X-ray intensity ratios of Si/Al, Si/Fe, and Al/Fe in micron-sized particles of geochemical standards were found to vary linearly with the composition ratio. The same linear relationship was found for samples of the clay minerals kaolinite and illite.

Резюме

Резюме

Было обнаружено, что отношения интенсивностей рентгеновских лучей для Si/Al, Si/Fe и Al/Fe в частицах микронного размера геохимических эталонов изменяются линейно с изменением отношения составов. Такое же линейное соотношение было обнаружено для образцов глинистых минералов каолинита и иллита.

Kurzreferat

Kurzreferat

Es wurde herausgefunden, daß das Verhältnis der Röntgeninten-sitäten von Si/Al, Si/Fe und Al/Fe in mikrongroßen Partikeln geochemischer Standarts linearisch mit dem Aufbauverhältnis variiert. Dieselbe linearische Verwandtschaft wurde in Proben der Tonmineralien Kaolinit und Illit gefunden.
