Patterns of glacial dispersal of heavy metals as reflected by

The tonal discontinuities evident on unenhanced Landsat MSS images
of vegetation overlying the known area of a heavy-metal glacial
dispersal train are investigated. Samples of soils developed on
the glacial deposits and of plants growing within and outside the
dispersal train were analyzed for Ni, Cr, Co, Mg, Cu, Mn, Fe and
Ca. Trace element concentrations in the plants are observed to
follow those of the soil, with environmental factors determining
the types of plant communities present in various regions. Data
also indicate that high levels of nickel may act to reduce a
plants ability to produce chlorophyll, as evidenced by the
presence of scrub communities on soils highest in nickel.
