Subclass of:

• crmsci:S17 Physical Genesis
• crmarc:A5 Stratigraphic Modification

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, or transformation/modification occurring on a particular site throughout a particular period of time. These processes are usually not only due 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.

Examples:

the production of the deposits L14-L18 and L22-L24 by at least seven (7) distinct fill episodes of a neolithic ditch, observed at the northern section of Trenches 6 and 21, at the site Paliambela, Kolindros–see Figure 10

the creation of the one-meter-thick level of pumice caused by the Minoan eruption of Thera and consisting of five distinct layers, which covers the ruins at the excavation Akrotiri, Thera –see Figure 9 (Doumas et al., 2015)

the creation of the 8-10-metre-thick level of successive layers volcanic ash deposed on top of the one-meter-thick level of pumice, which covers the ruins at the excavation Akrotiri, Thera—see Figure 9 (Doumas et al., 2015)

the production of the stratigraphic interface “[3]” by the cut in the pre-existing strata of the posthole –see Figure 6

the production of the stratigraphic unit volume “(18)” via the filling of the posthole with detritus or some other matter –see Figure 6

In First Order Logic:

• A4(x) ⇒ S17(x)
• A4(x) ⇒ A5(x)

Outgoing properties:

• crmarc:AP7 produced (was produced by) (0,1:0,n) → crmarc:A8 Stratigraphic Unit
• crmarc:AP9 took matter from (provided matter to) (0,1:0,n) → crmsci:S10 Material Substantial
