Scope note for the class Stratigraphic Genesis – A4  Back

Scope note

This class comprises activities or processes that have produced homogeneous, distinguishable units of stratification that are in a relatively stable form from the time of their genesis until they are observed. Such processes may be the aggregation of cycles of erosion/destruction, deposit/accumulation, transformation/modification occurring on a particular site throughout a particular period of time. These processes are usually due not only to natural forces (i.e., climate, the impact of flora and fauna, other natural events), but also to human activities, in particular, excavation and construction. An event of stratification genesis typically produces two main forms of stratification units both a deposit and an interface.
