No, argon is not part of the group known as rare earth elements. Rare earth elements are a series of 15 elements known as the lanthanides, (atomic numbers 57 through 71 - lanthanum through lutetium) and include yttrium (atomic number 39) and scandium (atomic number 21). They fall under the category of metals. Argon is a gas.
To measure the abundances of rare earth elements in clinopyroxene and olivine of iron-silicon in a fulgurite, were made to determine the oxygen fugacity required.
