Geochemical properties and transformation of the microelement composition of soils during the development of primary diamond deposits in Yakutia

open access: yesЗаписки Горного института, 2023
Extraction of diamonds from primary deposits in Siberia is associated with the development of kimberlite pipes in challenging environmental conditions, accompanied by a complex impact on the environment. The article presents the results of monitoring the

Experiences of Legal Pluralism in Sierra Leone: Land Governance, Neoliberal Dispossession and Gender (In)justice

open access: yesDevelopment and Change, Volume 57, Issue 2, Page 315-338, March 2026.
ABSTRACT Sierra Leone's land governance reform policies are often based on the neoliberal assumption that market growth, gender equality and women's empowerment are mutually compatible objectives. Contrary to this assumption, this article argues that while market‐oriented reforms can help to destabilize legal and cultural norms that are discriminatory ...

Geochemical criteria for identifying diamond-bearing areas [PDF]

open access: yesE3S Web of Conferences
The paper demonstrates that diamondiferous objects may be pinpointed even by the middle-scale geochemical surveys. Relevant criteria were developed to identify and classify such objects by their prospectivity.

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

open access: yesJournal 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

open access: yesJournal 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 ...

Characteristics of the Deep Structure of the Kimberlite-Controlling Faults of the Arkhangelsk Diamondiferous Province According to the Microseismic Sounding Method. Review

open access: yesRussian Journal of Earth Sciences
Prospecting for kimberlite pipes can be challenging due to their small size in plan. One potential solution to this problem is to search for kimberlite-controlling faults.
