由于稀土元素的地球化学行为在地质学中越来越引起人们的兴趣（参见Lipin和McKay 1989和Jones等人1996编辑的综述），大多数火成岩、变质岩和沉积岩中的主要稀土矿物正在被详细研究。稀土元素是许多矿物中的主要或微量成分（Burt 1989）。除碱性、过碱性和碳酸盐岩中特有的稀土矿物组合外，（Vlassov 1966; Burt 1989; Mariano 1989; Larsen 1996; Taylor and Pollard 1996; Wall and Mariano 1996; Khomyakov 1996），更常见的副矿物，如锆石，磷灰石，硬石膏，碳酸盐岩和萤石也是稀土载体，在岩石学过程中起着重要作用。稀土元素研究的主要应用是熔融矿物分配系数，用于模拟火成岩成岩过程。这将取决于后期分异阶段出现的主要矿物如磷灰石和锆石中稀土元素的相容性（McKay 1989）。众所周知，大多数稀土元素是发光激活剂（Pringsheim 1949; Levrenz 1950; Monod-Herzen 1966; Diecke 1968; Marfunin 1979;马歇尔1988; Waychunas 1988）。为了解释天然稀土矿物的阴极发光，必须将其阴极发光光谱与人工合成矿物的阴极发光光谱进行比较。
As the geochemical behavior of the rare earth elements (REE) is of increasing interest in geology (see the reviews edited by Lipin and McKay 1989 and Jones et al. 1996), the main REE minerals in most igneous, metamorphic and sedimentary rocks are now being studied in detail. REE are major or trace constituents in many minerals (Burt 1989). Besides the specific REE mineral assemblages which occur in alkaline, peralkaline and carbonatitic rocks (Vlassov 1966; Burt 1989; Mariano 1989; Larsen 1996; Taylor and Pollard 1996; Wall and Mariano 1996; Khomyakov 1996), more common accessory minerals such as zircon, apatite, anhydrite, carbonates and fluorites are also REE carriers and play an important role in petrologic processes. The major application of the REE studies is the melt mineral partition coefficient, used to model igneous petrogenetic processes. This will depend on the compatibility of the REE in major minerals occurring in late differentiated stages such as apatite and zircon (McKay 1989). Most of the REE are well known to be luminescence activators (Pringsheim 1949; Levrenz 1950; Monod-Herzen 1966; Diecke 1968; Marfunin 1979; Marshall 1988, Waychunas 1988). In order to interpret the cathodoluminescence (CL) emissions of natural REE bearing minerals, it is essential to compare their CL spectra to those of synthetic minerals.
