Clay Mineral Society 1989



Two themes emerged from the Clay Mineral Society's 1989 meeting: We need to consider larger samples, whether in theoretical or experimental work—count more spacings in HRTEM photos, and take multiple samples from single locations; and the configurations R0, Rl, (R2) and R3 have some kind of distinct stability. Kaolinite also got its share of attention, even though no session was devoted to it.

The society met September 23–28, 1989, at California State University, Sacramento; 195 scientists attended. Although there were fewer presentations than in recent years, participants agreed that quality was improved and that more time allowed for more and better discussions.
