Several Late Palaeozoic granites which intrude strata of the Silurian-Devonian Hodgkinson Province, north Queensland, display pronounced west-northwest-east-southeast orientations, as do a suite of brittle structures that have affected both the plutons and country rocks. These features define a 20 km-wide, west-northwest-trending zone, here named the Desailly Structure, which traverses the Hodgkinson Province and extends west across the Palmerville Fault into the Proterozoic Yambo Inlier. Deformation within the Desailly Structure was heterogeneously partitioned into zones of west-northwest-east-southeast faulting separated by tracts of competent country rock. The latter contain a pervasive north-south-trending structural grain which locally controlled pluton emplacement and resulted in a meridional orientation of many granitoid bodies. Initiation of the Desailly Structure is attributed to have occurred syn- to post-D-2 of the regional deformation history. It was reactivated in the Hunter-Bowen Orogeny (D-4), with the zone expressing an overall sinistral sense of displace ment.
