| Scale | Field analysis |
| Questions | Can help to identify a deposit’s parent materials and provides a means to compare the composition of different deposits. Also used in the identification of post-depositional transformations such as gleying (waterlogging). |
| Time and cost | Very quick and low cost |
| General comments | A standard part of most context records. |
Soil colour is a product of the parent materials of the deposit as affected by post-depositional processes.
[edit] Questions
Soil colour is one of the main ways by which excavators differentiate between different depositional contexts. Soil colour is a product of the materials that make up a deposit (both natural and anthropogenic) but these can then be transformed by the effects of post-depositional processes such as gleying (waterlogging) and podzolisation (movement of organic matter and iron through the profile). Understanding the origin of the soil colour therefore is vital to the interpretation of site formation and post-depositional processes.
