在地质找矿工作中,对稀有矿物及其伴生元素进行查定,通常配合化学分析、光谱分析或其它测试手段,但是很多含有稀有分散元素的矿物,粒度小而又以不同形态赋存于其它矿物中,镜下鉴定困难。在进行化学分析或光谱分析时,取样量不能满足测试要求。六十年代激光技术问世以来,很快地作为一种新的光源应用于发射光谱分析,对微细(微区)试样的物质成分的研究,发挥了较好的作用。关于激光光谱定量分析,国内已有报道,给澈光光谱定量分析指出了切实可行的方向。
In the geological prospecting work, the rare minerals and their associated elements were investigated, usually with chemical analysis, spectral analysis or other testing methods, but many minerals containing rare dispersing elements with small particle size and in different forms occur in other In minerals, microscopic identification is difficult. In chemical analysis or spectral analysis, the sample size can not meet the test requirements. Since the advent of laser technology in the 1960s, it has been rapidly used as a new light source in emission spectroscopy and has been instrumental in the study of the material composition of fine (microdomain) specimens. On the laser spectroscopy quantitative analysis, has been reported in China, to Che light spectroscopy quantitative analysis pointed out the practical direction.
