DESCRIPTION:Speakers: Vladimir Kriventsov ()\nThe presented work shows the
  new results of a study of microparticles of the Sikhote-Alin meteorite us
 ing XANES and EXAFS methods. XANES / EXAFS spectra (Ni-K\, Fe-K\, W-L2)\, 
 using μ- and standard methods\, for meteorite microparticles and referenc
 e comparison samples were obtained both on experimental module X-ray Confo
 cal Microscopy situated on NRC “Kurchatov Institute” (Moscow) and at X
 RF-\, EXAFS- stations of Siberian Synchrotron Terahertz Radiation Center (
 SSTRC\, Novosibirsk). Some differences in the local structure and phase co
 mposition in different microparticles of the studied meteorite samples wer
 e determined. The interatomic distances and the corresponding coordination
  numbers were calculated. Various options for structural models are consid
 ered. Additionally\, the chemical and phase compositions\, and the morphol
 ogy of the samples were studied by SEM\, EDX\, and XRF methods. On the exa
 mple of a test meteorite\, the possibilities of the proposed approach for 
 the study of microparticles of complex composition are shown. The data obt
 ained by all the methods are in a good agreement.\nThe work was carried ou
 t in the framework of the RFBR projects no. 19-05-50046\, 18-03-01251. The
  work was done at the shared research center SSTRC on the basis of the Nov
 osibirsk FEL/VEPP-4-VEPP-2000 complex at BINP SB RAS\, using equipment sup
 ported by project RFMEFI62119X0022.\n\nhttps://indico.inp.nsk.su/event/24/
