Content

Rare-earth elements contain valuable information on rock forming geological processes that is used in geochemical research. The hard X-rays of synchrotron radiation of the VEPP-4M storage ring for determine concentrations of rare-earth elements in geological samples was used. The excitation energy for the determination of rare-earth elements (La-Lu) was 57-85 keV. The Compton and the multiple scattering of radiation from geological samples also was analysed. The article presents the main parameters of the minimum detection limits of rare-earth elements in geological samples by the XRFA-SR method.

The work was done using the infrastructure of the Shared-Use Center "Siberian Synchrotron and Terahertz Radiation Center (SSTRC)" based on VEPP-4M of BINP SB RAS (Novosibirsk, Russian Federation). This work was funded by the RFBR and Government of the Novosibirsk Region within the framework of the research project 17-45-540618.
