| 英文摘要 | Application of X-ray fluorescence core-scanning (XRF-CS) on both marine and lake sediments has achieved remarkable results. However, its application has not been widely extended to the research on speleothems. In this study, we measure the Sr abundance and the Sr/Ca ratios of three stalagmites (two aragonite stalagmites, one calcite stalagmite) using the state-of-the-art fourth-generation Avaatech high-resolution XRF core scanner. Through comparisons among different scan paths and among different scan resolutions, as well as comparisons with inductively coupled plasma optical emission spectrometer (ICP-OES), Itrax XRF, and Artax XRF results, we confirm that the Avaatech XRF core scanner could precisely, quickly, and non-destructively analyze the high-resolution Sr abundance of speleothems. Furthermore, we combine the stalagmite O-18 records to explore the paleoclimatic significance of the measured stalagmite Sr/Ca. |
