一般的造岩硅酸盐矿物通常含有低含量的REE(大部分低于10ppm),因为相对较大的REE离子与这些矿物的晶体结构是不相容的。火成岩的总REE含量通常在几百ppm的范围内,而副矿物相是这些元素的赋存体。这些副矿物对火成岩和变质岩成岩过程中REE的行为
Typical rock-forming silicate minerals usually contain low levels of REE (mostly below 10 ppm) because relatively large REE ions are incompatible with the crystal structure of these minerals. The total REE content of igneous rocks is usually in the range of a few hundred ppm, while the accessory mineral phase is the deposit of these elements. The behavior of these secondary minerals on REE during igneous and metamorphic diagenesis
