Summary
[edit]DescriptionOdessa Breccia (Upper Pleistocene, 64 ka; Odessa Impact Crater, Texas, USA) 4.jpg |
English: Impact breccia from the Pleistocene of Texas, USA. (cut surface; ~10.5 centimeters across at its widest)
Impact breccias are poorly-sorted, clastic-textured rocks having angular large clasts. They form when asteroids or meteoroids impact the surface and pulverize rocks in the target area. Seen here is an impact breccia from Texas, the Odessa Breccia. This deposit formed when an iron meteorite hit the western Texas plains during the Late Pleistocene, about 64,000 years ago. The impact site is 9-10 miles southwest of the town of Odessa, Texas. The main crater is somewhat subtle as seen from the ground. Fragments of Odessa Meteorite have been collected from the surrounding fields for decades. Locality: Odessa Impact Structure, Ector County, western Texas, USA. |
