XRF and magnetic susceptibility records from sediments of Suzdalevo Lake (Tunguska region, Russia) – cores SUZ1 and SUZ3

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.

这里，我们呈现了取自1908年通古斯事件（Tunguska Event）爆炸震中附近一处浅湖（Suzdalevo湖，面积1.8公顷，最大水深2.3米，坐标60°39′29.05″N，102°3′3.36″E）的两根沉积岩芯（sediment cores，长度分别为0.42米和0.46米）的X射线荧光（X-ray fluorescence，使用SM30磁化率仪，ZHinstruments公司）及归一化质量磁化率（normalized mass magnetic susceptibility，使用配备硅漂移探测器（Silicon Drift Detector）的VANTA VMR，奥林巴斯（Olympus））数据集。该数据集包含Kavková等（2022）一文所呈现的原始数据（primary data），该文聚焦于研究区域（潜在撞击湖，potential impact lake）的形成过程（formation process）及与通古斯事件相关的环境扰动（environmental disturbance）。两根岩芯均于2019年5月通过Kajak重力取芯器（Kajak gravity corer，取样管直径5.8厘米、长度50厘米）获取。
