. Fig. 29.25 Pole figures from the austenite (top) and the ferrite (bot-
tom). In the austenite pole figures the single orientation of the austen-
ite is shown by the arrangements of the poles that are shown. This was
also observed from. Fig. 29.23b. The complexity of the ferrite pole
figures is due to the many crystallographic variants of ferrite that form
from the single orientation of austenite

in the Gibeon meteorite. The sample was prepared with conventional FIB
followed by low voltage ion FIB milling at 5 kV. a Secondary electron SEM
