Talk:Radiometric dating
From Wikipedia, the free encyclopedia
[edit] Sr -- Sm
The list of radiometric dating technics at the end of the article includes
- samarium-neodymium (Sr/Nd)
- samarium-yttrium (Sr/Y)
Both items begin with samarium (Sm), but the chemical symbol shown is that of strontium (Sr) instead of samarium. I'd fix it, but I don't know what was intended. Mike Sarles
- Fixed that (one was a duplicate) and removed the following for clarification and/or verification:
-
- strontium-neodymium-hafnium-lead (Sr-Nd-Hf-Pb)
-
- if it's real it can be put back. Vsmith 18:25, 27 August 2006 (UTC)
[edit] "Radiometric" dating?
The section "Short-range dating techniques" in this article contain interesting descriptions concerning various dating methods such as dendrochronology, "varve analysis", "hydration dating" or "obsidian dating", and thermoluminescence.
Strictly speaking, however, those methods do not belong to the topic of Radiometric dating, the current title of this article. Therefore, in my opinion, one of three things should be done: (1) rewrite the section so as not to appear as overtly off-topic; (2) move those other techniques to their proper places and place a link in "See also" section; or (3) rename the article to reflect a more general topic such as "Dating techniques" or the like. What do others think about this? --HYC 21:32, 8 September 2006 (UTC)
- Moved three paragraphs to Incremental dating, which was a stub needing more info. Vsmith 22:17, 8 September 2006 (UTC)
Sorry. My fault. I thought U/U, Sr/Nd, Sr-Nd-Pb were radiometric datings but on further research I see they are isotope ratios. Valich 21:15, 10 September 2006 (UTC)
