The "wheat belt" and "gold fields" of southern Western Australia are associated with a regional acid saline groundwater system. Groundwaters hosted in the Yilgarn Craton there have pH levels as low as 2.4 and salinities as high as 28%, which have greatly affected bedrock and subsurface sediments. This is manifested above ground as hundreds of shallow, ephemeral acid saline lakes.
