Sodium and Fe occupy up to 1% and 4%, respectively, of the M site. The major coupled substitution is REE 3+ + Si4+ ??? Ca2+ + P5+. The substitution REE 3+ + Na+ ??? 2Ca2+ has been of minor importance.

WebApr 13, 2024 · The enrichment of light rare earth elements (LREE) relative to heavy rare earth elements (HREE) is shown by the ratios of chondrite normalized (La/Sm)n, (La/Yb)n, and (Tb/Yb)n. Chondrite-normalized REE show strong LREE fractionation with (La/Yb)n = 18.10 on average.
WebIf you want to normalize your data, you can do so as you suggest and simply calculate the following: z i = x i − min ( x) max ( x) − min ( x) where x = ( x 1,..., x n) and z i is now your i t h normalized data.
