According to the constructive principles of these diagrams, the following aspects must be thought carefully : the rock types to be studied must be the same or nearly the same as those that can be discriminated by the diagram ; to avoid mixed or incorrect signals that could be produced, two or more such diagrams shall have to be jointly used ; for special rock types, such as a - type granites or potassic igneous rocks, special discriminative diagrams have to be determined and selected respectively ; the samples to be studied can not be altered ; in general, the diagrams must be used carefully with archean samples ; the petrotectonic assemblage or an expert system are recommended to be used together with the discrimination diagrams
強調指出：所採集的樣品必須新鮮（無蝕變或極弱蝕變） 、非堆晶的巖石；選擇的判別圖解必須與判別的巖石類型相一致，即對花崗巖類要用花崗巖的判別圖解，不能用玄武巖的判別圖解；對特殊類型巖石要選擇專門用於該類型巖石的判別圖解，如堿性花崗巖，鉀質火成巖；要應用多種圖解綜合判斷；不能用單個樣品，而應作多個樣品分析；要注意所選擇判別圖解的特別說明等。
