• In this study an orbiculite from the Tanzawa massif has been investigated petrologically and spectrographically. First of all is given the megascopic and microscopic features of this rock: secondly its optical data; and thirdly are applied the plagioclase-twin method and trace element contents determined by spectrographical analysis as the key to the deduction of its origin, while, on the other hand, is estimated the chemical composition of this rock. All this has lead to the conclusion that the formation of this rock passed through a kind of magmatic process. And lastly, from such a genetical point of view are discussed the embryonal rock and the forming-mechanism of this orbiculite.
