Note that Lungau is used in Mindat as a sub-level for Salzburg localities, because the area is perfectly defined by geographic boundaries: high mountain ranges to the north and west and the Carinthian and Styrian borders - again represented by high mountain ranges - to the south and east, respectively.
The remaining Salzburg localities are NOT assigned to the Pinzgau, Pongau, Tennengau and Flachgau regions (the remaining 4 of the 5 regional names for larger areas in Salzburg) because this would have severe implications for the Pinzgau/Pongau and Pongau/Flachgau boundaries in that important geologic formations and historical mining districts (Mitterberg, Werfen, Tennen Mts) would have to be split up.
