Re: Meteorite Imapact Depth Study
Bill,
I don't know of any compilation of crater depth, but you might find the
information for specific structures or meteorites.
Craters are usually classified as "dug," those formed by small meteorites
impacting in relatively soft material, usually a few to several centimeters or
even meters deep; "simple" craters that are relatively small and have
depth-to-diameter ratios in the 1:5 to 1:7 range; and "complex" craters with
central uplifts and/or uplift rings that have depth-to-diameter ratios of
about 1:10 to 1:20. On Earth the transition from simple to complex usually
takes place with craters in the 2 to 4 kilometer range.
Then there are all those pesky meteorites that are found lying about on the
ground or just slightly depressed. I don't know if anyone has thought to
develop a ratio of the number of surface finds to "dug" finds, but the
condition variables you list in your post will certainly have an affect on the
final resting place of meteorites, as it were.
