Description
ARCH 100 Lecture 2 Chronology: trying to figure out the “When” Relative Dating: • archeological objects are arranged in an older – to young relationship Ex) object A is younger than object B Seriation: based on style, method where assemblages or artefacts from numerous sites in the sae culture, are placed in chronological order • Assume that it will change over time • Ex) ipod, eventually these changes (we can put that in chronology) • Bell curve of popularity: popularity of that style increases when everyone has that style • Stylistic change and date corresponds • Change for preferences with music format – textbook preference • When you don’t have the corresponding date, figure out what is most basic, utilitarian version (제제 제제제제 제제 제제제제제제제제) = pot B from the slide - Pot B is wide and simple, very utilitarian - Pot C is still large with clear handle etc - Try to figure out from the earliest to the latest - One interpretation of it, cannot be accurate SITE AAND SITE B • Get some kind of idea with the other site that has similar types of artefacts • Site A, blue pottery has a date, and Site B has a blue pottery which can be put in same date Stratigraphy Law of Superposition • each layer is younger than the layer beneath it - items found in the same layer are associated with each other - Stratigraphy on archaeological sites Fun trio (Fluorine, Uranium, Nitrogen) – Natural elements in soil • Gives relevant date from teeth, bones from same site (find out which bones are older and younger) • The longer bones, or other things are in the ground, the more FUN will be absorbed • Bottom of the file, take a fluorine sample of lowest and the highest sample, and figure out whether it is from the same date or not Absolute Dating (Chronometirc) : gives date, calendar date or scientific date with age range BP- before present(1950) BC/AD - (year “1” is arbitrary) BC – add 2000 years old BCE – before the common era Radiocarbon/dendrochronology: AMS (accelerator mass spectrometry ) Radiocarbon (C14) • Naturally occurring carbon isotope • Absorbed from atmosphere • Dates charcoal, bone, wood, other organic material • Age range – up to 40,000 years ago (potentially up to 70,000 years) • Half life – 5730 +- 40
