对于大批量化探生产性样品,抉择定量分析还是半定量分析,从地质效果或经济角度都是一个值得慎重考虑的问题。五十年代,生产性化探样品几乎全部采用半定量分析。七十年代中后期,化探样品的分析逐渐定量化。裸露矿,浅掩埋矿的逐渐减少和数学地质的引进,给人们以“化探分析必须定量化”的印象。而近几年来,除了有明确规定的项目,严格按规定
For large-scale geochemical exploration of productive samples, the choice of quantitative or semi-quantitative analysis, from the geological or economic perspective is a matter worth considering. In the fifties, nearly all of the productive geochemical exploration samples were semi-quantitatively analyzed. In the mid-1970s, the analysis of geochemical samples gradually quantified. Bare deposits, shallow burial mines and the gradual reduction of the introduction of mathematical geology, to give people the “chemical analysis must be quantified” impression. In recent years, in addition to clearly defined items, strictly in accordance with the provisions
