Chronometric dating technique
Chronometric dating technique - reviews of senior online dating sites
The date we get will be the date that that particular tree was cut down.However, if wood was recycled for subsequent building construction, the date we get will actually be earlier than the date the last building was constructed.
So the date will be stated, as say, 1145 years old or - 50 years.Many of these methods use what is referred to as a 'molecular clock'. The rate at which one element breaks down into another is referred to as the HALF LIFE of that element.That is to say, a molecular process that happens at a regular and predictable rate. The half life is the time it takes for half of the sample to break down. So in a sample of C14, half of it will break down in 5,730 years.CHRONOMETRIC DATING, also called Absolute Dating, makes use of methods that yield a date or date range for an object.Rather than just indicating if something is older or younger than something else, we get an actual time period as a result.That means, to use this method, we must have a known tree ring sequence for a particular species of tree in a particular climatic region.
We cannot, for example get a date for a oak tree sample in California using a tree ring sequence for maple trees from Belgium.
Unlike the molecular dating methods, for dendochronology we get a single year date.
Tree ring dating has also been used to confirm and calibrate carbon 14 dates.
That means that the play was without fail written after (in Latin, post) 1587.
The same inductive mechanism is applied in archaeology, geology and paleontology, by many ways.
The short half life of C14 allows us to use this method to date recent historic sites to sites that are 120,000 years old.
