PETROLOGIC DATA

Rock Number: 1

Rock Type: sandstone
Descriptors:
bedded
feldspathic
Field Description:

-as last station
-decrease in abundance of Al rich MV knot beds and reduction in average bed thickness to 15 cm to 20 cm
-GR disseminated, especially in MV rich beds-TL restricted to vicinity of pegs that follow the foliation
-main units are now massive or possibly graded sands with coarse sands to quartz granule sand horizons 1-2 cm thick
-cross bedding rare
-tops uncertain
-pegs extensivly baudinaged - flattening and extrusion severe
-SAMPLE A massive sand
-SAMPLE B CLCC layer 25 cm thick
-CLCC layers are more abundant and thicker with QZ-EP cores and EP-ampb-BO veins
-they occur as horizons and are baudinaged
