JOURNAL FREE ACCESSA simple relation between the amounts of constituents of igneous rocks is found. This is that the sum of amounts of oxygen, calcium, potassium, and titanium is a constant a little above 53%, while that of the other elements are about 47%. The ratio of these figures may just be given by mass numbers of oxygen and nitrogen. Thus the constituents of igneous rocks can be classified in two series of elements Which are called O and N series by the author. This relation seems to have some close correspondency with Prof. Eddington's assumption of extremely ionized state of materials on hot stars.
The author wishes to express his thanks to Prof. H. Nagaoka for his kind discussions and valuable suggestions, and Dr. A. L. Day for his kind gift of the Report of the Carnegie Institution of Washington which gave the author a valuable hint leading him to the present conclusion.View full abstractDownload PDF (553K) -
