Analysis
can be of colour and texture differences. These differences indicate differences
in formation processes. Formation processes may be cultural (c- transforms)
or natural (n-transforms). A c-transform is defined as the deliberate or accidental
activities of humans. It is important, in analysis, to determine the possible
formation process. This profile provides us with evidence of both n-transforms,
such as the animal hole on the left of the image, as well as c-transforms, such
as the floor features that run horizontally from the left. |

Stratification
is the layers of cultural or natural debris visible in the side of any excavation
unit. A profile showing a series of layers is a sequence that has accumulated
through time. Stratigraphic deposits conform to the law of superposition, meaning
that where one layer overlies another, the lower layer was deposited first.
This is true only where no disturbance has occured. In circumstances where soil
has been excavated and reinterred, the layers may no longer represent sequential
deposits over time. Undisturbed stratification can be a useful tool in relative
dating. |
