Mineral compositions of the ordinary chondrites Dhajala H3.8, Andreevka L3.4, Manych, and Chainpur LL3.4, as well as of the carbonaceous chondrite Kainsaz CO3 were investigated using Moessbauer spectroscopy and XRD analysis. Results indicate that the mineralogy of chondrules in these chondrites is different from that of the matrix. It was found that chondrules of ordinary chondrites contain more pyroxene and less olivine, compared to the matrix. Olivine of the matrix is more ferruginous and compositionally bimodal. The Fe(olivine)/Fe(pyroxene) ratio in the matrix and chondrules of chemically unbalanced chondrites is higher than in chondrules with balanced compositions, indicating the history of more rapid heating and subsequent cooling in the unbalanced chondrite matter.
