Phosphorites (Area)

The Geological Survey Ireland (GSI), as partner and Work Package 7 (Minerals) leader of EMODnet Geology Phase III, are compiling information on phosphorite deposits. EMODnet partners are submitting the spatial extent of mapped deposits and established information; here you can view data collated thus far. Phosphorite deposits are found in sedimentary rocks, sufficiently rich in phosphate minerals. Phospherites are authigenic mineral deposits, formed in situ on the sea floor; they generally occur in deeper waters than placer deposits and are primarily used in the phosphate fertiliser industry.爱尔兰地质调查局（Geological Survey Ireland，GSI）作为欧洲海洋地质观测网第三阶段（EMODnet Geology Phase III）的合作伙伴及第7工作包（矿物）负责人，正在汇编磷矿床相关资料。EMODnet各合作伙伴已提交已填绘矿床的空间分布范围及已确认的相关资料，您可在此查看迄今已汇总的全部数据。磷矿床赋存于沉积岩中，且磷酸盐矿物含量足够富集。磷块岩（phosphorite）属于自生矿物矿床，形成于海床原位；其赋存水深通常较砂矿床（placer deposits）更深，且主要应用于磷酸盐肥料生产行业。
