A reduction sequence investigates how stone artefacts were made through the identification of different manufacturing stages.
Applying a detailed debitage classification system to define closely the reduction sequence at Jebel Humeima, Coinman reattributes the assemblage to Akhmarian, replacing an earlier Aurignacian attribution, obviously a major realignment, given the dichotomy usually perceived between the two.
The experimental findings allow us to produce the following idealised model of the handaxe reduction sequence at Isampur Quarry:
Although the specific details of the reduction sequence may differ from one feature to another at Giv'at Kipod, several common trajectories for the production of bifacial tools at the site can be discerned.
This kind of reduction sequence is similar on fine-grained stones, even though other methods could easily have been used.
This paper examines stone tool technology from the surface collection of artefacts from Middle Palaeolithic sites in the Kortallayar basin, South India, with emphasis on the lithic reduction sequence.
On the other hand, in level Ja certain chaines operatoires show all the stages of the reduction sequence.
Neeley & Barton, on the other hand, see it as representing facies or stages in a reduction sequence within a context of varying degrees of mobility and related economizing behaviours.
The underlying and more significant question concerns the concept of cobbles--their form and volume, and the ways in which natural features of the raw material may have been incorporated in reduction sequences leading to tool production.
MMI's technical expertise and knowledge of current advances in clinical MRI played a key role in developing the Metal Artifact Reduction Sequences (MARS) that will be used in these studies.
The approach adopted has so far involved analysis of spatially segregated rockshelter deposits, open site surveys and GIS analysis, phytolith analysis, construction of generalised reduction sequences, and stone sourcing studies.
These deposits, bearing witness to a series of climatic degradations, are contained within three principal layers and have permitted the systematic reconstruction of lithic reduction sequences, coupled with a comprehensive spatial analysis of artefact distributions and use-wear.
