Zirconium Content of Coarse Silt in Loess and Till Of Wisconsin Age in Northern Illinois
1962
Alexander, J. D. | Beavers, A. H. | Johnson, P. R.
The zirconium content of the course silt fraction of 11 calcareous Wisconsin age till samples and 13 calcareous Wisconsin age loess samples was determined by the X-ray emission spectrograph. It was found that the mean zirconium content of the loess (0.055%) was approximately twice as high as in the glacial tills (0.022%). This difference in zirconium content may be used to help distinguish loess from till where separation is difficult by field methods and also should be helpful in soil development studies.
