Abstract:
Here, we present X-ray fluorescence (SM30 magnetic susceptibility meter, ZHinstruments Inc.) and normalized mass magnetic susceptibility (VANTA VMR with a Silicon Drift Detector, Olympus) datasets of two sediment cores (0.42 and 0.46 m long) from a shallow lake (Suzdalevo Lake, 1.8 ha, max. depth of 2.3 m) located near the epicenter of the Tunguska Event explosion in 1908 CE (60°39′29.05″N, 102°3′3.36″E). The datasets include primary data presented in an article (Kavková et al. 2022) that is focused on formation process of the study site (potential impact lake) and Tunguska Event-related environmental disturbance. Both cores were retrieved using a Kajak gravity corer (sampling tube diameter of 5.8 cm and length of 50 cm) in May 2019.

Comment:
Magnetic susceptibility – X (SI): All sediment samples from both cores were placed into plastic cups and magnetic susceptibility was measured using a SM30 magnetic susceptibility meter (ZHinstruments Inc., Czechia) at an oscillation frequency of 8 kHz and generated magnetic field amplitude of 40 A/m. The magnetic susceptibility values [X (SI), average of three measurements] were mass normalized.
XRF – selected element (Sr, Rb, Ti, P, Si, Zr, Fe, Mn) concentrations (ppm, given in mg/kg): The total content of selected elements in wet sediment was determined by means of X-ray fluorescence (XRF) spectrometry using a handheld ED-XRF analyzer VANTA VMR with a Silicon Drift Detector (Olympus, United States). National Institute of Standards and Technology (NIST) standard reference materials 2711a Montana II Soil and 2710a Montana I Soil were used for quality control.
