[meteorite-list] Canyon Diablo impact velocity

[bernd.pauli at paulinet.de]

=> At what velocity do you think Canyon Diablo impacted?

RODDY D.J. and SHOEMAKER E.M. (1995) Meteor Crater: Summary
of impact conditions (Meteoritics 30-5, 1995, A567, excerpts):

.. the meteorite had a velocity in the range of about 13 to 20 km/s, probably in
the lower part of this range ..., the coherent meteorite diameter is estimated
to have been 45-50 m with a mass of 300,000 - 400,000 t, i.e., large enough to
experience less than 1% in both mass ablation and velocity deceleration. During
this time, minor flake-off of the meteorite's exterior produced a limited number
of smaller fragments that followed the main mass to the impact site, but at greatly
reduced velocities.
