Location: | 574598. 11 kilometres south of Goongerah. | Tor fields (arrowed) on Mount Ellery. |
Abstract: | Spectacular tor development in Ellery granodiorite. | |
Access: | Ferntree track, B.A. Road via Sardine Creek Road off Bonang Highway. | |
Ownership: | Crown Land. | |
Geology: | Dislocation of the Ellery Granodiorite massive by faulted inliers of Ordovician sediments is a marked feature of the area. The Ordovician granodiorite contact is displayed in cuttings on t he track to Mount Ellery. The granodiorite is bounded on the west by the Kuark Fault and bisected by the Goolenggok Fault. Metamorphism of the Ordovician sediments is limited to the southern contact area where the Kuark Metamorphics are represented as hornfels, schist and schistise sandstones. The Ellery Granodiorite is exposed in large tors on Mount Ellery and is typically biotite rich, of moderate grain size and has been isotopically dated at 381 plus/minus 8 x 106 years or Lower Devonian in age. | |
Geomorphology: | Mount Ellery (1291 m), represents a residual which projected above a former widespread peneplain It displays spectacular tor development, the tors commonly standing between five and ten metres in height. | |
Significance: | Regional. although tor development is common on the granite slopes in the study area, the tor display on Mount Ellery provides the most spectacular example of such landforms. | |
Management: | Apart from large scale removal of tors, the geomorphological/ geological value of the site would not be seriously degraded by localised land disturbance, e.g. road construction, extractive industry or forestry. |
