WebOn the primitive normalized trace elemental diagram, they display enriched signatures for LILE and depletion for HFSE. Similarly, the chondrite normalized REE patterns indicate the LREE... WebThus historically, “chondrite-normalized REE plots” have been based on volatile-free chondrites (Fig. 1). Columns 5, 7, 11, and 13 represent CI (carbonaceous) chondrites, which contain carbon, water, and other volatile elements, thus the values are … For reference, I have included plots of chondrite-normalized REE … Visit the main Washington University in St. Louis website 1 Brookings Drive / St. …

WebMar 1, 2024 · Chondrite-normalized REE patterns are rather flat between La and Sm and then decrease towards Yb. 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 10, 2024 · Plots of primitive mantle and chondrite normalized trace element and rare earth elements (REE) patterns are illustrated in Fig. 5. The gabbroic and dioritic rock samples are characterized by the lowest trace element abundances of incompatible elements; whereas, granitic samples show higher trace element abundances but low Ti, … rowe building supply spruce pine
