STRUCTURAL DATA
Structure type | Strike | Dip | Separation |
---|---|---|---|
schistosity | 62 | 90 | |
cataclastic foliation | 181 | 72 |
-contact between multicomp gneiss and gabbro
PETROLOGIC DATA
Rock Number: 1
-dominantly augen GRDR containing mafic schlieren, mult. pegs, and ampb inclusions
Rock Number: 2
-W side of outcrop is contact containing granite
-contact is poorly exposed, so it is difficult to tell if intrusive contact or a fault contact
-contact zone covered contains rubble
-the GBBR is much finer and more mafic at this loc. which makes me suspect contact is intrusive and gabbro is much younger
-this may be one of the large, old Molson dikes
-sample A taken 75 cm from contact
