| Abstract: | In this paper, the chemical compositions of 105 rock-forming minerals of the volcanic rocks in Tengchong have been determined by the microprobe and systematically studied. This indicates that in the lavas chrysolites predominate, together with a few hyalosiderites; for the orthopyroxenes, bronzites predominate, together with a few hypersthenes; for the clinopyroxenes, augites predominate, together with a few enstatite diopsides; labraclorites and part andesines predominate, together with a few oligoclases; the hornblendes are the ferrian pargasitic ones and the biotites both titano-ferrobiotites and ferrobiotites |
