IIRC, the impact of a meteor would result in vaporization of said
meteor due to kinetic energy. I'm not sure I understand the results of
vaporization. Are we saying matter destroyed or matter converted to
fine dust? In other words, would the vaporization result in a fine dust
cloud of particles that would settle and eventually form concretion of
meteor dust over a period of time?
Reason I'm asking, I live near a known impact site and 20-30 miles from
the site I often find a dark layer of concretion-like material 1"- 3"
thick that does not match the native soil. This layer of material
ranges from being on the surface to 3'-4' below surface, depending on
erosion. I have always wondered if this was related to the impact or
some other occurance. Just curious.

To say anything definitive about the dark layer, we would have to know its
constituents and age. Does the strata age match the impact age? If so, then it
could be an ejecta ray. However, that's unlikely. More likely is its due to
something else - streams, oceans, plants, volcanos, etc.
