Abstract

The Gilmore Fault Zone is a long-lived imbricate fault system separating the Wagga Metamorphic Belt from the Tumut Block in the Palaeozoic Lachlan Fold Belt. Structures within the fault zone indicate dominantly sinistral transpressional movements during regional deformation in the Siluro-Devonian and mid-Devonian and/or Carboniferous. These movements, in response to lateral compression, resulted in the Wagga Metamorphic Belt being thrust over the Tumut Block. Dextral strike-slip movement may be inferred during Early Silurian regional deformation and subsequent extension. Common structural and metamorphic histories, and lithological correlation of rock units straddling the fault zone, indicate that the Gilmore Fault Zone was not a terrane boundary in the Late Ordovician or Early Silurian. Differences in geophysical expression and crustal composition across the southern part of the zone would be explained if the zone is a reactivated basement fault which corresponds, in part, to an older terrane boundary. The fault zone is interpreted as a splay off a gently west-dipping mid-crustal detachment.
