Figure 6

Electron micrographs (a,b) are secondary electron images (SEI) of gaerome and kibushi clay, respectively. Electron micrographs (c,d) are back scattered electron (BSE) images of polished sections of gaerome and kibushi clay, respectively. The aggregate grains comprise mainly fine-grained kaolinite (gray parts) and fragments of K-feldspar and quartz. Electron micrographs e and f are SEI of K-feldspar in gaerome clay. The decomposed surface of K-feldspar resembles an etched texture.
