The structure dig. 2, pi. 1) is somewhat porphyritic, the rounded cry- 

 stals of garnet, iVom 2 to 5 mm in diameter, appearing as phenocrysts. 

 The chloromelanite forms a medium-grained ground-mass where the grains 

 show an indistinct parallel arrangement.

This eclogite belongs to a Hne-grained and distincU}' foliated type. 

 The specimens kept in the collections of the Geological Museum in Chri- 

 stiania have been collected by H. Reusch in 1886. No further details about 

 its mode of occurrence are known but that it is an occurrence in the gneiss. 

 During my excursions I met with similar rocks at many places as inclusions 

 in gneiss. 



A bulk analysis of, this eclogite was executed by Mr. L. Thomassen 

 with the following result.

In the gabbro .facies such a composition would result in an olivine- 

 norite, poor in feldspar. In the amphibolite-facies the rock would crystallize
