L178 Central Victoria (Stawell / Bendigo / Melbourne Zones) Seismic Transect, VIC, 2006 Stacked and Migrated Seismic data and images for line 06GA-V1, 06GA-V2, 06GA-V3, and 06GA-V4
A ~400 km long deep crustal reflection seismic survey was acquired in central Victoria, Australia, in
2006. It has provided information on crustal architecture across the western Lachlan Orogen and has
greatly added to the understanding of the tectonic evolution. The east-dipping Moyston Fault is
confirmed as the suture between the Delamerian and western Lachlan Orogens, and is shown to
extend down to the Moho. The Avoca Fault, the boundary between the Stawell and Bendigo Zones, is
a west-dipping listric reverse fault that intersects the Moyston Fault at a depth of about 22 km, forming a
V-shaped geometry. Both the Stawell and Bendigo Zones can be divided broadly into a lower crustal
region of interlayered and imbricated metavolcanic and metasedimentary rocks and an upper crustal
region of tightly folded metasedimentary rocks. The Stawell Zone was probably part of a Cambrian
accretionary system along the eastern Gondwanaland margin, and mafic rocks may have been partly
consumed by Cambrian subduction. Much of the Early Cambrian oceanic crust beneath the Bendigo
Zone was not subducted, and is preserved as a crustal-scale imbricate thrust stack. The seismic data
have shown that a thin-skinned structural model appears to be valid for much of the Melbourne Zone,
whereas the Stawell and Bendigo Zones have a thick-skinned structural style. Internal faults in the
Stawell and Bendigo Zones are mostly west-dipping listric faults, which extend from the surface to near
the base of the crust. The Heathcote Fault Zone, the boundary between the Bendigo and Melbourne
Zones, extends to at least 20 km, and possibly to the Moho. A striking feature in the seismic data is the
markedly different seismic character of the mid to lower crust of the Melbourne Zone. The deep seismic
reflection data for the Melbourne Zone have revealed a multilayered crustal structure that supports the
Selwyn Block model.
