虽然被称为稀土，元素周期表上的元素镧（原子序数57）到镥（原子序数71），包括钇（原子序数37），在自然界中比许多工业上重要的有色金属更常见。稀土元素存在于氧化物、硅酸盐、磷酸盐和碳酸盐化合物中，或作为替代钙和锶的小组分存在，钙和锶的离子半径与稀土元素相似。稀土矿物更常见于伟晶岩、花岗岩和霞石正长岩中。稀土的进一步研究将有助于地球化学找矿，确定成矿过程，澄清地质过程，以及增加合金金属储量和产品区分。研究国际
Although called rare earths, elements lanthanum (atomic number 57) through lutetium (atomic number 71) on the periodic table, including yttrium (atomic number 37), are more common in nature than are many of the industrially important nonferrous metals. The rare-earth elements occur in oxide, silicate, phosphate, and carbonate compounds or as small fractions replacing calcium and strontium, whose ionic radii are similar to those of the rare-earth elements. Rare-earth minerals are more commonly found in pegmatites, granites, and nepheline syenites. Further study of the rare earths will aid geochemical prospecting, determination of mineralization processes, and clarification of geologic processes, as well as augmentation of alloy-metal reserves and product differentiation.
