The structural development and controls on mineralisation of the northern sector of the Norseman – Wiluna Belt, Western Australia
Supacrustal rocks in the Kathleen Valley – Lawlers District comprise mafic and ultramafic volcanic rocks with intercalated felsic volcanogenic rocks and black slates that are overlain by conglomerate – a typical succession in an Archaean greenstone belt.
There is an older association of theoleiitic sills and lavas with some komatiites; and a younger syngenetic komatiite-associated nickel sulphide mineralisation occurs. Three structural domains are recognized.
