Twinning is a phenomenon in mineralogy whereby a single crystal of a mineral has two or more parts in which the crystal lattice is differently orientated. The shared surface between two twins is called the composition or twin plane, and the orientation to either other is determined by symmetry through rotation or reflection; this relationship …[Read More]
In my opinion, there aren’t many finer ways to spend an autumnal afternoon than ambling round the historical suburb of Clifton in Bristol. Bounded to the west by the dramatic limestone cliffs of the Avon Gorge and the bucolic open downs of Clifton and Durdham, Clifton Village is a Bristol rarity, in only having been …[Read More]
Today we have a guest post from Dr. Peter Tomiak who delves into the life and death of corals… I completed my undergraduate degree in Biology and Geology at the University of Bristol in 2008. Subsequently I undertook a sponsored internship with Save The Elephants, in Samburu National Park Kenya, before starting a short term position alongside Prof. Adrian Lister …[Read More]
KT Cooper is a PhD student in the School of Earth Sciences at the University of Bristol. A carbonate geochemist by training, she has just returned from a three-month secondment to Houston, Texas, USA working with Exxon Mobil. The world of microbiology is weird, wonderful and also quite multi-colourful. Purple bacteria, a particular hue of microbe …[Read More]
Sorcha McMahon is a third year PhD student in the School of Earth Sciences at the University of Bristol. Sorcha is investigating how strange igneous rocks called carbonatites may have formed, using both natural samples and high-pressure experiments. As part of my undergraduate MSci course at the University of Cambridge, I carried out a project …[Read More]
Lying just under the Earth’s surface, the East African Rift is a region rich in geothermal resources. Exploitation of this clean and green energy source is steadily been gaining momentum. What is the geological mix that makes the Rift Valley ripe for geothermal power and how is it being tapped? The East African Rift, stretching …[Read More]
On finding out my ‘profession’, there’s one fact that people proudly announce to me on a regular basis: “I know the three rock types: sedimentary, igneous and metamorphic!”. What usually emerges from deeper probing is that most people are comfortable with the concept of sediments and magma, but metamorphism is a bit of an enigma. …[Read More]
Mel Auker is an Earth Sciences PhD student in the School of Earth Sciences at the University of Bristol. A mathematician by trade, Mel’s PhD uses numerical approaches to better understand past, present, and future global volcanic hazard and risk. You might remember Charly’s “Fifity Shades of Grey” post, highlighting the colourful spectrum of rocks; …[Read More]
KT Cooper is a PhD student in the School of Earth Sciences at the University of Bristol. A carbonate geochemist by training, she is currently on a three-month secondment to Houston, Texas, USA working with Exxon Mobil. Not all research is successful and not all experiments have a positive outcome or even the outcome you first …[Read More]
Mel Auker is a PhD student in the School of Earth Sciences at the University of Bristol and is a regular contributor to Between a rock and hard place. In her own words, she’s an “applied mathematician bumbling my way through a geology PhD”. Here she provides us all with some Monday afternoon inspiration. Read …[Read More]
