在地质物料中,金、铟、碲和铊的含量非常低,它们在地壳中的丰度估计为:金0.001—0.0035ppm、铟0.11—0.14ppm、碲0.001ppm铊0.3—1.3ppm。在地球化学勘探过程中,无论是检测岩石或风化产物中的成矿元素,还是用作各类矿床找矿时的指示元素;或者在研究元素的共生情况时,用同一份样品溶液测定全部四个元素丰度的方法,从经济效益和分析速度方面考虑,都是特别有利的。
The content of gold, indium, tellurium and thallium in geological materials is very low, and their abundance in the crust is estimated as gold 0.001-0.0035ppm, indium 0.11-0.14ppm, tellurium 0.001ppm thallium 0.3-1.3ppm. In geochemical exploration, whether it is to detect ore-forming elements in rocks or weathering products, or to be used as indicator elements in prospecting for various types of deposits, or in the case of symbiosis of elements, the same sample solution is used to determine all four A method of element abundance, from the economic efficiency and analysis speed considerations, are particularly beneficial.
