PETROLOGIC DATA
Rock Number: 1
-highly variable dominantly old augen TNLT
-deformation extreme
-GRDR along contact of large Molson is leuco with equant feldspars in a quartz matrix
-this resembles WJC
Rock Number: 2
-Molson (major)
-probable width 20 to 25 m but only 20 to 22 m are exposed
-foliation is quite strong and also strong fracture set at 306 degree/87 degrees that has extensive alteration along it and it shows a consistent trend but highly variable dips.
-this dike is unusual in that it has included large xenoliths of CR, the largest 2 x 8 m and several small inclusions that show some thermal effect, predominantly bleaching and marginal assimilation
