Genesis and evolution of kimberlites
Kimberlites are volcanic rocks enriched in CO2 and H2O and derive from the deepest-
sourced melts (up to 300 km) that reach Earth's surface. The mantle processes that generate …

[HTML][HTML] Subducted carbonates not required: Deep mantle melting explains stable Ca isotopes in kimberlite magmas
Ca isotope geochemistry has great potential for improving our understanding of magmatic
systems and for tracing the deep Earth carbon cycle. There are still many open questions …

The stable isotope character of the Earth's mantle–A review
This review describes the stable isotope character of the Earth's mantle, the 2900 km thick
silicate layer between the core and crust that comprises 67% of the Earth's mass and 84% of …

Geodynamic and isotopic constraints on the genesis of kimberlites, lamproites and related magmas from the Finnish segment of the Karelian craton
Despite the scientific and economic significance of kimberlites and related magmas, their
origin is unclear. Here, we address this issue using whole‐rock and perovskite‐derived Sr …
