What is fractionation when it comes to dating
Shellfish obtain carbon for shell building from two sources.
Let’s investigate more on how the technique came about…
According to Morton (19), this comprises an outer layer of quinone-tanned protein (periostracum), a columnar crystalline layer usually consisting of either calcite or aragonite, and an inner, nacreous layer of thin crystalline sheets.
The calcium carbonate, which is the inorganic fraction of the shell, is the most often used fraction in radiocarbon dating shell because it is largest.
The technique was invented by two veterans in the underground seduction community known only by their pseudonyms, IN10SE and Swingcat.
These two characters first received some limelight inside Neil Strauss’ book (where they were described under different pseudonyms).
