Guest Post: Solar Storms and the Earth’s Protective Shield – Laura Roberts Artal
I am a PhD student at the University of Liverpool Geomagnetism Laboratory. My current research project is the palaeomagentic study of 3.5-3.2 billion year old rocks from South Africa. The aim of my research is to improve our understanding of the long term evolution of the Earth and the surface conditions under which the first forms of life originated through using palaeomagnetic records. The rock ...[Read More]

Imaggeo on Mondays: Metamorphosis
This fold is part of the metamorphic core of the Pyrenees. The shear zone is almost vertical, producing a small parasitic fold (a smaller fold within a larger one), which looks almost as if it continues into the sky. The metamorphic sediments are about 500 million years old and have been deformed several times, most recently during the alpine orogeny. The alpine orogeny was period of extensive mou ...[Read More]

There is something very frightening about a substance that shoots off invisible rays that can kill you if you’re exposed to enough of them. However, most people really don’t need to worry about be ...[Read More]

Nothing better characterises the wild US West than endless landscapes of red hoodoos, spires of rock protruding from the bottom of an arid drainage basin or badland. Found mainly in desert and dry, hot areas, hoodoos are distinctive from similarly-shaped formations, such as spires or pinnacles, because their profiles vary in thickness throughout their length. Their distinctive colour bands are the ...[Read More]

Guest Lecture – Dr. Tim Lowenstein
Our department was recently lucky enough to have Dr. Tim Lowenstein from SUNY Binghamton come give a guest lecture on the changes in the chemistry of seawater throughout geologic time. Originally, we thought that the major ion chemistry in the past was more or less the same as it is today. However, over the last 10 years this long standing belief has been challenged by many researchers and champio ...[Read More]

Firstly, I would like to thank everyone that participated in this edition of the Accretionary Wedge. There were a few comments that the topic was somewhat out of people’s comfort zone so I am glad that there was still fantastic participation and people willing to try poetry writing out even if it was a different sort of medium. As you know poems come in all shapes, sizes and subjects and a k ...[Read More]
