Primordial neon and the deep mantle origin of kimberlites [PDF]
Nature CommunicationsThe genesis of kimberlites is unclear despite the economic and scientific interest surrounding these diamond-bearing magmas. One critical question is whether they tap ancient, deep mantle domains or the shallow convecting mantle with partial melting ...

Diamond preservation in the lithospheric mantle recorded by olivine in kimberlites [PDF]
Nature Communications, 2023 The diamond potential of kimberlites is difficult to assess due to several mantle and magmatic processes affecting diamond content. Traditionally, initial evaluations are based on the compositions of mantle-derived minerals (garnet, chromite ...

Kimberlite eruptions driven by slab flux and subduction angle [PDF]
Scientific Reports, 2023 Kimberlites are sourced from thermochemical upwellings which can transport diamonds to the surface of the crust. The majority of kimberlites preserved at the Earth’s surface erupted between 250 and 50 million years ago, and have been attributed to ...

Mapping global kimberlite potential from reconstructions of mantle flow over the past billion years. [PDF]
PLoS ONE, 2022 Kimberlites are the primary source of economic grade diamonds. Their geologically rapid eruptions preferentially occur near or through thick and ancient continental lithosphere.

Alkaline lamprophyres from the Sokli complex, northern Finland [PDF]
Bulletin of the Geological Society of Finland, 1978 Alkaline lamprophyric dykes in the Sokli carbonatite complex closely resemble kimberlites in mineralogical and chemical composition. Mineralogically, they differ from kimberlites by the presence of high-manganese ilmenite and richterite, and the absence ...

Аbout use of ancient weathering crusts formation during diamond-prospecting works
Мінеральні ресурси України, 2021 Complex research of Late Devonian – Early Carboniferous and Middle-Late Triassic weathering crusts on various rocks (terrigenous-carbonate formations, dolerites, tuffs, tuffaceous formations and kimberlites) indicated that in conditions of warm and humid

The Relationship Between Kimberlitic Magmatism and Electrical Conductivity Anomalies in the Mantle
Geophysical Research Letters, 2022 Kimberlites are igneous rocks whose formation remains enigmatic due to their severely altered nature, highly variable compositions and rapid ascent through the lithosphere.
