crossbedded
feldspathic
Field Description:

-as previous station, thick beds a metre or more of light grey feldspar rich sand with thin interbeds averaging 15 cm...coarse feldspathic sand and MV knot sand
-bedding is highly disturbed, so crossbeds are recognized only as a series of disjointed fine grained lamination that met at odd angles

Field Description:

-white weathering, foliated, quartz poor peg.
-BO and abundance of cm MV's and numerous TL
