Geology Lesson #5, with Capt. Paul and Dr. Nat (also known as Paul and Nathalie Brandes). Our Pasty Cam instructors take us to Deer Lake, north of Ishpeming for today’s lesson. Capt. Paul explains a bit about the Kitchi Formation in the notes here below:

“Today we are featuring the Kitchi Formation, a metamorphosed succession of basalt flows, volcanic breccias, and volcanic tuffs (ash deposits). The photos attached are of the volcanic metabreccia unit that outcrop near Deer Lake north of Ishpeming. The rocks here are of the middle Kitchi Formation and are approximately 2.7 billion years old, approximately the same age as the pillow basalts we looked at earlier. Though metamorphosed, the original andesite/dacite clasts are still very well defined. One photo (3866) shows a remarkable feature, a micro-fault that cut across one of the clasts sometime after the deposit was laid down and metamorphosed. This unit of the Kitchi has been interpreted to represent a... well, you’ll just have to watch the video to find out!”

Another very nice presentation from; The Rockadile Hunter.

This is amazing - to understand how these rocks were formed. Just nothing even remotely related to anything i've learned before. How far can these formations be found?

Is there any relation of the name Kitchi with Kitch-Iti-Kipi? Very similar.

Thanks again - keep these coming!
