Abstract
Analysis of 475 Keewatin till samples from the Alberta Plains shows well-defined trends in the distribution of certain minor constituents and trace elements. Fe and Cu are most abundant in tills from the Clear Hills region of northwestern Alberta, in which area thin but widespread beds of iron-formation outcrop. Zn distribution in till also is related to bedrock composition and, together with Fe and Cu, is useful in delineating bedrock subcrop patterns. The distribution of CaO, although related to the carbonate content of the underlying bedrock on a regional scale, has been modified to some extent by glacial processes, as demonstrated in the Caribou Mountains area of northernmost Alberta.
