Summary:The Harts range region consists of several essentially independent terrains: 1) the Strangways orogenic belt (SOB), S of the Muller thrust; 2) the SOB of the Oonogalabi tongue; 3) the SOB of the Entia Dome (together comprising a basement); and 4) the Harts Range 'cover' (HRC). Thrusts or faults separate them all. The terrains consist of supracrustal sequences of metasediments and some metabasites, thought to have been deposited in extensional rift depressions, plus varying amounts of intrusive granitoids. Evidence suggests equilibration of the SOB S of the Muller thrust at 700-800 degrees C and 5-7 kbar, and of the HRC in the Ruby Mine area at 680-780 degrees C and 6-8 kbar. Some thickening due to compression is considered necessary. [R.E.S.]
