矿物中的气液包裹体虽然大量存在,但单个包裹体的重量和体积甚微.在气液包裹体成分分析中,目前国内多数单位均采用原子吸收的常规方法来进行.因此,需要挑选纯度为98%以上的单矿物几十克,才能达到对样品重量的最低要求.要挑选几十克单矿物,用一般采样方法是困难的,对某些矿物几乎是不可能的,特别在选矿设备不太完善的单位更是如此.这就大大限制了包裹体成分分析方法的推广和应用.解决这个问题有两个途径,即:①
Although a large number of gas-liquid inclusions exist in minerals, the weight and volume of individual inclusions are very small. In the composition analysis of gas-liquid inclusions, most of the units in China currently use the conventional method of atomic absorption, therefore, the purity For a single mineral of 98% or more dozens of grams, in order to achieve the minimum weight of the sample.Selecting dozens of grams of a single mineral, the general sampling method is difficult, almost impossible for some minerals, especially in the mineral processing equipment This is especially true for less well-established units, which greatly limits the promotion and application of the method of composition analysis of inclusions.There are two ways to solve this problem: ①
