STRUCTURAL DATA
Structure type | Strike | Dip | Separation |
---|---|---|---|
schistosity | 271 | 37 |
-extreme flattening and cataclasis has reorientated all layering in the foliation plane
-PHOTO 1 contact between massive and pillowed flow
-PHOTO 2 typical of pillowed flow and epidosites
PETROLOGIC DATA
Rock Number: 1
-entire N part of this island is a sequence of pillowed 3 massive basaltic flows
-there appear to be minor laminated interflow sediments although extreme deformation make 6 observations uncertain
-all that remains of pillow structure are streaked out selvages and irregular epidosite cores
-there is minor quartz veining and is highly devormed and strung out in fol. plane
SAMPLE A -pillowed flow
SAMPLE B -massive flow
PHOTO 3 -Carol as scale--contact of basalts and GRDR-photo taken looking 300 degrees, approx. attitude of contact 240/44
