Preprint
The Earth’s mantle holds more carbon than its oceans, atmosphere and continents combined, yet the distribution of carbon within the mantle remains uncertain. Global variations in the carbon content of the depleted mantle have been inferred from carbon-trace element systematics of ultra-depleted mid-ocean ridge glasses and melt inclusions, though th...
Article
The architecture of magmatic plumbing systems and the behaviour of the crystal mush underlying active volcanoes can be assessed by examining the crystal chemistry and microstructure preserved in solidified magma bodies, i.e. dykes, sills, and layered intrusions. Combining field and petrographic observations of the Little Minch Sill Complex in Scotl...

Our present understanding of the mantle carbon budget is in part built upon measurements of carbon concentrations in olivine hosted melt inclusions. Only a small number of such datasets are thought to have avoided degassing, having been entrapped prior to CO2 vapour saturation, and are therefore able to constrain primary CO2 concentrations. The abs...

New crystallisation temperatures for four eruptions from the Northern Volcanic Zone of Iceland are determined using olivine-spinel aluminum exchange thermometry. Differences in the olivine crystallisation temperatures between these eruptions are consistent with variable extents of cooling during fractional crystallisation. However, the crystallisat...

Continental rifting is often associated with extensive magmatic activity, emplacing millions of cubic kilometres of basalt and triggering environmental change. The lasting geological record of this volcanic catastrophism are the large igneous provinces found at the margins of many continents and abrupt extinctions in the fossil record, most strikin...
