STRUCTURAL DATA
Structure type | Strike | Dip | Separation |
---|---|---|---|
schistosity | 272 | 37 |
Rock Number | Type | Width (m) | Strike | Dip |
---|---|---|---|---|
0 | pegmatite | 0.00 | 82 | 51 |
-peg. intrudes amphibolite sequence that appears to be derived from mafic volc. and volcanogenic sediments
-Peg parallel fabric in amphibolite
-unit dips opposite way; it is planar and largely undeformed
PETROLOGIC DATA
Rock Number: 1
-25 cm dike of brick red to orange feldspar, KF>> PG, QZ, TL
-no MV visable
-no unusual minerals
-check Anderson for chemistry, looks fairly primative and may belong to Periterite Bay group
-if PB dikes follow the same eastward differentiation, then this would be the most developed of the barren peristerite zone dikes
-samples contain KF that could be separated for analysis if necessary
