samples belong to the light rare earth element (LREE)-rich type and are enriched in LREEs relative to heavy rare earth elements (HREEs). The distribution curves of REEs in mudstone are highly similar.... They are all enriched in light rare earth elements relative to heavy rare earth elements, and HREE depletion is the clearest in mudstone. However, such similarity just provides possible relationship between......
