Details (Known As) |
Second Valley Coastal Cliffs Geological Site |
Registered Name |
Geological Monument - Second Valley Coastal Cliffs |
Significance |
The coastal cliffs of Second Valley, both in the harbour area and to the north and south, contain excellent exposures which supply a wealth of geological information important to the interpretation of the complex tectonic evolution of the Adelaide Fold Belt. A major mountain building episode some 500 million yeas ago resulted in an extensive chain of mountains, part of which included the Mount Lofty and Flinders Ranges.
Numerous examples of complex mesoscopic folding and structural elements in Precambrian marbles and slates are clearly evident in the cliff faces which expose profile sections of the folding, enabling the true symmetry of the folds to be observed. Subsequent geological history is indicated by debris from Late Palaeozoic glaciation and Holocene (last 10,000 years) coastal features. (HB Assessment Report) |
