The Delny-Mount Sainthill Fault System, a distinctive feature on satellite photographs, can be traced as a well-developed geological and geophysical feature extending some 130 km across the Arunta Block, central Australia. It has a slightly north-of-west trend, from 4 km south of Mount Thring (22°49S, 136°02E) to 5 km south of Delny Outstation (22°33S, 134°49S) (Figs 1, 2). The deformed nature of the rocks at Mount Saint4iIl was first noted by Smith and others (1960), who described a blastomylonite derived from nearby granite, and recorded the gradational contact between deformed and undeformed units. Shaw and Warren (1975) mapped the Delny section of the Fault System. The nature of the remainder of the Fault System and its continuity was recognised during rapid reconnaissance to provide data for interpretation of new coloured aerial photography in the 1976 field season.
