FLUORESCENT METHOD FOR DETERMINING MINERAL COMPOSITION CLAY-LIKE FORMATIONS Russian patent published in 2016 - IPC G01N23/223 

FIELD: measurement technology.

SUBSTANCE: this invention consists in the fact that samples of minerals, X-ray fluorescence in them are excited in the optical wavelength range with subsequent determination of mineral, the prepared samples. the x-ray spectra are removed in the wavelength range of 200-400 nm and determining mineral halloysite at x-ray luminescence in the spectral range 290-400 nm with maximum radiation at λ=290-315 nm; determining mineral nontronite at maximum display in the band of 330-340 nm; determining mineral laumontite at wide band of the x-ray luminescence in the spectral range 280-400 nm with maximum radiation at λ=342 nm; determining mineral palygorskit at maximum display in the band with maximum λ=345 nm; determining mineral osorizavait by the presence of two wide low-intensity x-ray bands in spectral ranges 270-310 and 310-360 nm and maximum radiation at λ=289 nm and λ=340 nm; determining mineral alunite at very weak x-ray spectral range of 200-400 nm with maximum radiation in the band at λ=350 nm.

EFFECT: rapid and reliable diagnosis of mineral composition of clayline formations.
