Summary
| Description |
English: Impact breccia (suevite) from the Cretaceous of Russia. (wet, cut surface; ~9.9 centimeters across at its widest)
The eroded and buried Kara Impact Structure is located in the Polar Urals of far-northern Russia. The structure is about 65 kilometers in diameter, but may have been well over 100 kilometers in size. It dates to 70.3 million years ago, during the early Maastrichtian of the Late Cretaceous. Seen here is an impact breccia from the Kara Crater area. Several specific varieties of impact breccia exist (e.g., impact resurge breccia, melt-matrix breccia, suevite). This specimen is a suevite, a polymict impact breccia that includes glassy-textured and/or frothy-textured clasts derived from impact melting. Info. at: en.wikipedia.org/wiki/Kara_crater |
