biotite

Field Description:

-intensly deformed early granitic lite in EW direction
-tightly folded by 050 direction more/less same as previous stations with possible exception of more severe augening in the late direction

Rock Number: 2

layered

Field Description:

-370 cm, high mag. Molson dike
-lies in the 050 shear plane and shows a slight internal fabric in that direction
-centre of dike has a mm graine size with a small equant talc-serp. pseudomorphs that may have been OC
-this region is also most magnetiferous which consist with OC breakdown
-Samples A footwall chill
-Samples B to E taken at distances of 50,90, 140 and 220 cm above the footwall
