Application of petrologic data collected on a regional scale in the Tanami-Northen Arunta Domain, Northern Territory, Australia defines a general increase in metamorphic grade/facies from northwest to southeast within an overall regional Low-Pressure/Low to High-Temperature metamorphic style domain. Within the overall lower grade metamorphism in the northwest Tanami, local increase in metamorphic grade relates to thermal effects of emplaced granitoid intrusions.
