This finding provides a new horizon for global and regional correlation of continental archives. Additionally, our VADM-predicted<span>&nbsp;</span>¹⁰Be production confirms and further strengthens a common global cause (geomagnetic field intensity) for the change in atmospheric<span>&nbsp;</span>¹⁰Be over the last 50 ka. We also show that most of the<span>&nbsp;</span>¹⁰Be inventory to the lake has been provided by riverine input, but with a significant addition from direct precipitation and dust-aerosol fallout. We estimate a higher dust-aerosol contribution of<span>&nbsp;</span>¹⁰Be during the Holocene and interstadial stage 3 (22–50 ka) as compared with the glacial period (12–22 ka).</p></div></div> application/pdf 10.1029/1999GL900469 en American Geophysical Union Linking the10Be continental record of Lake Baikal to marine and ice archives of the last 50 ka: Implication for the global dust-aerosol input article
