... Groundwater discharge complexes, locally known as boinkas, are a distinctive feature of the Mallee region, the western sector of the Murray Basin (300,000 km 2 ) in southeast Australia. The discharge complexes are nested, with modern playas (salinas) set in late Pleistocene playa sediments...

... at high temperatures. The preservation of high-temperature mineral oxygen isotope fractionations and the lack of gross retrogression of the Mallee Bore rocks, indicates that fluid flow after regional metamorphism was negligible. Furthermore, the difficulties associated with downward circulation of surface...

... of the emplacement. The intrusion of the Mallee Gap Granite has only a local control on the hydrothermal alteration, but high potassic granites of the southern Mount Angelay Granite might have expelled oxidized mineralizing fluids and possibly had a major impact on regional scale alteration. Hyperspectral remote...

The dunes are covered by an open woodland of mallee (multi-stemmed eucalypt trees, principally Eucalyptus incrassata subsp. incrassata and E. socialis ) to 5 m height. Shrubs up to 3 m in height are predominantly Melaleuca uncinata (broombush). Smaller shrubs...

... direction (RDD) determined by Kalma et al. (1988) (Fig.  4 ) shows that there are regions in which there is close agreement and areas of divergence and even opposed wind and dune directions. There is reasonably close agreement (within 15°) between RDD and dune orientation in large parts of the Mallee...
