ANTH 112 Lecture Notes - Lecture 24: Frequentist Probability, Luminescence, Dendrochronology
Document Summary
January 20th 2015: k, tree ring daing (11 000 bp present) You can match ring size and color to igure out the years (depends on temperature and precipitaion of those years) Allows for paleo environmental data to be collected. You only know when the tree was cut down, there is no guarantee that you are dealing with a structure that was made during that ime frame: humans reuse wood, carbon14 daing (50 000 bp ad 1500) Calibraion ad 300 100: k-ar daing (5 000 3 billion years ago) Dates rocks, required the principle of associaion (arifacts share dates with the rocks)ranges 100 000 years 500 000 years: thermo luminescence daing (20 000 bp 50 bp) Reheaing potery (clay) releases light that was stored when it hardened over ime: energy is released in the form of light, archaeo-magneic daing. Preservaion of the earth"s magneic north pole in iron rich clay: need to know todays locaion to date clay back, obsidian hydraion.
