Jadeite, Nephrite & Serpentine

The presence of magnetite makes the serpentinite rock partly magnetic (Fig. 5). So if a green "Jade" contains dark gray to black inclusions, then do the magnet test. If the stone and magnet attract each other, then the black inclusions are magnetite and consequently the green rock as a whole is a serpentinite.

Structural setting, wall rock alteration and gold

Field mapping, drill-core logging, petrography, laser ICP-MS analysis on pyrite, chlorite geothermometry and geochemical analysis of hydrothermally altered rocks reveal two distinct styles of gold mineralisation at Mt. Percy. The first style is D2 shear zone-hosted and correlates with Fimiston-style mineralisation documented in the Golden Mile. Laser ICP-MS …
