Abstract
Important mineral assemblages of metapelite and quartzite of the Strathgordon area are phengite + chlorite + tourmaline + quartz and phengite + garnet + chlorite + tourmaline + quartz. Over a limited area the Si4+‐content of phengite does not vary significantly and is considered to depend only on the PT regime. The Si4+‐content of phengite coexisting with almandine‐grossular‐spessartine garnet and tourmaline indicate that the maximum metamorphism of the area occurred at 400 ± 50°C and 3 ± 1 kb.Keywords
