Sr-isotope analysis of speleothems by LA-MC-ICP-MS: High temporal resolution and fast data acquisition

LA-MC-ICP-MS 87Sr/86Sr ratios of speleothem MAW-4 against distance from top [mm] for the linescan as well as the spot analyses. For better visualization of the error bars, spot analyses data were shifted to the right by 0.05 mm. Linescan analyses indicate a small increase in 87Sr/86Sr ratios, which was not possible to resolve by spot analyses.113
