Time-equivalent magmatism in different provinces does not necessarily imply cogenetic magmatism. The informal event names are taken from dated examples. Dominantly mafic-ultramafic rock units are shown with bold colours. Subordinate mafic-ultramafic rocks of the same age within a regional rock package are shown with pale colours. Note that the presence of mafic and ultramafic rocks in some areas is interpreted only from geophysical data. Further occurrences of these rocks may exist under cover. The Early Cambrian Kalkarindji Event is included owing to the importance of this large magmatic event.

mafic rocks onlymafic and ultramafic rocks

Magmatic Events (ME) are defined from the published ages of mafic and ultramaficrocks in each province and shown in the 'Time–Space–Event' Chart (on accompanyingSheet 2). Time-equivalent magmatism in different provinces does not necessarily implycogenetic magmatism. The informal event names are taken from dated examples. Dominantly mafic-ultramafic rock units are shown with bold colours. Subordinate mafic-ultramafic rocks of the same age within a regional rock packageare shown with pale colours. Note that the presence of mafic and ultramafic rocks in some areas is interpreted onlyfrom geophysical data. Further occurrences of these rocks may exist under cover. The Early Cambrian Kalkarindji Event is included owing to the importance of this largemagmatic event.
