    Penultimate deglacial sea-level timing from uranium/thorium dating of Tahitian corals. by Thomas, A, Henderson, G, Deschamps, P, Yokoyama, Y, Mason, A, Bard, E, Hamelin, B, Durand, N, Camoin, G

    Published 2009
    “…We found, by means of uranium/thorium dating of fossil corals, that sea level during the penultimate deglaciation had risen to ~85 meters below the present sea level by 137,000 years ago, and that it fluctuated on a millennial time scale during deglaciation. …”

    Chronology of heterogeneous deposits in the side entrance of Postojna Cave, Slovenia by Mateja Ferk, Matej Lipar, Andrej Šmuc, Russell N. Drysdale, Jian Zhao

    Published 2019-01-01
    “…The time of the flowstone deposition was determined by radiocarbon and uranium-thorium dating techniques. The results yielded three distinctive age groups of flowstone facies of 33 ka, 103 ka and 153 ka. …”

    DNA, spectroscopic and geochemical analyses of bone fragments and associated speleothems in Postojna cave, Slovenia by Matej Lipar, Irena Zupanič Pajnič, Marko Cotman, Jelka Zabavnik Piano, Jian-xin Zhao, Dean Pekarovič, Tamara Leskovar

    Published 2020-12-01
    “…However, we succeeded in amplifying a 94 bp long fragment of the cytochrome b (Cyt b) gene of mitochondrial DNA (mtDNA) in polymerase chain reaction (PCR) for one sample, and in sequencing the amto that of the Cyt b of the cave bear (Ursus deningeri or Ursus spelaeus sensu lato). The uranium-thorium dating of the speleothem covering the bones revealed its thanatocoenosis occurred prior to 55 ka, most likely in the late marine isotope stage 4 or early marine isotope stage 3. …”

    The Asian monsoon over the past 640,000 years and ice age terminations by Cheng, Hai, Edwards, R. Lawrence, Sinha, Ashish, Spötl, Christoph, Yi, Liang, Chen, Shitao, Kelly, Megan, Kathayat, Gayatri, Wang, Xianfeng, Li, Xianglei, Kong, Xinggong, Wang, Yongjin, Ning, Youfeng, Zhang, Haiwei

    Published 2020
    “…Here, using our new speleothem data, we extend the Chinese record to cover the full uranium/thorium dating range, that is, the past 640,000 years. …”

    Hydroclimate changes across the Amazon lowlands over the past 45,000 years by Lawrence Edwards, R., Auler, Augusto S., Cheng, Hai, Kong, Xinggong, Wang, Yongjin, Cruz, Francisco W., Dorale, Jeffrey A., Chiang, Hong-Wei, Wang, Xianfeng

    Published 2018
    “…Our results are based on a decadally resolved, uranium/thorium-dated, oxygen isotopic record for much of the past 45,000 years, obtained using speleothems from Paraíso Cave in eastern Amazonia; we interpret the record as being broadly related to precipitation. …”
