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 |
| Аннотация |
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. |
