STRUCTURAL DATA
-this station must be sampled for pegmatite
-hornblende feldspar quartz pegmatite abundant in core and easily sampled--tame for zircon to go to T. Kragh
PETROLOGIC DATA
Rock Number: 1
-major Molson dike
-100 to 110 m at 175/65
-core exposed--coarse gabbro norite to websterite
-good accumulations of orthopyroxene
-pitted weathering may be olivine pseudomorphs weathering out
-very little cumulus texture
-may be apical portion near roof closure because of homo-equi texture, lack of cumulates and abundance of gabbro pegmatites in the core of the dike
-margins not exposed - east ride within 2 m of granite-finer grained may have olivine (foot wall)
