兰开夏郡克林普顿布鲁克鲍兰德页岩地层的露头处涌出硫磺泉水。春天的标志是白色和黄色黄钾铁矾的沉淀。类似的轻硫同位素组成表明黄钾铁矾源自黄铁矿页岩的表面氧化。页岩中含有异常浓度的硒和其他微量元素，与英格兰北部鲍兰页岩地层的其他暴露情况相同。硒存在于黄铁矿中，在氧化过程中释放出来，并融入到克林普顿布鲁克的黄钾铁矾中。现场的小规模水流和偏远情况不会造成环境问题，但数据说明了黄铁矿在更大范围内风化进入地下水的潜在危险。补充材料：用于 Crimpton Brook Bowland 页岩样品分析的原始 LECO（TOC% 和 S%）数据可在 https://doi 上获取。 org/10.6084/m9。无花果共享。 c. 6379094
A sulfurous spring emerges at an outcrop of Bowland Shale Formation on Crimpton Brook, Lancashire. The spring is marked by the precipitation of white and yellow jarosite. Comparable light sulfur isotope compositions suggest that the jarosite was derived from surface oxidation of pyritic shale. The shale contains anomalous concentrations of selenium and other trace elements, in common with other exposures of the Bowland Shale Formation in the north of England. The selenium is resident in the pyrite, and was released during oxidation and incorporated into the jarosite in Crimpton Brook. The small scale of the water flow at the site and the remote situation pose no environmental problem, but the data exemplify the potential danger of pyrite weathering into groundwater on a larger scale.Supplementary material: Raw LECO (TOC% and S%) data for the Crimpton Brook Bowland Shale sample analyses are available at https://doi. org/10.6084/m9. figshare. c. 6379094
