Bog Iron Nodules

The images are of freshwater lake iron concentrations (or nodules) that have been historically mined for their iron content, now just scientific curiosities. GTK is investigating whether they may be able to be used for recording environmental changes in Finnish lakes since the last Ice Age (preserving at least 100,000 years of Earth history). Data was used in the MineHeritage project (https://mineheritage-project.eu/) Juankoski leaflet, included in the preview dataset. Preview dataset found at https://doi.org/10.23729/0cb57bd7-1726-4efc-87f4-fc77b7e2adec . To obtain data, please contact [e-mail] .

本数据集的图像为淡水湖中的铁富集物（或称铁结核），这类物质历史上曾因含铁量被开采，如今仅作为科学研究的珍稀样本。芬兰地质调查局（GTK）正开展相关研究，以探究这类物质是否可用于记录芬兰湖泊自末次冰期以来的环境变化——其本身已保存了至少10万年的地球历史记录。该数据曾应用于矿山遗产项目（MineHeritage project，https://mineheritage-project.eu/）的荣科斯基宣传手册，并已纳入本次预览数据集。预览数据集可通过以下链接获取：https://doi.org/10.23729/0cb57bd7-1726-4efc-87f4-fc77b7e2adec。如需获取完整数据集，请发送邮件至[e-mail]联系。
