    Mulu Borneo stalagmite SC02 U/Th dating and oxygen and carbon stable isotopes, 19.5-10.7 ky BP (2022)

    Description: Here are presented Mulu, Borneo (4°6'N, 114°53'E) Secret Cave stalagmite SC02 d18O and d13C values over Termination 1, published in Buckingham et al. (2022). U-Th ages were calculated using the initial detrital 230Th/232Th value of 111 ± 41 ppm, which was previously calculated for SC02 based on two isochrons measured in separate stalagmites from Secret Cave in Mulu (Carolin et al., 2013). A Matlab Monte Carlo script was used to calculated the absolute age and age errors associated with each U-Th sample using the 234U and 230Th half lives presented in Cheng et al. (2013). The Poisson-process deposition model feature in OxCal(v4.4) was used to interpolate between the eighteen U/Th ages to produce an age model (Bronk Ramsey, 2008; Bronk Ramsey and Lee, 2013). This study reports a d18O and d13C record for the portion of SC02 104.1 to 182.4 mm distance from top of stalagmite. The d18O record spans the full deglaciation, and reveals for the first time distinct d18O variations connected with the Bølling-Allerød onset and the Younger Dryas event.

    (Table 1) Sr and S isotope compositions of marine barites from ODP Hole 123-765C (2000)
    PANGAEA
    Details
    Publication Date: 2024-01-09
    Description: Barite can precipitate in microenvironments in the water column (marine barite), from supersaturated pore fluids at the oxic-anoxic boundary within marine sediments and where Ba-rich pore fluids are expelled and come into contact with sulfate-rich seawater (diagenetic barite), or from hydrothermal solutions (hydrothermal barite). Barite is relatively resistant to alteration after burial and has been used in paleoceanographic studies to reconstruct seawater chemistry and productivity through time. For such applications it is very important to determine the origin of the barite used, because both diagenetic and hydrothermal barite deposits may not accurately record the open-ocean contemporaneous seawater chemistry and productivity. We show here that it is possible to distinguish between the different types of barite by using Sr and S isotopes along with crystal morphology and size characteristics.

    Borneo stalagmite SC02 temperature reconstructions over Termination I by the means of fluid inclusion microthermometry (2022)
    PANGAEA
    Details
    Publication Date: 2024-03-25
    Description: This dataset presents cave temperatures over the last glacial termination from stalagmite SC02 from Secret Cave in Mulu, Northern Borneo (4.063°N, 114.833°E). The temperatures are derived by the means of fluid inclusion microthermometry and published in Løland et al., (2022). The study shows that the cave temperature increased by 4.4 ± 0.3 °C (2 SEM) from the Last Glacial Maximum to the Holocene, amounting to 3.6 ± 0.3 °C (2 SEM) when correcting for sea-level induced cave altitude change. Included in the dataset are also the calculated dripwater delta-18O values.
