摘要：

Ordinary chondrites from H, L and LL groups were studied using Mossbauer spectroscopy with a high velocity resolution. Mossbauer parameters of spectral components were obtained using new fitting model excluding the effect of previous misfits of troilite component. Obtained parameters were related to corresponding iron bearing minerals in ordinary chondrites. The differences of these minerals content as well as small differences in the hyperfine parameters of the same iron-bearing minerals were revealed for different meteorites. The temperatures of equilibrium cations distribution in silicates were estimated and suitable parameters for classification of H, I. and LL chondrites were supposed using Mossbauer parameters.
