PLATE XVIL. 
Fia. 1. Granophyric structure in soda-granite from near Hardingville. The 
feldspar is represented by parallel horizontal lines; the quartz is 
unshaded; the hornblende is represented by diagonally crossing 
lines, zircon by irregular heavy cracks, and chlorite by arrow 
points. In the upper left hand quadrant the quartz is mostly in 
minute trigonal prisms variously shown by different sections. In 
the upper right hand quadrant the quartz is regular and minute 
at the centre, but becomes coarse and irregular outside. In the 
lower half the quartz is seen radiating out from a crystal of feld- 
spar, becoming coarser and more irregular as it continues its 
growth. The feldspar between these quartz growths is in part 
optically continuous with the central crystal. From Spec. 656.
