| Inhoud: |
The Barry Granodiorite is a weakly deformed I-type, and the Sunset Hills Granite is a moderately deformed S-type, granite. Both granites were passively intruded into an already foliated greywacke and volcanic sequence. Emplacement may have been facilitated by faults related to the oblique opening of the late Early Silurian Hill End Trough. The granites display a dominant foliation which formed during the late Middle Devonian and subsequently was reoriented during the Early Carboniferous. The Barry Granodiorite and Sunset Hills Granite are on the margin of north-south ductile shear zones related to the Wyangala Batholith. These granites and the adjacent Carcoar Granodiorite have undergone reorientation during movement on ductile shear zones either due to megakinking during late-stage north-south shortening, or southeastward movement of the southern margin of the west-northwest-trending Lachlan Transverse Zone. |
