WebMoved Permanently. The document has moved here. WebWestern Australia has numerous recorded graphite prospects and occurrences. Almost all are found in graphitic schists or gneisses derived from the metamorphism of carbonaceous sedimentary rocks ranging from Archean to Mesoproterozoic age.

Furthermore, the AB soil spiked with graphite, as an additional sample without natural graphite but with a high CaCO 3 content (1.87 % C), showed a similar underestimation as observed with the calibration samples (Fig. 5).
