    Definition

    Event and accumulation dates are density estimates of the occupation -and duration of an archaeological site (L. -Bellanger, Husi, and Tomassone 2006; L. Bellanger, Tomassone, and Husi -2008; Lise Bellanger and Husi 2012).

    +and duration of an archaeological site (Bellanger, Husi and Tomassone +2006; Bellanger, Tomassone and Husi 2008; Bellanger and Husi 2012).

    The event date is an estimation of the terminus post-quem of an archaeological assemblage. The accumulation date represents the -“chronological profile” of the assemblage. According to Lise Bellanger and Husi (2012), accumulation -date can be interpreted “at best […] as a formation process reflecting -the duration or succession of events on the scale of archaeological -time, and at worst, as imprecise dating due to contamination of the -context by residual or intrusive material.” In other words, accumulation -dates estimate occurrence of archaeological events and rhythms of the -long term.
