PETROLOGIC DATA

Rock Number: 1

Rock Type: sandstone
Descriptors:
massive
muscovite and garnet bearing
Field Description:

-massive units with no bedding features visable other than highly folded festooned style cross beds
-the unit appears equivelent to the massive festooned sands of Beryl Island section with one exception
-this unit has many epidote rich calcsilicate horizons
-deformation is very complex and largely disharmonic
-it appears to be distorted cross fold pattern
-probably imposed by the superposition of compressive deformation on the 050 zone onto a pre-existing minor fold pattern
-axis are consistant but axial surfaces are fanned through 80 degrees
-I have no idea what primary bedding direction is
-less than 1% of outcrop is TL rick
-prygmatically folded PGMT veinlets
