Figure F7. From Figure F2 of Hillenbrand and Ehrmann (Chap. 8, this volume) showing the percentages of smectite, illite, and chlorite in samples from Site 1095, plotted against depth. Typical modern glacial and interglacial compositions persist throughout the 9-m.y. section (see text). Compare this evidence of ice sheet volume with the climatic evidence of Figure F8.
