Hydrogeological overview Saxony-Anhalt (HyÜK400)

The presentation service for the Hydrogeological Overview of Saxony-Anhalt is being revised and is currently not available (end of Q1 2021). The data level shows areas with different characteristics of the main aquifer. The legend units identify units with different geological properties that influence hydrological properties such as permeability and chemical environment of groundwater. Groups are formed by the overarching structure into loose rock, solid rock and mining main aquifers. The pore aquifers of loose rock comprise 8 stratigraphic and petrographic distinct units. The gap and karst aquifers of the solid rock are divided into 16 units. For the disturbance of the aquifer in areas disturbed by mining, areas with active mining and relocated waste material are distinguished.萨克森-安哈尔特州水文地质概览（Hydrogeological Overview）展示服务目前正在进行修订，暂无法使用，预计恢复时间为2021年第一季度末。 本数据集的数据层级展示了具备不同特征的主要含水层（aquifer）分布区域。图例单元用于标识具有不同地质属性的单元，这些属性会对渗透性、地下水化学环境等水文特性产生影响。依据顶层分类结构，可将其划分为松散岩层、坚硬岩层以及采矿型主要含水层三大类别。松散岩层的孔隙含水层（pore aquifer）包含8个具有独特地层与岩石学特征的单元；坚硬岩层的空隙与喀斯特含水层（karst aquifer）共划分为16个单元。针对受采矿活动干扰的含水层区域，数据集进一步区分了正在作业的采矿区与已转运的废弃物堆放区域。
