Geology of A Salt Lake
November 3, 2024Those who have been on our Come Fly With Me photography workshops in the Victorian Mallee, might be interested in the geology of the area, which has resulted in the abstract patterns and formations around the edges of the lakes, that we look for and photograph.
The following map and cross section shows the relationship between Lake Tyrrell, Lake Wahpool and Lake Timboram and the associated catchment areas. The map comes from a review undertaken of the favourability of Australian salt lake systems from arid areas for potash, lithium, boron, and calcrete-hosted uranium deposits.
Lake Tyrrell is located in the Murray-Darling Basin. The salt is a result of this area of the continent being inundated by the ocean in successive cycles of changing sea levels. Around 2.5 million years ago the sea level appears to have been 65 metres higher than current levels. In the following map Ma refers to Miocene Age
