英文摘要	Selective chemical extraction method was utilized to fractionally extract rare earth elements (REEs) in cobalt. rich crusts and bedrock samples from the Pacific survey area, and REEs concentrations were determined by inductively coupled plasma mass spectrometry (ICP-MS). A method was established for the chemical phases analysis of REEs in cobalt. rich crusts. The results showed that the REEs enrichment in different phases in cobalt. rich crusts conformed to the following order: iron oxide phase>manganese oxide phase>residual phase>carbonate phase>adsorbed phase. About 70.2%-73.9% of total REEs contents were mainly enriched in the iron oxide phase and the recoveries were 94.8%-105.9%. Therefore, most of REEs were controlled by amorphous FeOOH minerals. In different geological bodies, occurrence phase of REEs had significant difference. REEs were mainly enriched in the carbonate phase in carbonate rock, the residual phase in basalt and phosphate rock, and the iron oxide phase in cobalt. rich crusts and polymetallic nodules. In different structural layer of cobalt. rich crusts, REEs in the new layer were mainly enriched in the iron oxide phase, and REEs in the old layer were mainly enriched in the residual phase. It suggested that phospharization played a more significant role on the REEs enrichment in the old layer.
