Late Proterozoic peralkaline intrusives of the Alligator Rivers region, Northern Territory
The Mudginberri and Maningkorrirr Phonolites in the Alligator Rivers region consist of swarms of discordant peralkaline dykes that intrude Archaean to late Early Proterozoic rocks. Samples have given a Rb-Sr isotopic age of 1316 Ma. The dykes are phonolitic in composition and typically porphyritic, containing alkali feldspar, nepheline, sodic pyroxene, and minor biotite and apatite. In some small globules of mostly alkali feldspar may be products of liquid immiscibility. The dykes intrude part of the stable North Australian Craton and may represent late differentiates of concealed alkaline magma, as there are no other alkaline intrusive rocks known in the region. Alternatively, they may have formed by incipient melting in the upper mantle and deep crust.
