Geology of East Greenland

[@CASternbach]

This excellent presentation puts much more than just Greenland in a geologic context; it includes Scotland, Iceland, and other areas.

Thanks for your superb presentation, James. I visited East Greenland a few years ago. One of the best trips ever! I booked with a photography workshop, and had no idea of the varied geology I would see. My assumption was that I would be exclusively cruising in fjords carved through basement rock. Getting surprised by the geology actually made the trip extra special, but as a geologist, I am ashamed of my lack of pre-trip research.

Actually he is wrong about the "last ice age". We are still in that ice age. Ice ages are periods when one or more polar ice sheets exist on the planet. The current ice age began 45.5 Ma with the first formation of the East Antarctic Ice Sheet. It intensified quite considerably 2.5 Ma at the start of the Pleistocene. What he really means to say is that ice was more extensive during the last glacial. He is also wrong about the number of ice sheets during that glacial. There were actually five ice sheets, not three. There were the Greenland Ice Sheet, the Iceland Ice Sheet, the Laurentide Ice Sheet, the Cordilleran Ice Sheet and the Fennoscandian Ice Sheet.

How do you carbon date three billion year old rocks? Carbon-14 has a half life of 5700 year. Carbon-14 would be long gone in your three billion year old rock specimens.
