Fig. 7.

Representative scanning electron microscope images of polished sections for (a–c) accepted and (d–f) rejected samples in paleointensity determination. (a, c, and d) Backscattered electron (BSE) images for frequently observed iron oxides in samples from the lava flows showing (a) anhedral to subhedral iron oxides, (c) ilmenite lamellae, and (d) a thick rim of iron oxide reflecting secondary alteration. (b, e, and f) BSE images of iron oxides in samples from the massive basalts showing (e) dendritic and cruciform iron oxides, and (f) a trellis texture.
