PETROLOGIC DATA
Rock Number: 1
-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
Rock Number: 2
-white weathering, foliated, quartz poor peg.
-BO and abundance of cm MV's and numerous TL
-traces of aquamarine apatite
-apatites are unusually blue for such a primative dike
-red GR is a common accessory, closely associated with BO and TL
-GR is rare around MV, where apatite is abundant
