9 and sedimentary materials including: ultramafic and mafic rocks (essentially basalts), acid lavas and tuffs, chemical sedimentary rocks such as banded ironstone, jaspilite and chert, and clastic sedimentary rocks comprising shale, siltstone, sandstone, greywacke and conglomerate. Metamorphic belts are mineralized and tend to form ranges of hills, as they are harder and more resistant than gneiss and granite ‐ the latter generally underlie plains, particularly sandplains. The major soil type present in the Murchison region is shallow earthy loam overlying red‐brown hardpan. The Upper Murchison subregion of Beard’s (1976) Murchison region is described as generally hilly and undulating terrain, with shallow soils and granite exposure in the hills. The Weld Range and the Jack Hills are the main ranges of the subregion, and are formed by resistant metamorphic rocks (Beard, 1976). These greenstone belts exhibit banded ironstone formations (Elias, 1982). Curry et al. (1994) describe the Murchison River catchment and surrounds as an area dominated by granite‐ greenstone terrain, while very flat plains derived from colluvium and alluvium widely separate the hill ranges. Soils are predominantly shallow, sandy and infertile, and are underlain by red‐brown siliceous hardpan across most of the lower areas. The terrain of the Yalgoo subregion of Beard’s (1976) Murchison region is undulating and moderately dissected, with small remnants of the Tertiary land surface existing as sandplains. Low ranges of hills are created by metamorphic rocks. An inventory and condition survey of the Sandstone‐Yalgoo‐ Paynes Find Area was carried out by Payne et al. (1998). They describe the area as dominated by granite‐greenstone terrain, with gently sloping pediments widely separating occasional ranges. Sheetflood alluvial plains (very gently inclined) are upslope from salt lakes. Most soils are characterized as shallow, sandy and infertile, generally with the lower areas underlain by red‐brown siliceous hardpan.
Rogers (1996) conducted an inventory of soil and land resources of the Geraldton agricultural region, covering an area of approximately 20,600 km 2 . The Project Area incorporated the Shire of Mingenew and the agricultural zones in the Shires of Chapman Valley, Greenough, Irwin, Morawa, Mullewa and Northampton. Fifty‐one soil‐landscape systems are described, based on geology, landform and soil characteristics in this area. The Freehold section of the Project Area crosses 10 of the soil‐landscape systems mapped in the Geraldton agricultural region and a summary of these soil‐landscape systems is provided in Table 2.4. The most commonly occurring soil‐landscape systems in the Freehold section of the Project Area were the Dartmoor (27.4%), Eradu (20.1%) and Binnu Systems (14.3%). The soil‐landscape systems with the highest percent of the total system area contained in the Project Area were the Greenough (11.8%), Moresby (7.5%) and Dartmoor Systems (6.7%).

Land systems are described using the biophysical characteristics of geology, landforms, vegetation and soils (Curry et al., 1994; Payne et al., 1998). Curry et al. (1994) undertook a regional inventory of the Murchison River catchment and surrounds to document the land systems present and the condition of each. The Project Area covered 88,360 km 2 , extending between Meekatharra and Mount Magnet in the east, to the catchments of the Greenough and Wooramel Rivers in the west. Payne et al. (1998) carried out a regional inventory of the Sandstone‐Yalgoo‐Paynes Find area to document the land systems present and the condition of each. The Project Area covered approximately 94,700 km 2 . The Pastoral section of the Project Area crosses 30 of the land systems mapped by Curry et al. (1994) and Payne et al. (1998), these land systems are described in Table 2.5. The most commonly occurring land systems in the Pastoral section of the Project Area were the Yanganoo (19.8%), Tindalarra (16.3%) and Challenge (9.6%). The land systems with the highest percent of the total land system in the Project Area were Yarrameedie (10.3%), Weld (9.7%) and Millex (6.0%). The soil‐landscape and land systems have been mapped together and an overview map is provided as Figure 2.4. The soil‐landscapes are mapped as Figure 2.5 and the land systems are mapped as Figure 2.6 to Figure 2.8.
