Quantitative concentration differences of the elements Fe, Si, Mg, Ca, Al, Ti, Mn, K and P between the L and H group common chondrites are compared. The Fe difference (26%) is by far the largest. P is positively correlated with Fe, indicating that P may have some siderophile character despite the fact that it occurs either as apatite or merrilite in the common chondrites. P is distinctly enriched in the Fe-high enstatite chondrites.The degree of fractionation of most of the lithophile elements examined is 7-12%; fractionation of Ti appears to be a little less.A critical comparison of the SiMg relationship in the L and H groups of chondrites indicates that these two abundant lithophile elements are slightly fractionated between these two chondrite groups.
