Rare earth elements (REEs) also known as lanthanides are a group of 15 metals with similar properties which are used for a broad spectrum of applications in industry agriculture and medicine.
As it can be seen from the Figure 1, it is impossible to explain the accumulation of neodymium, terbium, and holmium in hydrocarbon media manifested through the differentiated positive anomalies of the lanthanides in the REE composition merely by their trivalent state in geochemical processes.
