and orthoclase, and having a granitoid struc- 
ture. With these minerals are very commonly associat- 
ed others in lesser quantity, such as plagioclase, augite, 
hornblende, biotite, magnetite, apatite, zircon, sodalite, 
and sphene. The most important and classic occurrence 
of elffiolite-syenite is in southern Norway, where it is the 
repository of many interesting minerals and of several of 
the very rare metals, such as yttrium, cerium, niobium, etc. 
Varieties of this rock containing considerable zircon have 
been frequently designated as zircon-syenite; a variety 
from Miask, Russia, with much mica, is known as miascite ; 
one from Mount Foya in Portugal, which was supposed 
to contain hornblende, as foyaite; and one from Ditro 
in Transylvania, containing sodalite and spinel, as ditroite.
