海底矿产作为REY(稀土元素和钇)的重要来源,吸引大量研究人员的兴趣。针对稀土元素在深海软泥和结核结壳的分布和性质进行的众多调查结果显示稀土资源异常丰富。然而,目前针对其成因仍有很多争议。Bernat(1975)发现锰结核样品显示为Ce正异常且稀土丰度是鱼残骸的1/10。钙十字沸石的稀土含量比鱼残骸低两到三个数量级。Toyoda和Tokonami(1990)对鱼残骸和磷灰石颗粒的赋存状态 Seabed minerals, an important source of REY (rare earths and yttrium), have attracted the interest of a large number of researchers. A large number of surveys of the distribution and properties of rare earth elements in deep sea slime and nodules show that the rare earth resources are exceptionally rich. However, there are still many controversies about its causes. Bernat (1975) found that manganese nodules showed a positive Ce anomaly and a rare earth abundance that was 1/10 of the fish wreckage. The rare earth content of phillipsite zeolite is two to three orders of magnitude lower than the fish wreckage. Toyoda and Tokonami (1990) on the occurrence of fish debris and apatite particles
