It is a term used for a highly weathered (terrestrialized) meteorite.
The use of “shale”, I suspect, came from the tendency of some
highly weathered meteorites, specifically highly oxidized iron
meteorites to develope a layered structure as they weather and
break into subparallel / parallel layers like shale when broken.

The terms “shale balls” and “iron shale” is also used for
some highly weathered meteorites.
