ARH305H1 Lecture Notes - Lecture 3: Harris Matrix, Unconformity
Document Summary
Defined as the surfaces of strata" (harris) a conceptual device, really, because the surface of a layer is really part of the layer. Concept of interface also borrowed from geology which recognizes bedding planes (surfaces of strata) and unconformities (major gap in a sequence cause by removal is strata, ex erosion) Type of archaeological interfaces: layer interface former ground surface, horizontal or upstanding, feature interface a surface formed by destruction of pre-existing strata, two types. Vertical feature interface removal of strata ex. pit digging: period interface (bedding plane) sum total of layer and feature interfaces, which were, ground surfaces at same time. Sealed deposit one in which you can rely on the stratigraphic position based on the cultural layer you find it because it has been sealed by natural levels above and below it. Phasing - the process of creating a sequence of all strata and interfaces (harris. This should be done on basis of stratigraphic information alone.
