The deposits comprise unconsolidated gypsum crystals in beds up to 2m thick within sediments of probable Tertiary age. The gypsum is |
|
exposed over a wide area in small gullies and on the edges of incised plateaux. The gypsum is suitable for agricultural |
|
use. The origin of the gypsum is unclear, but it was probably the remnants of a shallow salt lake formed in the Tertiary on the Cretaceous |
|
Winton Formation. |
