Fact sheet
Description: 

This quartzite has very low water content. The minerals in it are quartz, garnet and feldspar, but no mica.  The feldspar forms thin bands and tiny parallel lenses many of which are composed of mesoperthite/ The lenses are trapped in huge quartz grains. The quartz grain growth occurred after the feldspar was smeared out at a temperature >700°C, above the feldspar solvus.
