siehe auch V. Buchwald (1975) Handbook of Iron Meteorites, Vol. 3, pp. 880-882:

Nedagolla is a unique meteorite. So far, it is the only iron which shows unambiguous evidence of rapid solidification from
a melt, followed by rapid cooling to low temperature. It is difficult to reconstruct the original body, but it is almost certain
that it was not a normal hexahedrite or a coarsest octahedrite, because the trace element concentration is significantly
different.

Danke für den Hinweis, Bernd.

Knappes Fazit auch hier, ebenfalls publiziert in Sept. 2021:

Collisional mixing between inner and outer solar system planetesimals inferred from the Nedagolla iron meteorite

Jedenfalls sehr interessant!
