i would not imagine you could use carbon dating, so how do they date amber?

I don't know - when I asked her, she didn't want to go out with me....

It seems that radio-carbon dating can be used..

Amber is a petrified (= densified) resin from trees, it is still an organic compound containing carbon.  Carbon dating is definitely possible !

Radio carbon dating can not be used on "older rocks" i can't remember the exact age but anything older than a couple of Ma is not possible. the only methods u could use would be to a) get a rough evolutionary age from any insects etc trapped in the amber or b) dating the surrounding sediment in which the amber is found either by magnetostratigraphy or biostratigraphy...

This C14 website states that radio-carbon dating can be achieved up to -75,000 years, but obviously depends on the lab, and the degree of precision required. Normally up to 50 - 60,000 years is the limit.

No idea what happens for dating before this though. Is it radiometric?

Most often, amber is dated by dating the matrix rocks - the rock in which it is found. This yields a minimum age. Occasionally it is older than the surrounding rocks because it has eroded from the original deposit and been redeposited. This occurs in some Russian amber. The sediments in which it is found are in deltaic and riverine deposits, where erosion and redeposition is common.

I also enjoy reading the comments, but notice that a lot of people should stay on topic to try and add value to the original blog post.  I would also encourage everyone to bookmark this page to your favorite service to help spread the word.  I'll use this information for my essay topics. If someone is interested in information about cbd oil, then go to the site, there is a lot of useful information.
