PETROLOGIC DATA

Rock Number: 1

Rock Type: granodiorite
Descriptors:
megacrystic

Field Description:

-slightly finer grained matrix with phenocrysts representing 5 to 10 % of rock
-although they show normal 5 to .5 cm size range
-the old 050 direction is much stronger has resulted in shattering and some rotation in megacrysts
-there are also pink feldspathic stringers in this plane
-colour zonation of megacrysts is less obvious although they still show plag. overgrowth
