| The material is unweathered and unconsolidated, making it a prime target for commercial exploitation. |
| Well-preserved, unweathered rocks that crystallized rapidly and have not been subjected to major reheating events are most likely to give valid isochrons. |
| Similarly, there exists the potential for finding ancient samples from Mars or even Venus, as well as unweathered carbonaceous chondrites. |
| They differ from unweathered parent material in their aggregate structure, colour, clay content, carbonate content, or other properties that give some evidence of soil-forming processes. |
| The face that looked back at him was fresh-skinned, unlined, unweathered by life. |
| Typically concentrations in the unweathered material are higher in the C horizon than in the overlying soil horizons. |
