Multi-element soil survey of the Mount Hope Area, Western Australia
Lintern, M.J., Churchward, H.M. and Butt, C.R.M.
Composite soil auger samples from the top metre were analysed for
elements and compared with similar existing information for Au.
Regolith and geomorphological features were mapped from air photo
and field studies and, in conjunction with existing geology maps,
were used to interpret the observed distribution of the elements.
Initially, simple distribution maps, selected binary plots, histograms
and correlation matrices were used to describe the results. Further
statistical treatment using R-Q mode principal component analysis
and cluster analysis developed the interpretation. The results demonstrated
strong associations between certain elements, soil type and underlying
geology. Most notable were the associations between SiO2 and sediments,
transition metals and the laterites, and alkali and alkaline earth
metals with the red earth soils. Whilst Au itself did not show any
strong associations, certain areas have been identified from this
integrated approach that warrant further investigation.
