PhD reflections: Sorcha

Between a Rock and a Hard Place began as an Earth Science PhD blog in February 2013, as a place to ramble on about PhD life and general science topics. Almost two years later, some of the contributors have finished, others have submitted, and the rest are nearing the end.  Over the next few weeks, the BaR contributors […]

The waterfall drops from the summit of the largest tepui (table-top mountain) of the Guiana Highlands of South America, Auyantepui, […]

Science Snap #21: Nash Point, Vale of Glamorgan, Wales

Originally posted on the EGU blog network Nash Point is a picturesque headland along the coastline of the Vale of Glamorgan, consisting of near-vertical cliffs of limestone and mudstone. Strata are of Blue Lias age, and at low tide the exposed shore platform reveals indicative fossils including tiny ammonites.

It consists of successive city foundations and temples constructed by the kings of three dynasties over a period of about 600 years. The site is most famous […]

Using garnet geochemistry to investigate the lithospheric mantle beneath northern Tanzania

Originally posted on the EGU blog network As part of my undergraduate MSci course at the University of Cambridge, I carried out a project investigating a collection of thin sections from peridotite xenoliths from northern Tanzania. The main aim of this research was to constrain the petrogenetic evolution of the lithospheric mantle beneath the East […]

Originally posted on the EGU blog network Following on from Mel Auker’s report on her visit to Japan for the The IAVCEI Scientific Assembly, Kate and Sorcha tell us about their recent trip to Florence for Goldschmidt 2013. What? The annual Goldschmidt conference is a major geochemistry conference, alternating between Europe and North America each year. […]

Science Snap (6): SEM images of a high-pressure experiment

Originally posted on the EGU blog network These back-scattered electron (BSE) images are a typical view of one of the high-pressure experiments that I run on the piston-cylinder apparatus, here in the BEEST labs at the University of Bristol. Such photographs are taken using the Scanning Electron Microscope (SEM), and are an essential stage in […]
