How to normalize the REEs to the the shale references (PAAS or NASC)? Is it as simple as dividing the REE value by the reference one?
Hi Ahmad, yes you gave the answer already. It is similar to normalising the REEs to chondritic compositions.
Dear Ahmad,
Yes that is right. By dividing your obtained data into the PAAS or NASC values, you can gain the normalized data.
Kind regards,
Rahim
Many thanks for your kind contribution

What if one gets Ce anomaly around 1.0? Does this mean any significant finding from your point of view except having constant ratio and stable deposits over time?
please take into considerations that the Ce anamoly was simply calculated from:
Ce anamoly= 2*Ce normalized/( La normalized+Pr normalized)

Exactly, Just divide the obtained values of REE by the reference values
What if the mean Ce anomaly was around -0.106±0.009 (according to Wright el al., 1987) and the ∑LREE represented about 0.8-0.9% of ∑REEs?
Do they mean Ce depletion and LREE enrichment? If yes, how to match between the Ce depletion and LREE enrichment whereas Ce plays a significant role in the LREE score.
