Electron Micrography of Till Matrix
John B. Droste, George W. White, Albert E. Vatter
Wisconsin tills from northeastern Ohio were studied under the electron microscope as fragments from less than 1 to several microns and on surfaces as large as inch, using carbon replica techniques. Subhedral "grains" are composed of illite and chlorite; anhedral "grains" are kaolinite. Kaolinite is absent from "late" Cary (just pre-Defiance) till. Nonclay minerals, quartz, feldspar, and calcite, are either absent or exceedingly rare in less than 2 micron sizes, but increase in amount in larger sizes and are common in larger than 4 micron grain sizes. The platy clay minerals are oriented more or less parallel to the horizontal plane of the till in place.
