Heterogeneous gray TTG gneiss. Two generations of granite veins occur which are shortened in NS direction, while one generation of dykes is undeformed. Probably, the folded dykes are Wooramel material, (1965-1945 Ma), and the undeformed veins Moorarie (1830-1780 Ma), which suggests that main deformation to belong to the Capricorn orogeny. Yarweelor Gneiss (reworked Yilgarn gneiss – protolith 3.7-2.4 Ga). Looking NE
