GEOCHEMISTRY OF ANCIENT LANDSCAPES

The author of this article performed a combined mineralogical and radiological study of approximately 500 samples of clays and clayey fractions from 58 wells in the Carpathian foothills. As a result of this study, the author concludes that a combined mineralogical, geochemical, and radiological study of a complex of clayey authigenic and epigenetic minerals, as well as a study of the ions, organic matter, and water soluble salts absorbed by them, may provide an idea of the environmental conditions under which the rocks under study were formed.- -Scripta Technica, Inc.
