Abstract
A dryland salinity scald some 48 km2 is described from Yelarbon on the border of Queensland and New South Wales, near the headwaters of the Murray-Darling River Basin. The saline soils, including solodised solonetz, are severely eroded and readily identified on Landsat MSS imagery. A major fault (Peel Fault offset?) beneath the scald has caused saline groundwater to leak up into the soil zone preferentially at this location. The evidence for this includes regional tectonic setting, detailed site geology, a magnetic geophysical anomaly, surface drainage changes and land surface displacement, hydraulic gradient changes, and groundwater hydrochemical anomalies. Erosion of the geologically caused saline scald is being aggravated by overgrazing. An appropriate land management strategy is to fence the area and assign it nature reserve or national park status.
