Today, I went to Quincy Mine for my geology orientation class! It was an awesome trip!
Like I mentioned in my last post, the Keweenaw is notable for its copper and mining is really what built most of these towns around here. Quincy Mine is a well known one of these mines, and a mine that MTU has done a lot of research in! The old classroom picture was one of the rooms they taught in.
This mine is a good place to check out the geology of the area. We passed through and viewed multiple lava flows, which were all titled on the wall rather than being horizontal. There was also evidence of faults, which also happened to be weaker spots in the rock, often where miners climbing up could be killed. As we got further in, we got closer to where the copper was found. Like I mentioned in my last post, the native copper here was formed from hydrothermal fluids and rose through the cracks and holes of the now cooled lava flows and conglomerates. It then cooled and mineralized into copper and other minerals!
This trip was really neat! And there's still more trips to come.
