ON ORIGIN OF ULTRAMAFIC ROCKS

Summary
During the last few years, petrologists and geophysicists have become particularly interested in the origin of ultramafic rocks. Papers by K.

The present author became more closely acquinted with this problem during his travels through Czechoslovakia (vicinities of České Budéjovice), USSR (Armenia) and German Democratic Republic (Erzgebirge), where he had the possibility of directly observing and studying numerous intrusions of ultramafic rocks and to discuss their origin with petrologists from these countries. Because most Polish geologists are not fully acquinted with these problems, this article might serve partly to fill an existing lack.
