An analysis of joint patterns in the Grampians Group rocks o£ Western Victoria has established that the dominant directions are north-north-west, east-north-east, west-north-west, north-north-east and north. The master joints are steeply-dipping structures which formed after the sediments were lithified and folded. The joint-formation is not genetically related to the folding and post-dates the emplacement of the igneous intrusions. Joint orientation is independent of lithology and the sediments have reacted as a uniform mass to an applied stress. The joint pattern conforms with the regional tectonic pattern of faults and lineaments which includes directions of the regmatic shear pattern of Sonder (1947). The jointing and major faulting took place during the Kanimblan Orogeny. The faulting and joint-formation may have been contemporaneous, the faults being directions along which displacement occurred; conversely the actual movements along faults may have induced the jointing into the sediments. |
