DOI: 10.1134/S0024490225700038

Annotation

The material composition of placer (alluvial) dolomite-type nephrite from the Tsipa River in the nephrite-bearing region of the Vitim Highland has been examined. Initial data on the mineral composition of both inner and outer zones of the alluvial dolomite-type nephrite pebbles have been obtained. Placer neph rite is characterized by an inherited staining rim, a small amount of accessory minerals, fine-grained texture, randomly fibrous structure, and elevated alkali content. Chemical composition features of the staining rim formed under exogenous conditions include the development of Mn–Fe hydroxides, with a significant increase in the Fe3+ content and elevated levels of Co and Ba. A genetic relationship has been established between the placer nephrite and its primary source (nephrite from the Kavokta deposit). Comparison between primary and placer dolomite-type nephrite promoted the identification of diagnostic characteristics for conducting expert assessments.
