ABSTRACT
Notes being incorporated into a report on laterite geochemistry
for the Moora, Perth, Pinjarra, Collie and Pemberton 1:250000 sheets
Innes, J., Smith, R.E. and Perdrix, J.L.
These notes support the presentation of regional laterite geochemical
coverage in part of the SW of the Yilgarn Block of Western Australia
to sponsors of Project P240, on 11 April, 1988.
The geochemical results of some 2000 samples of lateritic duricrust
materials are discussed. These represent: (a) all of the sampling
within the five 1:250 000 sheets, Moora, Perth, Pinjarra, Collie
and Pemberton, arising from research into laterite geochemistry
sponsored by Greenbushes Ltd. from 1980 to 1983, Fig. 1; (b) with
the addition of some sampling within these sheets arising from a
second phase of research sponsored by Greenbushes in conjunction
with St. Joe Minerals during 1983 and 1984, Fig. 2.
Accompanying these notes is a plot of the distribution of As in
laterite at 1:1 M scale, and a floppy disk of the data.
