Rock Number: 1
-a much better exposure of core granite
-outcrop surface spotted with small hematitic pits, some may be residual magnetite but others may represent pits left by MV knots derived from the sandstone weathering out
-matrix grain size 1mm with phenocryst grain size ranging to 12 mm suggestion of layering or banding shown by variations in grain size and phenocryst population
-rock appears to be typical of primative 2-mica peraluminous late granite
