Nah, just ignore them.

I just completed reading this book and they analysed an individual ring (Isotopes or some such) to prove a point.

That is the nice thing about tree rings; you have an exact date with which to calibrate other dating methods, as well as the historical record against which to cross-check the tree ring.

"Given that Santorini has been linked to the miracles in Exodus, wonder how this new time line fits in with Biblical scholars?"

Ahem, looks like they'll have to shift the date of the Exodus, huh?

So, you’ve rec’d it, read it, and did like it? :’)

"So, you’ve rec’d it, read it, and did like it? :’)"

Yup. I'm left with one unanswered question though. They said that the 'rims' on the Carolina Bays could only have been formed by the extreme heat from an impact and/or some type acid. Then they go on to say that the Bays were formed by bigs chunks of flying ice. So???

[SunkenCiv]

They side with the impact scenario, in their case the impactors were ejecta from a single, large, northerly impact (more than one, an apparent doublet impact).

[SunkenCiv]

[rimshot!]

Shouldn’t that be the other way around?

Geoarchaeology:
The Earth-Science Approach to Archaeological Interpretation
by George (Rip) Rapp, Jr. and Christopher L. Hill
reprised from here

"Artifacts from Akrotiri, linked to the Egyptian calendar [sic] put the Thera eruption at more than a hundred years later [than 1644 +/- 20 BC]. While the controversy remains open, it is our view that the volcanic activity recorded in the Greenland ice core more likely came from nearby Iceland than from the eastern Mediterranean (this may be testable by any chemical signature). [p 158-159]

"Living samples from a freshwater lake on limestone terrain have been known to give a radiocarbon date of up to 1600 BP." [p 166]

"Living samples from a freshwater lake on limestone terrain have been known to give a radiocarbon date of up to 1600 BP." [p 166]

That is one of the poorest things to use for a radiocarbon date. Freshwater shellfish from limestone environments are equally bad.

There are ways to calibrate those kinds of samples but it is easier to use more reliable materials to start with.

There is a large body of literature on this problem.

The soil of Santorini is enriched in C12, and this has an impact on the RC dating of stuff on the island, including plants grown in the soil (samples from still-living plants having a much higher RC date). Seems like thermoluminescence, electron spin resonance, and perhaps other forms of radiological dating would be a better choice.

Sounds more like the soil, or some components of it, are deficient in C14. I know limestone can do this, but I am not sure how volcanic soils would do the same.

I would be curious to know that the C13/C12 ratio is, as that is often a good indicator of problems with C14, and it reflects on the material you are dating.

This is the kind of thing you have to watch out for in C14 dating.

Normally we date several different materials and compare, when possible, against other dating methods.

[SunkenCiv]

Yes, that was imprecise of me... the soil is deficient in C14.

[Renfield]

Similar techniques used on wood buried beneath volcanic ash allowed Manning and others to date the Santorini volcanic eruption, one of the largest in the last 10,000 years, as most likely occurring in the late 17th century B.C., 100 years earlier than previously believed. This supports Mike Baillie's claim of 1620 BC.
