化探工作中土壤测量和水系沉积物测量一样,必须进行方法性试验,对于土地辽阔、自然地三条件差异较大,地质背景又不同的我国各地,进行此了工作不仅有功亍丰富基础地质科学,还有其现实的经济意义。 Geochemical surveys, like soils and sediments in water systems, must be tested in a methodological manner. For all parts of our country where the land is vast and the natural conditions are quite different and the geological backgrounds are different, this work has not only done well in enrichment of basic geosciences , As well as its realistic economic significance.
