The abundance of chemical elements in olivines from pallasites and lunar and terrestrial rocks is investigated, and the character of this abundance is shown to be close to that in pallasites, and lunar and terrestrial rocks. In general, the structure of element associations in the olivines changes in the following sequence: skarns, basic and ultrabasic rocks, kimberlites, lunar rocks, and pallasites. It is found that one of the factors affecting the occurrence of the observed features is the effect of gravity on the formation of the rocks and minerals.
