抄録/ポイント： 北太平洋西部,南鳥島周辺の排他的経済水域における希土類元素とイットリウム(併せてREYと称する)を発見した。総REY濃度の最大値は約7000ppmに達し,これは陸上の従来型REY鉱床や海洋におけるその他の既知の潜在的REY資源について報告されている値よりずっと高い。異常にREYに富む泥は豊富なフィリップス沸石と生物源燐酸カルシウムを特徴とする。更に,REY濃度が最高の地層が海底の~3m下方に存在する。特に,重希土類元素に富む高REY含量のこれらの地層が地下浅所に埋没していることは,この新たに見つかった異常にREYに富む泥が有望なREY資源であるかもしれないことを示唆している。(翻訳著者抄録)
