Discussion of "Kimberlites and aillikites as probes of the continental lithospheric mantle", by D. Francis and M. Patterson (Lithos v. 109, p. 72-80)

Lithos, 2010
Abstract The origin of kimberlites and volatile-rich alkaline ultramafic magmas such as aillikites has been a matter of considerable scientific interest and the recent paper by Francis and Patterson (Francis and Patterson, 2009. Kimberlites and Aillikites as probes of the continental lithospheric mantle.

U–PB (ID-TIMS) AGE OF GARNET FROM AILLIKITES OF KOLA ALKALINE PROVINCE

Доклады Российской академии наук. Науки о Земле, 2023
U–Pb (ID-TIMS) geochronological studies of garnet from aillikites of the Kandalaksha dyke swarm (Kola alkaline province) were carried out. The obtained estimate of the U–Pb age of the garnet (374 ± 3 MA) coincides with the interval (373–377 MA) of the main stage of alkaline magmatism of the Kola province (LIP).

Crystallisation of mela-aillikites of the Narsaq region, Gardar alkaline province, south Greenland and relationships to other aillikitic–carbonatitic associations in the province

Lithos, 2006
Abstract Aillikites (carbonated, melilite-free ultramafic lamprophyres grading to carbonatites) are minor components of the Gardar alkaline igneous province. They occur principally as minor intrusions and as clasts in diatremes, but more voluminous aillikitic intrusions crop out near the Ilimaussaq Complex, which they predate by a few million years ...

Age and petrogenesis of ultramafic lamprophyres of the Arbarastakh alkaline-carbonatite complex, Aldan-Stanovoy shield, South of Siberian Craton (Russia): evidence for ultramafic lamprophyre-carbonatite link

Journal of Petrology, 2022
In this study, we discuss mineral chemistry data, melt inclusion study results, and report Ar-Ar phlogopite age for the aillikite dykes of the Arbarastakh alkaline-carbonatite complex on the Aldan-Stanovoy shield, Russia.

Ultramafic xenoliths from aillikites in the Tarim large igneous province: Implications for Alaskan-type affinity and role of subduction

Lithos, 2021
Abstract The Tarim large igneous province (TLIP) located in northwestern China is characterized by a relatively long duration of magmatism and complex lithology as compared to other global LIPs. Previous studies correlated these features to the interaction between mantle plume and subducted slab. However, no direct subduction-related magmatic records

Olivine from aillikites in the Tarim large igneous province as a window into mantle metasomatism and multi-stage magma evolution

American Mineralogist, 2021
Abstract Aillikites are carbonate-rich ultramafic lamprophyres, and although they are volumetrically minor components of large igneous province (LIP), these rocks provide important clues to melting and meta-somatism in the deep mantle domain during the initial stages of LIPs.
