A method for controlling siltation of water catchments of district drainage systems of kimberlite mines

Записки Горного института, 2018
High contamination of mine water leads to intensive siltation of water catchments of district water drainage installations of kimberlite mines in Russia, because of which their pumping equipment periodically works in non-stationary regimes. At present, a

East Meets West: The Trace of the Mesoproterozoic Kibaran Event in the Mantle Lithosphere Beneath Eastern Tanzania

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract We present elemental geochemistry and multiple isotopic systematics (Re‐Os, Lu‐Hf, Sm‐Nd and Sr) for mantle peridotite xenoliths from Lashaine in northern Tanzania. We use the data to examine how the major Proterozoic tectono‐thermal events that affected the crust of the western Tanzanian craton are imprinted on the lithospheric mantle in the ...

Electrical Conductivity of Carbonatite Melts to 20 GPa: Constraints on Partial Melting Atop the 410‐km Discontinuity and in the Lower Mantle Transition Zone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Deep‐origin carbonatite melts are considered to be the products of partial‐melting of the oceanic crust in the subduction zones. In this study, we conducted electrical conductivity (EC) measurements on two samples, the composition of which resemble the partial‐melting products atop the 410‐km discontinuity and in the lower part of the ...

Enhanced weathering of kimberlite residues in a field experiment: implications for carbon removal quantification and mine waste valorization

Frontiers in Climate
Scaling up enhanced rock weathering (ERW) will require gigatonnes of suitable rock, which could include mine wastes such as the estimated 3.9 Gt of kimberlite residues from historic diamond mining.

Mineral-PET: Kimberlite sorting by nuclear-medical technology [PDF]

, 2010
A revolutionary new technology for diamond bearing rock sorting which has its roots in medical-nuclear physics has been taken through a substantial part of the R&D phase. This has led to the construction of the technology demonstrator.

Revealing the Magmatic Impulse Emplacement and Evolution Path of Kimberlite in Southern Liaoning through Mineralogical Characteristics of the Phlogopite Zone

Applied Sciences
Phlogopite is a crucial indicator for effectively constraining the magmatic evolution and emplacement mechanism of kimberlite. In this study, samples were collected from the No. 110 kimberlite pipe within diamond belt I and the No.

The effect of temperature and pressure on the distribution of iron group elements between metal and olivine phases in the process of differentiation of protoplanetary material [PDF]

The distribution patterns of Ni, Co, Mn, and Cr were studied in olivines of various origins: from meteorites (chondrites, achondrites, pallasites), which are likely analogs of the protoplanetary material, to peridotite inclusions in kimberlite pipes ...
