RE: [asa] meteorites in the geologic column

The primary period of cometary and asteroid bombardment ended more than 3.8
billion years ago. There is also a Late Heavy Bombardment period:


Geological strata is much younger, of course, so a lack of meteorites is
expected. There was much happening during the first billion years or
so: nearby stars would send nascent Oort Cloud objects plunging in, most of
the planets were migrating inward, smaller particles were moving outward due
to Solar outflows, planetary resonances tossed objects to and fro, etc.
Once the planets settled into their orbits and the disk vanished, only
occasional meteor activity occurred. The few meteor showers we see today
come as a result of the Earth intersecting the orbit of a comet.


The problem is in the original premise, “if the meteor flux was essentially
constant”. Bah!

Subject: [asa] meteorites in the geologic column


This morning as I was scanning radio stations in the car, I came across John
MacArthur's "Grace to You" program.

Since Sept. 8 he has been doing a series on creation and today he was
talking about Day 3. No, I haven't gone back to listen to all those
segments. Reading the blurbs is enough of an indication of his message.


Today he brought up a YEC claim that I hadn't investigated myself and I
wondered if any of you had. His point was that if the meteor flux was
essentially constant over the geologic periods, then meteorites should be
found throughout the historical sedimentary rocks. Yet, he says, no
meteorites have ever been found other than at the surface. Hence, there was
no extended age of the universe prior to the flood when all the sedimentary
rock was deposited.


What is the actual distribution of meteorites with respect to location in
the strata?
