Sterling:
Sounds good to me (though I study big rocks that you can see with a
telescope). It sounds like it is time for me to start reading up on tektites
too!
As a novice, would you basically say that tektites come from volatilized
material that has recondensed while an impactite derives
Sterling:
Hello, as I told Tracy in a direct email, I was better in science than
history. In reading the accounts of the 1859 aurora, it's amazing that
knowing it happened has been ignored by communications and power companies.
It would be devastating if (when) it happens again. Tracy,
I'm sure the data I'm looking for doesnt exist in a handy format anywhere,
but I figured I'd ask the smart people of the meteorite list incase it does.
does any one know of a handy tabular collection of data on meteoriod entry
angle vs strewnfield ellipse dimensions for various types of stone
It would be difficult to compile such a list. Where a meteorite results from
an object that experiences a single fragmentation event (which presumably
describes most cases), the strewn field is not strongly related to the entry
details, but is instead defined by the wind conditions at the time.

Thanks for the detailed reply.
What about a listing of strenfield dimensions sorted by type of stone?
Thanks.

Hello everybody,
just wanted to let you know that I'am in the market for a moderately priced
piece of the Kendleton L4 meteorite. Specimen should be a slice, partslice
or prefferedly an endcut but should not exceed 5 mm in thickness.
Thanks for any offers in advance.

I know a formula does exist for this because I did my

It involved a lot of empirical evidence and

Hi Rob-
I think your methodology probably resulted in a biased formula. Falls
connected with witnessed fireballs are strongly associated with shallow
entry paths. Shallow paths produce multiple fragmentation events, or single
fragmentation events that extend over a long ground path. This

Hi All,
Have you ever wondered how many hours you must spend before your first
cold find ? Or how many hours after you find a new area with a new
meteorite before your next find?
I would like to say that you will find a meteorite every 40- 50 hours
of searching for cold finds not counting
Chris
I dare say you are right about it being a biased
formula and the data set we had to work with was very
limited as you point out. Thoroughly documented falls
leading to strewn fields of known dimensions may even
have been less than 5 at the time but memory isn't
that great after these
