Chromitite deposits of Ufaley ultramafic massif (South Urals)

open access: yesGeoresursy, 2022
Data on the morphology, composition, textural and structural features of chromite deposits of the Ufaley ultramafic massif are presented. The mineralogical and compositional features of the host ultramafic rocks allow us to interpret them as depleted restite from partial melting of mantle peridotites.

Volcanic Forcing Overwhelmed AMV's Influence on Eurasian Winter Temperatures During the Little Ice Age

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The warm phase of Atlantic Multidecadal Variability (AMV) induces winter cooling in central Eurasia and widespread warming elsewhere during the instrumental period. To overcome the limitation imposed by short length of instrumental records in studying multidecadal climate variability, in this study, we examine changes in AMV teleconnections ...

GENETIC DIVERSITY OF SIBERIAN STONE PINE UNDER INTRODUCTION IN THE SOUTH URALS AND BASHKIR CIS-URALS

open access: yesСибирский лесной журнал, 2016
Allozyme polymorphism of Siberian stone pine Pinus sibirica Du Tour has been studied in 14 artificial stands in the South Urals and Bashkir Cis-Urals on the base of 7 gene-enzyme system analysis. The following values of genetic diversity are determined: mean number of alleles per locus (A) constitutes 1.69±0.08; portion of polymorphic loci (P95) – 50.0
