Rather exhaustive treatises exist on the hornfels-facies in the contact- 

 metamorphic rocks of the Christiania region by V. M. Goldschmidt and on 

 the amphibolite facies in the metamorphic rocks in the Orijärvi region by 

 the present writer. The sanidinite facies represents the same equilibrium 

 conditions as those prevailing in the experimental research under atmos- 

 pheric pressure. 



The present paper endeavours to deal with the eclogite facies, as re- 

 presented in the eclogites of Norwav.
