PETROLOGIC DATA

Rock Number: 1

Rock Type: granodiorite
Descriptors:
augened
biotite
Field Description:

-looks like the seriate GRDR
-in places it weathers grey-white and looks to be TNLT, but in general it is mottled pink and grey
-fabric variable from augen cataclasite to fol. GRDR

Rock Number: 2

Rock Type: gabbro
Descriptors:
schistose
hornblende-chlorite
Field Description:

-10% of exposure variable textures of gabbro from leucogabbro as next step to metagabbro (sample)
-inclusions (definitly) are highly deformed on margins but cores are just fol. (although severly in some metagabbro)
-metamorphic layering (GRNT lit) abundant in GRDR but generally don't penetrate gabbro
