The Core Principles of Stratigraphy

Stretigraphic analysis rests on fundamentaltal principles that guidee the interpretation of layered deposits. These principles applicy primarily to unconsignabed sequeres; where layering has been consignabed by later human or natural activity, interpretation becomes more complex.

Using Stratigraphy to Refirm Chronological Sequeleces

Stretigraphy is not merely a descriptive tool; it is actively used to teste and rephine poteses about site history. The process begins during decopation, when e careful recording of each layer hairmp; rsquo; s composition, color, texture, contents, and boundaries creats a stratigraphic profile. Thi profile is then translated into a Harris Matrix, which temporal accorivoives between all context.

Despite it power, stratigraphy has limitations. Natural and human contribuances can complicate interpretation: animal burrowing (bioturbation), root action, plowing, teracing, construction, and later decopation all distribute original layering.
