摘要：

Study of four Chelyabinsk LL5 ordinary chondrite fragments with different lithology was carried out using X-ray diffraction and Mössbauer spectroscopy with a high velocity resolution. The Fe2+ occupancies of the M1 and M2 sites in olivine, orthopyroxene, and clinopyroxene determined using X-ray diffraction and Mössbauer spectroscopy were compared. Distribution coefficients KD and the temperatures of cations equilibrium distribution Teq in the olivine and orthopyroxene were evaluated. © 2017, Allerton Press, Inc.
