Production rate variation and changes in sedimentation rate of marine core dated with meteoric 10Be and 14C

10Be Exposure Age Dating of Moraine Boulders and Glacially Polished Bedrock Surfaces in Karakoram and Ladakh Ranges, NW Himalaya: Implications in Quaternary Glaciation Studies

“…500 μl of 9 Be carrier (Be concentration of 982 μg/g) was added to the purified quartz grains, and the sample was dissolved by sequential treatment with concentrated HF/HNO 3 solution and aqua regia. Finally, the sample was dissolved in 6N HCl and was processed with a two‐step column chromatography procedure to isolate beryllium from other ions (Jena et al., 2021, Jena, Bhushan, Ajay, et al., 2022; Jena, Bhushan, Ajay, Dabhi, et al., 2023). Beryllium (in the form of Be(OH) 2 ) was precipitated at a higher pH, and the precipitate was heated at 650°C for 6 hr in order to convert it into beryllium oxide (BeO).…”

Characterization of meteoric 10Be in certified reference materials for use in internal control standards

“…A two-step leaching process will be used to extract and purify meteoric 10 Be adhered to the particle surface of the certified reference materials. The procedure was based on that reported by Padilla [17] and Jena [18]. Figure 1 shows a diagram with the outline of the method used.…”

“…Figure 1 shows a diagram with the outline of the method used. The leaching process results from optimizing the processes presented by Padilla [17] and Jena [18]. In contrast, the radiochemical process has been used in our laboratory based on the analyses presented by Padilla [3].…”

“…1 Scheme for separation and extraction of Be. The leaching of the sample is a mixture of those reported by Padilla[17] and Jena[18]; while the radiochemical extraction process is based on what was established by Padilla[3]…”
