研究REE在生物圈中的分布及分配,对于探讨REE的地球化学性质和演化有其替殊意义,因此很早就有人开展这方面的研究了。1878年Cossa(据Robinson等,1958)报道了(木菊)材、烟草、葡萄等植物中含有少量稀土。后来Robinson等人又详细研究了北美胡桃树中的REE。近十几年来,有关REE生 Studying the distribution and distribution of REEs in the biosphere is of great significance to the exploration of the geochemical properties and evolution of REEs. Therefore, some researches have been conducted in this area. Cossa (Robinson et al., 1958) reported in 1878 that plants such as woodgrass, tobacco and grapes contain a small amount of rare earths. Later Robinson and others studied REE in North American walnut tree in detail. In the past ten years, about REE students
