Barry Granodiorite and Sunset Hills Granite: Wyangala-style intrusion at the margin of a regional ductile shear zone, northern Lachlan Fold Belt, NewSouth Wales

The Barry Granodiorite is a weakly deformed I-type, and the Sunset Hills Gr anite is a moderately deformed S-type, granite. Both granites were passivel y intruded into an already foliated greywacke and volcanic sequence. Emplac ement may have been facilitated by faults related to the oblique opening of the late Early Silurian Hill End Trough. The granites display a dominant f oliation which formed during the late Middle Devonian and subsequently was reoriented during the Early Carboniferous. The Barry Granodiorite and Sunse t Hills Granite are on the margin of north-south ductile shear zones relate d to the Wyangala Batholith. These granites and the adjacent Carcoar Granod iorite have undergone reorientation during movement on ductile shear zones either due to megakinking during late-stage north-south shortening, or sout heastward movement of the southern margin of the west-northwest-trending La chlan Transverse Zone.
