Bonjour Pierre-Marie, Hello List,

"a short question: is it possible that the Nickel Test is positive to
terrestrial irons (or usual old iron forge residues) and which ones?"

Well, terrestrial rocks like the P u t o r a n a rock will test
positive for nickel because of these nickeliferous components:

- Fe-Ni metal (2.3% Ni, 0.54% Co; 0.2% Cu)
- Cu metal (6.5% Fe, 1.2% Ni)
- Cohenite (91.1% Fe, 0.6% Ni, 0.04% Cu).

Another case is, as we all know, the Ovifak "pseudometeorite" with
its relatively high nickel content.
