Carbon dating information
by Helen Fryman Question: What about radiocarbon dating? Response: I asked several people who know about this field. (1.) C14 dating is very accurate for wood used up to about 4,000 years ago.
And this big sequence is then used to 'correct' C14 dates. (3.) Even if the rate of decay is constant, without a knowledge of the exact ratio of C12 to C14 in the initial sample, the dating technique is still subject to question.
(4.) Traditional 14C testing assumes equilibrium in the rate of formation and the rate of decay.
This calendar, with the months January through December, is a business standard used in many places round the world to define the year: one which hearkens back to Christian and Roman Imperial precedents.
But other timekeeping methods exist and are still used in the modern world, circumventing the easy processing of dates and history between cultures.
(They conveniently forget to mention that the tree ring chronology was arranged by C14 dating.
The scientists who were trying to build the chronology found the tree rings so ambiguous that they could not decide which rings matched which (using the bristlecone pine).
Throughout history, time has been defined in a variety of ways: by everything from the current ruler, or empire, or not defined at all.
For periods without a historic record, attempts have been made to categorize tool kits, pottery styles, and architectural forms into regional timelines.
So they tested some of the ring sequences by C14 to put the sequences in the 'right' order.
Once they did that they developed the overall sequence.
Example: wood found in a grave of known age by historically reliable documents is the standard for that time for the C14 content.Tags: Adult Dating, affair dating, sex dating
