Synchrotron radiation X-ray fluorescence (SR-XRF) data of Lake Chasha sediment core, Southern Kamchatka

This dataset contains high-resolution elemental concentration data obtained by synchrotron radiation X-ray fluorescence (SR-XRF) core scanning of a sediment core from Lake Chasha (southern Kamchatka, Russia). The dataset includes continuous geochemical profiles for 14 major and trace elements (K, Ca, Ti, Mn, Fe, Cu, Zn, Ga, As, Br, Rb, Sr, Y, Zr) measured in parts per million (ppm) with a resolution of 1 mm.
