dc.description.abstract |
We review the nature and importance of soil factors implicated in the formation
of secondary ferrimagnetic minerals in soils and palaeosols worldwide. The
findings are examined with respect to temperate regions through a comprehensive
analysis of over 5000 samples of surface soil from England and Wales taken from
a 5 × 5 km grid. Over 30 soil and environmental attributes are considered for
each sample as proxies for soil forming factors. Measurements of low field
magnetic susceptibility (mass specific) and frequency dependent susceptibility
(mass specific and percentage) on each sample provide estimates of the
concentration and grain size of ferrimagnetic minerals. Maps of soil magnetism
across England and Wales show non-random distributions and clusters. One subset
of data is clearly linked to contamination from atmospheric pollution, and
excluded from subsequent analyses. The concentration of ferrimagnetic minerals
in the non-polluted set is broadly proportional to the concentration of minerals
falling into the viscous superparamagnetic domain size range (~ 15–25 nm). This
set shows clusters of high magnetic concentrations particularly over specific
parent materials such as schists and slates, mudstones and limeston |
