The 15th photo of the week is of an area of natural acid rock drainage (ARD) in Eagle Plains, Yukon. ARD is a phenomenon that most people associate with mine tailings and mine waste. However, it occurs naturally as well since the only criteria that need to be met are a source of oxidized water, such as rain, rocks or minerals that have a high sulphur content, and a very little carbonate in the roc ...[Read More]
Geology Photo of the Week #14 – Dec 2-8
This week’s photo, which is posted mid-week instead of at the beginning is one that I only took this Monday. I was away all day at the Royal Military College SLOWPOKE-2 reactor doing some neutron activation of cesium and calcium. We were making minute quantities of Cs-134 and Ca-41 for research purposes on the accelerator mass spectrometer. This photo is one that I was able to take while we ...[Read More]
Guest Post – Things go up, things go down – Dr. Martin Wolstencroft
This post is the first of hopefully many guest posts by graduate students and geologists I work with. This post is by Dr. Martin Wolstencroft, a post doctoral fellow with Dr. Glenn Milne here at UOttawa. Martin is a geophysicist by trade and hails from a small town in central England. He did his undergraduate degree and PhD. at Cardiff University in Wales. His PhD. research focussed on the solid E ...[Read More]
Geology Photo of the Week #13 – Nov 25-Dec 1
So the 13th photo of the week is this sweet as pic of boiling mud from New Zealand’s North Island. Both photos were taken by me in July of 2009. I had to stand at the ready for quite a while to try and get good pictures of the bubbles bursting and there were many failed attempts. On the whole I think I did pretty well. Hope you like them! By the way, stay tuned for some an awesome guest post ...[Read More]
The 46th Ottawa Gem and Mineral Show
A few weeks ago I went to the 46th annual Ottawa Gem and Mineral show. I have always been a dedicated mineral and fossil collector and shows like this allow me to indulge my inner collector and drool over all the fantastic specimens. I have been to a lot of shows, all local such as Kingston, Peterborough and now the Ottawa show, but there are tons all over the world. In fact, I would speculate tha ...[Read More]
It’s all about scales
It has often been said that geology is the study of scales. Time scales, large scales, small scales and many others. Indeed, one of the most crucial parts of any photo or map is the scale. Furthermore, geologic concepts can be applied from the planet scale to the atomic scale and every size in between. What confuses most people though is not only do we work in terms of huge size/magnitude variatio ...[Read More]
Geology Photo of the Week # 12 – Nov 18-24
Check out this beauty! AMAZING. Those crystals are a few centimetres in size, flawless and have a great colour. Unfortunately, I don’t remember where it came from. I know, I know, this is the cardinal sin, so I apologize for that. I hope you enjoy looking at it all the same. Cheers, Matt
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]
A GeoPoetry Anthology – Accretionary Wedge #51 Compilation
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]
Geology Photo of the Week # 10 – Nov 4-10 – A Mysterious Monster!
I apologize for the delay posting this. I was in Washington DC earlier this week to take in a Supreme Court hearing that never actually happened due to Hurricane Sandy. My flight out was also delayed and thus many other things in my life are delayed right now including this post. This photo poses a bit of a conundrum…since I don’t have a clue what it is! I have an idea, but I’d l ...[Read More]
