Abstract

Results of röntgenographic examination of 30 untreated mineral soil samples from various parts of Finland were compared with their total contents of Ca, Mg and K. Within the different textural classes, an abundant occurrence of biotite and illite usually corresponded to a relatively high content of Mg.
