So far there are only six irons that belong to this group: Auburn, Bellsbank, Guanaco, La Primitiva, Tombigbee River, and Twannberg. According to J.T. Wasson, Guanaco and La Primitiva are closely related but sufficiently different and should therefore be considered two different Chilean irons.
My 26.5 gr part slice of Guanaco features a massive schreibersite inclusion and countless, narrow-spaced Neumann lines. |
