Abstract

In view of the widespread interest that the subject of the differentiation of rock-magmas is exciting among geologists generally I am led at this time to call your attention to one of the most recent, and at the same time one of the most important contributions which has yet been made. My notice will be brief, and will consist chiefly of an exhibition of specimens of many of the most notable rock types. An explanation of some of the most significant features will be given. Photographs of some of the most characteristic rock-masses as they appear in the field will be shown. These were obtained during a recent trip through the Caucasus region in company with the Russian investigator himself, guiding one of the excursions of the Seventh International Geological Congress.
