METEORITES
Odessa Meteor Craters
 |
"Long
before the Indians fought the white man on these plains, and even before
the Spaniards coughed dust of the New World prairie, a fiery body from
the heavens, leaving a tail of flame in its wake, struck near the
present town of Odessa, at a speed of 40 times that of any bullet fired
from a modern rifle."
from the
Odessa News Times, 1939 |
|
A local rancher found the first meteorite in the 1890’s, 10 miles
southwest of Odessa, but it was not until 1929 that J. M. Barringer, Jr.
firmly stated that he believed the depression to be a meteorite crater.

Glen
Evans was the geologist in charge of the exploration of the crater from
1939 until 1941, when the Bureau of Economic Geology took on the project
as part of a joint venture involving Federal, State and County agencies. |
|
The
craters result from a meteorite shower which fell about 17,000 years ago
in west Texas. Numerous specimens have been collected, some are badly
weathered, but all appear to be nickel-iron meteorites. |

Investigations
included study of the geological changes caused by the impact. Each
different pattern on the diagram below represents a rock unit. The
meteorites were found in the zone of solid black shapes at the base of
the crater. |

Sinking the shaft
in the main crater
It
was thought that the original impact body might remain at the
base of the crater. Numerous drill cores were taken over the
main crater as well as this major shaft building operation.
Unfortunately
no meteorite was found by the time the excavation had reached
solid rock layers of Triassic age.

No
major publication, other than a progress report, was produced by
the Museum at the time of the excavation.
However,
the recent publication by Glen Evans and Charles (Gene) Mear has
filled in that gap. |
