Platinum-group element contents of Karelian kimberlites: implications for the PGE budget of the sub-continental lithospheric mantle [PDF]
, 2017 We present high-precision isotope dilution data for Os, Ir, Ru, Pt, Pd and Re in Group I and Group II kimberlites from the Karelian craton, as well as 2 samples of the Premier Group I kimberlite pipe from the Kaapvaal craton. The samples have, on average,

Geological and structural characteristics of deep-level rock mass of the Udachnaya pipe deposit
Записки Горного института, 2021 For hard rock massifs, structural disturbance is a key indicator of mining structure stability. The presence of intersecting structural elements in the massif reduces rock strength and leads to formation of potential collapse structures.

Archaean and Proterozoic diamond growth from contrasting styles of large-scale magmatism [PDF]
, 2017 Precise dating of diamond growth is required to understand the interior workings of the early Earth and the deep carbon cycle. Here we report Sm-Nd isotope data from 26 individual garnet inclusions from 26 harzburgitic diamonds from Venetia, South Africa.
