Inshore rock platforms (1) and gently inclined shore face. Erosion and deposition by marine tides, currents, and wave action. Small areas of man-made reclamation in urban areas at the coast (2). Dominantly shell and quartz sand formed by biogenic processes, reworking of fluvially sourced material from weathered hinterland rocks, or by erosion of reefs. Reefs or rock flats composed predominantly of eolian calcarenite. Currently active system that includes undivided older reefs probably of the Spearwood System. Primarily used for shipping, fishing industry, and recreation. Possible source of sand or limestone for construction, beach rebuilding, and reclamation. Shallow reefs are a hazard to shipping. Rapid deposition and erosion of coastal deposits can also occur during storms. Level to very gently inclined terrace (7) with locally steep to cliffed terrace scarps. Formed by fluvial deposition of silty sandy clay (8) from the Chapman River on flood plains and in valleys between the adjacent escarpments. Lateral equivalent of the Greenough Alluvium System downstream to the southwest, and derived from the surrounding Moresby System. Dominantly used for agriculture, with no urban or industrial development. Much of the native vegetation has been cleared, except in river channels. Heavy rainfall can cause local flooding in level, poorly drained areas, and severe channel erosion in the river and streams. Level plain with locally steep to cliffed terrace slopes (5). Formed by fluvial deposition from the Greenough and Chapman rivers on flood plains between the dunes and inland escarpment. Dominantly red silty sandy clay over sandy gravel (6), interbedded in places with residual sand and calcarenite of the Spearwood System. Rare swamps with waterlogged organic soil. Overlain by the Quindalup System to the west. Interbedded with the Spearwood System. Lateral equivalent of the Greenough System, and partially sourced from the Moresby System to the north and east. Dominantly used for agriculture and horticulture, with some urban and industrial development. Almost all native vegetation has been cleared, except in river channels and poorly drained areas. Major flooding hazard in level, poorly drained areas, with severe erosion of stream channels also possible. Mostly level to gently inclined dunes, with rare steep to precipitous rocky slopes (9). Dominantly eolian deflated dunes and swales formed by southerly winds and eroded by coastal processes to form a westerly facing scarp. Rare marine facies of biogenic reef near the coast. Forms low sandy rises in the Greenough Alluvium System. Originally calcareous dune sand, now weathered by surface leaching and groundwater precipitation to form yellow (10) and red residual quartz sand over a white to light brown calcrete surface to the underlying calcarenite (limestone). Swampy swales contain waterlogged organic soil. Calcareous slopewash colluvium on the westerly facing footslopes to the scarp is derived from weathered calcarenite. Component of the reefs in offshore areas. Overlain by the Quindalup System to the west. Overlies the Moresby System on the hills to the north and east. Interbedded with the Greenough Alluvium System. Source of construction limestone, building sand, and fill for reclamation. Extensively cleared for cropping and grazing. Areas underlain by limestone are often uncleared. Also used for urban and industrial development. Minor hazard on rocky slopes. Very gently inclined hillcrests above locally steep to very steep scarps. Moderate to steeply inclined sideslopes and level to gently inclined footslopes (11). Residual quartz sand and ferruginous duricrust over mottled soil (weathered rock) on hillcrests (12). Mass wasting deposits ranging from proximal weathered rock debris, gravel, and boulders, to distal silty sand over mottled sandy clay. Seasonally active fluvial deposition of silty sandy clay on sideslopes and footslopes. Hillcrests and plateaus, locally above a scarp exposing weathered Jurassic sedimentary rocks. Minor exposures of Triassic strata and Proterozoic basement rocks on hillslopes. Overlain locally by the Spearwood System. Source of material for the Greenough and Greenough Alluvium systems to the southwest. Mostly cleared for cropping and grazing, but the steeper sideslopes and some gravelly flat tops are only partially cleared of native vegetation. Source of gravel for road building. Heavy rainfall can cause severe channel erosion in the streams, and landslides on the steeper slopes. Cemented ferruginous pisolitic duricrust cappings on low hills and escarpments, locally concealed by residual quartz sand. Potential source of aggregate for road construction. Calcrete and calcarenite (limestone) formed by weathering of carbonate-rich sand dunes. Rock strength varies from moderately weak to very strong, and may be excavated as aggregate or boulders. Overlain by variable thickness of yellow and red sand. Limestone may be used for road base, large-scale fill, harbour installations, and sand for building. Mostly unlithified shell-rich sand of eolian and marine origin, with calcium carbonate contents up to 94%. May be suitable for agricultural applications. Quartz-rich eolian sand formed as a weathered residuum over limestone. Potential source of sand for building platforms and construction.

Reef or rock flat; undivided eolian calcarenite, biogenic reef, and beach rock The Geraldton Regolith-Landform Resources map provides information on the regolith (soils) and underlying rocks, on the landforms (landscape), topography, infrastructure, and on the mineral and construction material resources of Geraldton. This map will be of value in landuse planning, the sustainable development of resources, and in identifying natural hazards, both onshore and in shallow nearshore areas. The map also delineates land systems, which are areas of discrete recurring patterns of landform, regolith, materials, and vegetation. These patterns are related to geological and hydrogeological units, and form the basis of identifying landuse including mineral resource potential. Fluvial sediments ranging from silty clay to sandy gravel. Potential source of aggregate-quality sand and gravel for building and fill. Includes clay suitable for brick-making Mostly colluvial sand, gravel, and clay, with some weathered rock or offshore deep water sand plain Limesand.......................................................................................................

Eolian processes dominant, with wave action important for erosion and deposition in the narrow coastal zone. Dunes and swales formed by southerly winds and eroded by coastal processes to form a westerly facing shoreline. Actively eroding to form blowouts in areas of vegetation loss (3). Includes older deflated dunefields composed of weakly lithified calcarenite (4). Small swampy swales contain waterlogged organic soil. Currently active system that overlies the Greenough Alluvium and Spearwood Systems. Landuses include urban and industrial development, and recreation. Crop cultivation and grazing on the older dunes. Source of limesand, limestone, and sand for construction and beach restoration. Used as fill for reclamation. Migrating sand from blowouts is a minor hazard. DEPARTMENT OF MINERALS AND ENERGY L. C.

Offshore level seabed, and nearshore level to gently inclined seabed, with low, submerged rocky ridges or reefs. Inshore rock platforms (1) and gently inclined shore face. Erosion and deposition by marine tides, currents, and wave action. Small areas of man-made reclamation in urban areas at the coast (2). Dominantly shell and quartz sand formed by biogenic processes, reworking of fluvially sourced material from weathered hinterland rocks, or by erosion of reefs. Reefs or rock flats composed predominantly of eolian calcarenite. Currently active system that includes undivided older reefs probably of the Spearwood System. Primarily used for shipping, fishing industry, and recreation. Possible source of sand or limestone for construction, beach rebuilding, and reclamation. Shallow reefs are a hazard to shipping. Rapid deposition and erosion of coastal deposits can also occur during storms.

Level to very gently inclined terrace (7) with locally steep to cliffed terrace scarps. Formed by fluvial deposition of silty sandy clay (8) from the Chapman River on flood plains and in valleys between the adjacent escarpments. Lateral equivalent of the Greenough Alluvium System downstream to the southwest, and derived from the surrounding Moresby System. Dominantly used for agriculture, with no urban or industrial development. Much of the native vegetation has been cleared, except in river channels. Heavy rainfall can cause local flooding in level, poorly drained areas, and severe channel erosion in the river and streams.

Level plain with locally steep to cliffed terrace slopes (5). Formed by fluvial deposition from the Greenough and Chapman rivers on flood plains between the dunes and inland escarpment. Dominantly red silty sandy clay over sandy gravel (6), interbedded in places with residual sand and calcarenite of the Spearwood System. Rare swamps with waterlogged organic soil. Overlain by the Quindalup System to the west. Interbedded with the Spearwood System. Lateral equivalent of the Greenough System, and partially sourced from the Moresby System to the north and east. Dominantly used for agriculture and horticulture, with some urban and industrial development. Almost all native vegetation has been cleared, except in river channels and poorly drained areas. Major flooding hazard in level, poorly drained areas, with severe erosion of stream channels also possible.

Mostly level to gently inclined dunes, with rare steep to precipitous rocky slopes (9). Dominantly eolian deflated dunes and swales formed by southerly winds and eroded by coastal processes to form a westerly facing scarp. Rare marine facies of biogenic reef near the coast. Forms low sandy rises in the Greenough Alluvium System. Originally calcareous dune sand, now weathered by surface leaching and groundwater precipitation to form yellow (10) and red residual quartz sand over a white to light brown calcrete surface to the underlying calcarenite (limestone). Swampy swales contain waterlogged organic soil. Calcareous slopewash colluvium on the westerly facing footslopes to the scarp is derived from weathered calcarenite. Component of the reefs in offshore areas. Overlain by the Quindalup System to the west. Overlies the Moresby System on the hills to the north and east. Interbedded with the Greenough Alluvium System. Source of construction limestone, building sand, and fill for reclamation. Extensively cleared for cropping and grazing. Areas underlain by limestone are often uncleared. Also used for urban and industrial development. Minor hazard on rocky slopes.

Very gently inclined hillcrests above locally steep to very steep scarps. Moderate to steeply inclined sideslopes and level to gently inclined footslopes (11). Residual quartz sand and ferruginous duricrust over mottled soil (weathered rock) on hillcrests (12). Mass wasting deposits ranging from proximal weathered rock debris, gravel, and boulders, to distal silty sand over mottled sandy clay. Seasonally active fluvial deposition of silty sandy clay on sideslopes and footslopes. Hillcrests and plateaus, locally above a scarp exposing weathered Jurassic sedimentary rocks. Minor exposures of Triassic strata and Proterozoic basement rocks on hillslopes. Overlain locally by the Spearwood System. Source of material for the Greenough and Greenough Alluvium systems to the southwest. Mostly cleared for cropping and grazing, but the steeper sideslopes and some gravelly flat tops are only partially cleared of native vegetation. Source of gravel for road building. Heavy rainfall can cause severe channel erosion in the streams, and landslides on the steeper slopes.

Cemented ferruginous pisolitic duricrust cappings on low hills and escarpments, locally concealed by residual quartz sand. Potential source of aggregate for road construction.

Calcrete and calcarenite (limestone) formed by weathering of carbonate-rich sand dunes. Rock strength varies from moderately weak to very strong, and may be excavated as aggregate or boulders. Overlain by variable thickness of yellow and red sand. Limestone may be used for road base, large-scale fill, harbour installations, and sand for building.

Mostly unlithified shell-rich sand of eolian and marine origin, with calcium carbonate contents up to 94%. May be suitable for agricultural applications.

Quartz-rich eolian sand formed as a weathered residuum over limestone. Potential source of sand for building platforms and construction.

The Geraldton Regolith-Landform Resources map provides information on the regolith (soils) and underlying rocks, on the landforms (landscape), topography, infrastructure, and on the mineral and construction material resources of Geraldton. This map will be of value in landuse planning, the sustainable development of resources, and in identifying natural hazards, both onshore and in shallow nearshore areas. The map also delineates land systems, which are areas of discrete recurring patterns of landform, regolith, materials, and vegetation. These patterns are related to geological and hydrogeological units, and form the basis of identifying landuse including mineral resource potential.

Fluvial sediments ranging from silty clay to sandy gravel. Potential source of aggregate-quality sand and gravel for building and fill. Includes clay suitable for brick-making

Mostly colluvial sand, gravel, and clay, with some weathered rock or offshore deep water sand plain

Mostly gently to moderately inclined dunes, occasionally very steep. Eolian processes dominant, with wave action important for erosion and deposition in the narrow coastal zone. Dunes and swales formed by southerly winds and eroded by coastal processes to form a westerly facing shoreline. Actively eroding to form blowouts in areas of vegetation loss (3). Includes older deflated dunefields composed of weakly lithified calcarenite (4). Small swampy swales contain waterlogged organic soil. Currently active system that overlies the Greenough Alluvium and Spearwood Systems. Landuses include urban and industrial development, and recreation. Crop cultivation and grazing on the older dunes. Source of limesand, limestone, and sand for construction and beach restoration. Used as fill for reclamation. Migrating sand from blowouts is a minor hazard.
