Over the last century, geoscientists have made incredible contributions to our understanding of the Earth, the solar system, and beyond. Inspired by the American Geophysical Union (AGU) and the International Union of Geodesy and Geophysics (IUGG) centennials, which are celebrated in 2019, we would like to highlight Europe’s role in shaping the geosciences and the great achievements of European geo ...[Read More]

Geology Photo of the Week #46
This week’s photo brings us back to the world of geochemistry. I don’t have much information on this photo beyond that it was taken in Italy. However, if I may speculate a little it looks like these crystals may possibly be volcanic in origin and the fact that it was taken in Italy, which is famous for its volcanic sulphur deposits. I say this because such crystals are often found nea ...[Read More]
Thaw Slumps of the NWT
I recently across an article that reminded me of my field work days in the early stages of my PhD in the Canadian Arctic at retrogressive thaw slumps. The article discusses the impending catastrophic drainage of a lake when the thin strip of land separating it from a thaw slump fails (see article), which it will inevitably do very soon. The story has now been picked up all across Canada in the con ...[Read More]
AW# 60 – Radioactivity: What’s the use?
I am very excited to be hosting the 60th Accretionary Wedge at GeoSphere! Sorry my own contribution is so slow in coming…it has been a busy month PhD wise. In fact, I expect it will be a busy year PhD wise since I am hoping to submit in the Fall of 2014 and I have got a LOT of writing to do. Anyway, in the call for posts I said: For this wedge the topic will be momentous discoveries in geolo ...[Read More]
Geology Photo of the Week # 21
The photo of the week today is of a Canadian National Heritage Site. It is located just outside of Dawson City, Yukon and is unassumingly called Dredge 4. Those of you who read this blog regularly will know that I am a huge fan of the Yukon, which is the site of my field work, and love talking about the gold rush history of the region. Very few things embody this history better than Dredge 4̷ ...[Read More]
Geology Photo of the Week # 11 – Nov 11- 17
The Photo of the Week #11 is of a superb cave decoration from Kelly Hill caves located on Kangaroo Island, South Australia. I was there in 2009. Most cave decorations are draped against the wall of the cave. More rarely stalactites, stalagmites and other free hanging features form. These are usually perpendicular to the cave floor or ceiling much like icicles. However, even more rarely, odd shape ...[Read More]
