Abstract

The data from the Hero/Western Fault Zone and the Paroo Range indicate almost continuous east-west compression and north-south tension, concurrrent with north-south strike slip changing from transtensive to transpressive over distances of a few tens of kilometres. Whether the fundamental regime was strike-slip with subordinate tension and compression, or alternating compression and tension with strike-slip transfer faulting as a derivative, remains at present unanswered. Data from this western part of the Mount Isa Inlier seem to corroborate those of Loosveld (1989) from the easternmost part near Cloncurry, suggesting that these areas were the shoulder of a basin for which the Kalkadoon Basement formed the centre. -from Authors
