摘要
河北平原东部滨海平原第四系含水系统广泛赋存着地下碘水,碘含量一般200~800μg/L,最高可达1250μg/L。本文通过对地下碘水含水介质沉积环境及其地球化学特征、地下水中碘的水文地球化学特征等综合研究,认为本区地下碘水资源的形成与第四纪以来所发生的6次海侵密切相关。
On the coastal plain of Eastern Hebei the Quatermary aquifer system has wide occurrence of groundwater with abundant iodine.The iodinecontent is generaly 200~800μg/L in groundwater,the highest content of iodine reaching 1250μg/L.Deposition environment and geochemical charactristics of hydrous medium were studied by the authors.At the same time,hydrogeochemical charactristics of iodine in groundwater were studied too.On the basis of the above mentioned study,it may be inferred that the formation of groundwater with abundant iodine was directly related with the six time marine transgresions since the beginning of Quaternary.
