Abstract

Many fine-grained igneous rocks, basaltic and felsitic in character, are difficult to classify. In numer­ous cases, it is impossible to classify these types of rocks by quick methods of identification. It was hoped at the beginning of this study that refractive indices of glasses formed by quick artificial fusion of samples from selected suites of igneous rocks would show a close cor­relation in chemical composition.
