Tom,

Most of that "black stuff" is magnetite, a common
terrestrial mineral.

However, there might be a small fraction of it being
meteoric, but sorting it out would be a chore indeed.
Every grain would have to be tested for Ni, and even
then the question of meteoric origin would still
remain until further testing was done.

Only a government with funding to do such studies
would make the task perhaps worth someone's effort.
