The mesmirizing melt inside a sliced and polished sample of the Sudbury Impactite. One of the world's largest craters was created by a 10 km-wide asteroid (or comet) smashing at uber-velocity into proto-North America 1.85 billion years ago. The impact structure has since been pinched north-south and elongated east-west to 190 km length by plate tectonics. Sudbury geology maps show the concentric rock formations outlining this now-elliptical ancient crater. en.wikipedia.org/wiki/Sudbury_Basin#Formation and en.wikipedia.org/wiki/Sudbury_Basin 9 x 6 inch slab of Grey Onaping Fallback Breccia is from road cut on Highway 144 near Dowling, Sudbury District, Ontario and acquired by yours truly at a high-quality geostore in Westport Ontario. The owner of Rox Rock Shop who collected, cut and polished this wow-grade material has a fair bit of neat local offerings among much global goodies. Further linkage to the power and extent of the Sudbury impactor as seen in impact debris 600 miles away in Thunder Bay. flic.kr/p/deHLxy
