文摘

The inner structure of varves in the recent sediments of Lake Bele, Khakassia, is studied via X-ray fluorescence microanalysis at the Siberian and Shanghai Centers of Synchrotron Radiation. Similar experimental conditions apply in both cases: excitation energy, 20-2 keV; size of exciting radiation spot, 80-00 μm; scanning step, 100 μm. The dates determined for marking layers coincide. The experimental results shed new light on the geochemistry of sedimentation processes and help estimate the current sedimentation rate.
