cataclastic foliation | 291 | 69 |
-appears to be parallel to shearing as there is resemblence continuity of layering across outcrop
-flattening extreme, tiny reef 5 m exposed 30 m under water
PETROLOGIC DATA
Rock Number: 1
-section of mafic BO+/-HB matrix pebble conglomerate and budded mafic to leucocratic BO wackes
-pebbles include granitic, quartz and highly flattened mafic (probably volcanic)
-minor interbedds of calcsilicate bearing sands--10 to 25 cm thick
-foliation invaded by pink and white mottled pegs that are sheared to near mylonite texture
-there are thin amphibolitic horizons (SAMPLE B) that average 15 cm and are continuous across outcrop
-conglomerate matrix appears to be a dirty feldspathic sand-deformation too high to recognize lithic fragments
