Archaeological Stratigraphy 2D: Unveiling Layers Through Time

What Stratigraphy Is

Stratigraphy is a branch of geology that deals with the study of rock layers (strata) and their sequence. In archaeology, it refers to the systematic analysis of soil or sedimentary deposits to understand past human activities.

The primary tool in stratigraphic analysis is the Law of Superposition, which states that in undisturbed sequences of strata, the oldest layer is at the bottom and each successive layer is younger.

Principles Governing Stratigraphy

The Principle of Cross-Cutting Relations helps identify relative ages of geological features. If one feature cuts across another, it formed after the feature it intersects.

These principles are crucial for archaeologists to reconstruct past events and understand site formation processes.

Real-World Applications

Archaeologists use stratigraphic analysis to date artifacts and structures by correlating them with layers of soil or sediment.

Understanding these principles helps in interpreting complex sites, such as those with multiple periods of occupation or disturbances.

Practical Examples

For instance, a burial pit that cuts through older layers indicates it is younger than the layers it intersects.

Similarly, if an artifact is found within a layer, it can be dated based on the age of that layer.
