| Abstract: | The Lachlan Fold Belt is a Middle Palaeozoic orogenic belt in which terminal tectogenesis occurred during the Early Carboniferous (Kanimblan Orogeny). This fold belt went through a complicated tectonic history and developed from the stratotectonic Lachlan Marginal Mobile Zone (or geosyncline of other authors). The Lachlan Fold Belt can be divided into structural zones which are characterized by varying tectonic styles. Zones of intensive deformation alternate with less deformed zones.The formation of the Lachlan Fold Belt may be viewed in terms of a series of tensional and compressional deformational events with the major compressional or tensional stress maintaining an approximate east—west orientation (relative to the grain of the fold belt) for the life of the Lachlan Marginal Mobile Zone. |
