Uranium in stream sediment

THIS DATASET HAS BEEN WITHDRAWN **This dataset was created for the "Britain beneath our feet" atlas using information extracted from the Geochemical Baseline Survey Of The Environment (G-BASE) For The UK . For Uranium in stream sediment data please see Geochemical Baseline Survey Of The Environment (G-BASE) For The UK ** Geochemical Baseline Survey Of The Environment (G-BASE) coverage for Uranium in stream sediment. The G-BASE programme involves systematic sampling and the determination of chemical elements in samples of stream sediment, stream water and, locally, soil, to build up a picture of the surface chemistry of the UK. The average sample density for stream sediments and water is about one site per 1.5-2km square. Analytical precision is high with strict quality control to ensure countrywide consistency. Results have been standardised to ensure seamless joins between geochemical sampling campaigns. The data provide baseline information on the natural abundances of elements, against which anomalous values due to such factors as mineralisation and industrial contamination may be compared.

本数据集已被撤回。该数据集系为《英国地表之下》地图集而创建，其信息源自英国环境地化基准调查（G-BASE）。有关溪流沉积物中铀含量的数据，请参阅英国环境地化基准调查（G-BASE）。环境地化基准调查（G-BASE）针对溪流沉积物中铀的覆盖范围。G-BASE项目包括系统的采样和测定溪流沉积物、溪流水以及局部土壤样本中的化学元素，以构建英国地表化学的图像。溪流沉积物和水的平均样本密度约为每1.5-2平方公里一个采样点。分析精度高，质量控制严格，以确保全国范围内的数据一致性。结果已标准化，以确保地化采样活动之间的无缝对接。这些数据提供了元素自然丰度的基准信息，异常值（如成矿和工业污染等因素引起的）可以与此进行比较。
