3/ Our results give also insight towards interpretation of speleothem isotope records.
If you have dirty and seemingly ’undatable‘ speleothem samples in your lab - look no further! Isothermal Thermoluminescence (ITL) dating can help you ! Look at our latest study led by Junjie Zhang & Sumiko Tsukamoto of #LIAG#TuebingenUnieur02.safelinks.protection.outlook.com?url=https%3A...
So, what you're saying is that this speleothem constitutes hard evidence of cyclical perturbations.
Also it turned out this particular speleothem contains the climate history of the region it grew in for the entire Holocene 🤩
The inferred temperatures suggest it did form during an interglacial period. Speleothem records in Japan are not common, so it is good to see that work is being done to collect them.
Sakai et al present a speleothem record from the Middle Pleistocene from Nara, Japan. The speleothem is at least 460 thousand years old. A more precise age is not possible to deduce, since it is at the limit of the U-Th dating method. ⚒️🧪🌊 geoscienceletters.springeropen.com/articles/10....
Stalagmites are useful archives in reconstructing paleoclimates: most paleoclimate studies used stalagmites that are distributed in specific locations and ages. We examined a stalagmite (GYM-1) collec...
Wilcox et al present a climate proxy record from MIS 5c (106-93 thousand years ago) from a speleothem in southern Alaska. The temperature reconstruction indicates that the temperatures were similar to present during this period, despite being an interstadial ⚒️ onlinelibrary.wiley.com/doi/full/10....
