Figure 7

Electron micrographs showing the occurrences of ilmenite in gaerome and kibushi clay. BSE images (a,b) (a polished section) show leached ilmenite in an ilmenite grain of the gaerome clay (A07), indicating leached ilmenite as an alteration product of ilmenite. SEI (c,d) show a strongly corroded ilmenite grain in the kibushi clay (A08). BSE images (e,f) show framboid-like aggregates of ilmenite-pseudorutile in the kibushi clay (A08).
