Mount Narryer

Kinny, P. D., Williams, I. S., Froude, D. O., Ireland, T. R. Compston, W. 1988. Early Archaean zircon ages from orthogneisses and anorthosites at Mount Narryer, Western Australia. Precambrian Research, 38, 325-341. 

The oldest known terrestrial materials are 4.1-4.4Ga detrital zircons from the Mount Narryer area of western Australia (Froude et al., 1983). The first locality to be shown to host extremely ancient zircons (4.1-4.2Ga) was a sequence of highly metamorphosed quartzites, conglomerates, and pelites from Mount Narryer, at the northwestern edge of the Yilgarn Craton in western Australia. Subsequent discoveries, in a less metamorphosed sequence of sediments from the Jack Hills, some 60 km away identified even older zircons, some 4.28 Ga old (Compston Pidgeon, 1986). Recently, Wilde et al. (2001) reported a zircon grain with an age of 4.404 0.008 Ga (Fig. 1.10). To date this is the...
