| Basalt | Dark fine-grained volcanic rock |
| Calcrete | Surface layer of rubbly or sheet limestone up to 2m thick, common throughout South Australia |
| Clay | Natural plastic clay deposits deposited as sediment (minerals for refractory bricks, e.g. sillimanite or fire clay, industrial minerals) - Includes white and red plastic clay |
| Dolerite | Dark, medium-grained igneous rock |
| Dolomite | Sedimentary rock containing greater than 50% of the mineral dolomite (calcium magnesium carbonate) |
| Gabbro | Dark coarse-grained igneous rock; includes norite (Black Granite from Black Hill) |
| Gneiss | Banded or foliated metamorphic rock, usually of the same composition as granite |
| Granite | Coarse-grained light-coloured igneous rock consisting chiefly of quartz, feldspar and mica |
| Gravel (natural) | Creek or river gravel including buried deposits |
| Ironstone | Lateritic soils and ironstone cappings |
| Limestone | Sedimentary rock containing greater than 50% of the mineral calcite (calcium carbonate) |
| Marble | Metamorphic rock formed by alteration of limestone or dolomite |
| Pegmatite | Coarse-grained light-coloured crystalline rock composed chiefly of minerals found in granite |
| Quartzite | Rock formed from the metamorphism of sandstone |
| Rhyolite | Fine-grained volcanic rock similar to granite in composition |
| Sand | Mortar, plaster and bricklaying sand; concrete sand; general filling, garden sand, paving and landscaping sand, loam; specification filling sand for pipeline trenches etc; road and track construction sand |
| Sandstone | Sedimentary rock containing sand-sized particles mainly quartz |
| Schist | Medium-grained to coarse-grained metamorphic rock composed of laminated layers of micas |
| Shale | Fine-grained sedimentary rock composed mainly of clay-sized particles that is easily split into thin layers |
| Shale-coloured | Red-firing or other darker coloured-firing weathered shale |
| Shale-white | White or cream, pale-firing weathered shale |
| Shell grit | Sand made up on shell fragments |
| Silttone | Sedimentary rock composed mainly of silt-sized particle) that is not easily split into thin layers; they are intermediate between sandstones and shales |
