Thanks to Dr. Gary Hurd for pointing out this article to me over at TWeb. A little background to the article first ...
I have been told that Lake Suigetsu gives strong evidence that the earth is old. You can read the conventional story many places on the web. But I have lodged objections to this from several angles, two of them being ... 1) I'm not sure the Carbon-14 testing of the macro fossils involves proper assumptions, and 2) the "29cm flocculent layer" on top of the sampled mud seems to pose a serious problem to the "40,000 year placid deposition" theory. Why would the alternating sequence continue for almost 40,000 years, then stop 300 years ago? Why wouldn't it have stopped at other points in the 40,000 years? I won't comment on the first objection here because I have been unable to get detailed answers (but I'm close ... I think Dr. Kirk Bertsche is interested in answering my questions soon over at TWeb)
Here's the key Suigetsu paper (1998) from the archives of the journal
Radiocarbon (free) ...

Here's the original Kitagawa paper (1995) that mentions the 29cm flocculent layer ...
And here's the article Dr. Hurd pointed out to me with some key extracts ...
I hate to sound like a stuck record, but creationists have been saying that mainstream geologists need to reevaluate large portions (like, the entire thing) of the geologic record for many years. Henry Morris has been the most prominent of these with his landmark book in 1961,
The Genesis Flood. All of you should read it.
How does this relate to Lake Suigetsu? It provides support to the creationist idea that the Suigetsu "varves" do not represent annual deposition at all, but rather represent rhythmites, i.e. from rapid deposition. And the flocculent 29cm at the top of the sediment is exactly what we would expect if these sediments were laid quickly, rather than gradually over 40,000 years.
Comments anyone?
