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. … WebTherefore, REE concentra- tions in a sample are often normalised to chondritic meteorites which represent the primordial earth. These chondrite- normalised plots should normally result in...
WebFor normalizing REE data of fine siliciclastic rocks both PAAS as well as Chondrite values are used. Ideally both would given similar normalized REE pattern. WebWhen you plot a REE Chondrite normalized plot, you plot all the rare earth elements (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm Yb, Lu). However, as the half life for Pm is very short, you cannot have …
