Comparison of the chemical compositions of meteoric and meteoritic matter
Abstract
Millman's (1972) data concerning the relative content of Na, Mg, Ca, and Fe in the Draconids are compared with the corresponding data for carbonaceous chondrites of the CI, CII, and CIII types and for ordinary chondrites of the H, L, and LL types. It is found that the relationship between the Fe/Mg, Na/Mg, and Ca/Mg ratios in the Draconids is consistent with their progressive changes in carbonaceous chondrites in the transition from type CIII to type CI.
