The first results of the investigation of microparticles of the Sikhote-Alin iron meteorite are shown. Measurements was carrying out on experimental module X-ray Confocal Microscopy [1] situated on NRC “Kurchatov Institute”. The experimental parameters are excitation energy 20 keV, the size of the excitation radiation spot on the sample is 15 μm, the scanning step is 20 μm, the measurement time at the point is 10 sec. Two-dimensional maps of the distribution of rock-forming (Ti, Mn, Fe, Ni) and microelements (V, Cr, Cu, Zn, Ga, Ge, As, Rb, Sr, Y, Zr, Mo) in the samples were obtained. This work was partially supported by Comprehensive program of fundamental scientific research of the SB RAS project №0330-2018-0031.
