##  [Lithic Reduction Sequence](/lithic-reduction-sequence-0) 

 Definition

The ordered series of knapping stages and technical strategies through which a stone core is systematically transformed into flakes and finished implements, characterized by choices of platform preparation, percussion technique, core management and criteria for flake removal; defined by procedural stages and their material correlates.

 

 

 

 

 

 





## Principle

Principle

Patterns of flake scars, cortex retention, platform morphology and scar chronology encode the sequence of reduction: diagnostic combinations of these attributes map onto particular reduction stages and strategies.

 

 

 

 

 





## Demonstration

Demonstration

Illustrative scenario: A knapper begins with cortical cortex removal (early stage: high cortex percentage on debitage), prepares platforms and performs hard‑hammer blows to produce large flakes (middle stage: prominent bulbs, unifacial scars), then shifts to soft‑hammer or pressure to produce fine thinning flakes and retouch (late stage: small, closely spaced scars and faceted platforms). The assemblage preserves a gradient of cortex, scar size and platform treatment that indicates the reduction sequence.

 

 

 

 

## Misapplication

Misapplication

Assuming that the presence of finished tools alone indicates the full reduction pathway ignores curated tools and off‑site reduction; the semantic error is conflating final tool types with the entire operational history of the core.

 

 

 

 

 





## Consequence

Consequence

Correct analysis reconstructs technological strategies, raw material economy and mobility patterns; incorrect inference can misrepresent site function, raw material investment and skill organization.

 

 

 

 

## Reversal

Reversal

Techniques such as bipolar reduction, bipolar-on-anvil, or intensive resharpening can produce flake attributes similar to different reduction stages, so standard stage‑based attribution must be qualified or supplanted by techno‑morphological context.

 

 

 

 

 





## Boundary

Boundary

Clearly within: sequential sets of debitage and cores showing progressive cortex reduction, changing scar morphology and platform preparation. Boundary case: highly fragmented assemblages where scar sequences are interrupted. Clearly outside: isolated resharpening flakes whose attributes reflect only tool maintenance not primary core reduction.

 

 

 

 

 





## Semantic Tension

Semantic Tension

Tension between reduction sequence and tool use‑life models: reduction sequences record manufacture decisions, while use‑life models emphasize later curation and recycling; both affect flake attributes and must be disentangled.

 

 

 

 

 





## Synthesis

Synthesis

A lithic reduction sequence is both a manufacturing pathway and a behavioral record: it links specific knapping techniques and decisions to the spatial and economic organisation of stone use.
