-PHOTOS 1 and 2 general of old TNLT and augen GRDR intruded, 3 augen GRDR with inclusions of old TNLT and mafic TNLT, 4 and 5
general of spotted GRDR, 6 and 7 peg/aplt inclusions in spotted GRDR
PETROLOGIC DATA
Rock Number: 1
-even more complexities added to the system
-a new unit that is younger that the pegmatite/aplite granite-a beige spotted GRDR or GRNT
-fine grained buff to pinkish grey with 5 to 8% pink oval feldspar-QZ-BO-MG (cores) aggregates around 1 cm across
-this intrudes and includes all other units
-sequence AMPB increases-augen TNLT increases-- white TNLT LIT increases--old peg. increases--augen GRDR increases--peg. aplite increases--spotted GRDR
-there is also a charcoal grey mafic (14%) fine grained GRDR TNLT--it intrudes old TNLT and is included in augen GRDR (photo 3)
