1.24 kg. Impact Layer
Luther writes:
This 1.24kg specimen was collected by myself when I and other members of the British and Irish Meteorite Society re-discovered this amazing material in 2016. This material is an impact layer deposit, containing matter ejected by the impact that created the Manicouagan Crater in Canada 214 million years ago. It is the only known deposit linked to that event found outside of Canada.
Within the material, we find shocked quartz, shocked biotites and shattered garnet. The most outstanding feature of this layer is the presence of tiny (0.5-1.5mm) greenish clay spherules, which started out as molten glass droplets. Contained in a matrix of mixed material showing how the deposit was quickly laid down.

Luther, thanks for the sneak peak of the team's awesome findings. The droplets in the rock are bizarre. The new article about this effort that is in the May 2017 Space Rocks magazine is excellent. I want to find my own crater/impact area here in Pennsylvania. Always dreaming... |
