Layers of the Earth

Well, this is going to be stuck in my head all day.

9800 Feet

We got to Kidd Creek mine at 6:45 am. As we entered the mine site, we passed a billboard proudly announcing that it had been 15 days since the last accident, and someone in our group joked that 15 days wasn’t much to brag about. We laughed, a little nervous but excited at the prospect of entering one of the world’s deepest mines, to study the underground geology of the Canadian shield.

Agouron Photo Album

I lieu of detailed blog posts covering the rest of my Agouron trip, I’ll let these pictures do the talking (along with my annotations).

Agouron Day 2: Greenstone Belts 101

On the second day of the Agouron field trip, we piled into the vans and drove out of town, down some rather rugged road (especially for minivans!) and parked next to waste rock from an old mine. But instead of investigating this rock, we set off into the swamp on the other side of the road. After a muggy walk through tailings-stained swamp and tall cattails, along a beaver dam, and than up a rise into the forest, we came to a clearing under some power lines where rocks were exposed.

Agouron Day 1: Introduction and Kam Kotia Mine Tailings

The Kam Kotia mine site is famous for being an environmental disaster. Mines tend to dump their ground-up waste rock into a reservoir nearby, typically a lake, where the finely ground rocks rapidly alter leading to nasty acidic chemicals that tend to make the area uninhabitable for a while. The Kam Kotia tailings have been partially “reclaimed” but the area is still pretty devastated.

Agouron Geobiology Field School!

Greetings from scenic Timmins Ontario! I will be spending the next 9 days with a bunch of geologists, biologists, chemists, planetary scientists, and all around smart people, learning about the geology of the Abitibi Greenstone Belt near Timmins. In particular, we will be talking a lot about the origin of life, and how this chunk of ancient crust on Earth can (or cannot) be used as an analog for Mars …

MarsSed 2010 Field Trip Day 2: Stromatolites, Gypsum and Layers

We started off Day 2 of the field trip by driving up onto the eroded rocks of what used to be the tidal flats of the ancient reef, between the shore and the continental shelf. The closest modern-day analog to the rocks that we visited is the Persian Gulf, where you have an arid climate and deposition on the shelf and down into the deeper ocean basin. In the tidal …
