Typology Typology is a method that compares reference objects in order to classify them according to their similarity or dissimilarity and link them to a specific context or period.
This technique is frequently used when it is impossible to make use of absolute dating methods; it generally allows archaeologists to identify the period to which a cultural site or object belongs, without specifying the date of occupation.
This is the only type of techniques that can help clarifying the actual age of an object.
These methods usually analyze physicochemical transformation phenomena whose rate are known or can be estimated relatively well.The art is thought to be of considerable antiquity on the basis of still inconclusive evidence of patination, distribution in both Australia and Tasmania, and the absence of SYNONYMS OR RELATED TERMS: percussion method, percussion flaking CATEGORY: lithics DEFINITION: Any of the methods used to strike a flake from a core in the making of stone tools; the reduction of a stone core by hitting it with a hammerstone or bone. Indirect percussion uses a punch between the core and the hammer.Anvil percussion (block on block) is the striking of a core against a fixed hardstone anvil.However, this method is sometimes limited because the reoccupation of an area may require excavation to establish the foundation of a building, for instance, that goes through older layers.In this case, even if the foundation of the building is found in the same stratigraphic level as the previous occupation, the two events are not contemporary.
