PETROLOGIC DATA

Rock Number: 1

Rock Type: siltstone
Descriptors:
layered
garnet-muscovite bearing

Field Description:

-light grey quartz rich siltstone with numerous poikiloblastic pink garnets upto 3 cm x 1 cm and red subhedral GR upto 8 mm
-large GR surrounded by coarse MV flakes
-there are also small knots of MV
-several thin horizons are a hematite stained quartz rich sands
-there are a few granitic patches that resemble mob?? but must be boudinaged veins as the grade looks to low for partial melt
