Xenolith Constraints on the Mantle Potential Temperature and Thickness of Cratonic Roots Through Time

Geophysical Research Letters
The 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.

A study of ex-situ carbon mineralization under low intensity aqueous reaction

Carbon Capture Science & Technology
Safe, 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.

Modes of Occurrence of Spinel in Xenoliths.,

The Journal of the Geological Society of Japan, 1949
During his petrological study on the inclusions in the garnet-biotite-andesite from Nijo Volcano near Osaka, the present writer pointed out the common occurrence of spinel associating intimately with porphyroblastic andalusite or sillimanite in some xenoliths derived from argillaceous metamorphic rock, as the feature to be observed in xenoliths when ...

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 ...
