FIELD: physics.
SUBSTANCE: minerals are sampled; X-ray fluorescence is excited therein in the optical wavelength range to recognise a mineral; the X-ray fluorescence spectra are recorded for the prepared samples in the wavelength range of 200-500 nm, and kaolin mineral is recognised by luminescence bands in the wavelength range of 290-400 nm with maximum emission at λ=335-357 nm; dickite is recognised by maximum emission at λ=350-370 nm; montromorillonite is recognised by luminescence bands in the wavelength range of 320-380 nm at maximum emission at λ=320-350 nm; pecoraite is recognised by luminescence bands in the wavelength range of 270-400 nm at maximum emission at λ=280-330 nm; nacrite is recognised by a wide X-ray fluorescence band at λ=270-500 nm at maximum emission at λ=340-350 nm.
EFFECT: higher expressivity and reliability of clay matter tests.
