Geological base maps used:

� Distribution of Precambrian mafic and ultramafic rocks:

1: 500,000 Interpreted Bedrock Geology Map of Western Australia

by the Geological Survey of Western Australia (June 2001).

Many occurrences of mafic and ultramafic rocks under cover are

not shown.

� Distribution of dolerite dykes and sills:

Myers, J.S., Hocking, R.M., 1998.

Geological Map of Western Australia, 1: 2,500,000 (13th edition).

Geological Survey of Western Australia.

The ages of the dolerites are dominantly Proterozoic and Archaean.
