Deep Earth volatile cycles as revealed by basalt chemistry
… a regulator on our planet’s long term climate. Basalt geochemistry is our most direct probe of Earth’s convecting mantle, however the tendency of volatile elements to form vapour phases deep within volcanic systems obscures the mantle volatile signals inherited by basalts. This thesis explores …

Continental Magmatism and Dynamic Topography
… spinel-garnet transition zone. Rare tholeiitic basalts record temperatures up to 1360$^{\circ}$C. Analysis of global and regional shear wave velocity models closely matches these results. The principal control on continental magmatism appears to be temperature anomalies within the upper mantle …
