Following kimberlite indicator minerals to source in the Chidliak Kimberlite Province, Nunavut

, 2013
The discovery of diamond-bearing kimberlite within the Chidliak kimberlite province on Hall Peninsula, southern Baffin Island, Nunavut, is a classic example of the application of traditional diamond-exploration techniques in a glaciated terrain. To date,

Predicted relative kimberlite potential.

, 2022
A-D/ Global relative kimberlite potential maps for lithosphere thicker than 150 km from 320 Ma (A-B) and from 640 Ma (C-D) for tomographic model S40RTS (A, C) and Case 2 (B, D). Kimberlites from ref. [22] are shown as black circles for the last 320 Ma (A-

Full‐Waveform Seismic Tomography of the Upper Mantle Beneath the Arabia‐Eurasia Collision Zone

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Despite being one of the most recent major orogenic events, the timing of the Arabia‐Eurasia collision is still debated. Much of the discrepancy arises due to uncertainties over the amount of continental subduction of the Arabian passive margin and the timing of a hard collision of cratonic Arabian lithosphere with Eurasia.

Investigating Layered Cratonic Lithosphere in the Fennoscandian Shield

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Cold, thick, and chemically depleted lithosphere with high seismic velocity and low attenuation characterizes continental cratons. However, discrepancies between xenolith‐based thermal constraints and those inferred from surface‐wave seismic models, together with the widespread observation of mid‐lithosphere discontinuities, challenge the ...

Petrogenetic processes in the ultramafic, alkaline and carbonatitic magmatism in the Kola Alkaline Province: a review [PDF]

, 2005
Igneous rocks of the Devonian Kola Alkaline Carbonatite Province (KACP) in NW Russia and eastern Finland can be classified into four groups: (a) primitive mantle-derived silica-undersaturated silicate magmas; (b) evolved alkaline and nepheline syenites; (
