[meteorite-list] Odessa Crater (Texas) Determined to be About 63, 500 Years Old

[Paul]

In December 2005 issue of “Geology” the below article about
the Odessa Crater in Texas has been published.

Holliday, Vance T., Kring, David A., Mayer, James H., and 
Goble, Ronald J., 2005, Age and effects of the Odessa 
meteorite impact, western Texas, USA., Geology. vol. 33, 
no. 12, pp. 945–948. 

This article noted that optically stimulated luminescence 
dates of sediments filling it demonstrate that this crater was 
created about 63,500, plus or minus 4,500, thousand years 
ago.

The same issue of Geology also has the following articles:

the Chesapeake Bay impact? Insight from numerical modeling. 
Geology. vol. 33, no. 12, pp. 925–928. 

They concluded that the original transient crater was only 40
 km in diameter. The full abstract can be found at:
