High-resolution XRF analysis of sediment core IZN19-29 from Lake Iznik (NW Turkey)@en

High-resolution XRF analysis of sediment cores (IZN19-05, IZN19-07, IZN19-09, IZN19-11, IZN19-13, IZN19-15, IZN19-20, IZN19-21, IZN19-22, IZN19-23, IZN19-24, IZN19-27, IZN19-28 and IZN19-29) from Lake Iznik, NW Turkey. The relative contents of major and trace elements were analysed with an X-Ray Fluorescence (XRF) Avaatech Core Scanner (EDYTEM Laboratory). The split-core surface was first covered with a 4-μm-thick Ultralene film to avoid contamination and desiccation of the sediment. All cores are registered in the French national cyber-core repository https://www.cybercarotheque.fr and the International Geo Sample Number (IGSN) service https://www.igsn.cnrs.fr/#/search. All cores were collected in April and July, 2019.

本数据集针对土耳其西北部伊兹尼克湖（Lake Iznik）的14根沉积物岩芯（IZN19-05、IZN19-07、IZN19-09、IZN19-11、IZN19-13、IZN19-15、IZN19-20、IZN19-21、IZN19-22、IZN19-23、IZN19-24、IZN19-27、IZN19-28、IZN19-29）开展高分辨率X射线荧光（X-Ray Fluorescence, XRF）分析。本次分析采用EDYTEM实验室的Avaatech XRF岩芯扫描仪，测定了岩芯中常量元素与微量元素的相对含量。为避免沉积物受到污染与脱水，实验人员首先将剖开的岩芯表面覆盖一层厚度为4微米的Ultralene薄膜。所有岩芯数据均已在法国国家数字岩芯库（https://www.cybercarotheque.fr）与国际地质样品编号（International Geo Sample Number, IGSN）服务平台（https://www.igsn.cnrs.fr/#/search）完成备案。所有岩芯均采集于2019年4月与7月。
