Continental Basalts and Mantle Xenoliths
Eos, Transactions American Geophysical Union, 1985 In this decade of the International Lithosphere Program, much scientific attention is being directed toward the deep continental crust and subadjacent mantle. The petrologic, geochemical, and isotopic signatures of basaltic magmas, which transect much of the lithosphere as they ascend from their site of melting, and of contained cognate and accidental ...

The Moho as a magnetic boundary [PDF]
Magnetic data are presented for mantle derived rocks: peridtites from St. Pauls rocks, dunite xenoliths from the kaupulehu flow in Hawaii, as well as peridolite, dunite and eclogite xenoliths from Roberts Victor, Dutoitspan, Kilbourne Hole, and San ...

Geophysical Research LettersThe temperature of the convecting mantle and thickness of the lithosphere control many of Earth's processes. However, there is disagreement regarding the evolution of these quantities through time.

Allanite in Mantle Eclogite Xenoliths
Journal of PetrologyAbstract Rare-Earth Elements (REE) are key geochemical tracers of crust–mantle differentiation, but there are few direct data on REE-rich minerals in mantle rocks. Here, we report the combined petrography and comprehensive chemical and isotopic characterization of three coesite- and kyanite-bearing eclogite xenoliths from the Udachnaya ...

Evolution of the Lithospheric Mantle beneath the Marsabit Volcanic Field (Northern Kenya): Constraints from Textural, P-T and Geochemical Studies on Xenoliths [PDF]
, 2017 Xenoliths hosted by Quaternary basanites and alkali basalts from Marsabit (northern Kenya) represent fragments of Proterozoic lithospheric mantle thinned and chemically modified during rifting in the Mesozoic (Anza Graben) and in the Tertiary-Quaternary (

A study of ex-situ carbon mineralization under low intensity aqueous reaction
Carbon Capture Science & TechnologySafe, scalable and permanent options for carbon dioxide storage is essential to achieve net negative greenhouse gas emissions and limit catastrophic global warming. A benign and thermodynamically stable form of CO2 storage is a carbonate mineral.
