PETROLOGIC DATA
Rock Number: 1
-Highly tectonized, re-crystallized, volcanic derived ampb
-the units are completely transposed and tectonized but appear to be volcanic and not Sed.
-GR is sparatic
-there is extensive alteration of HB to BO, EP
-there are a few quartz veins, one sampled appears to have coarse grains of IM (sample B)
-there is local intense HB-BO alteration that appears to be tectonically controlled and is most evident in baudinage
Mineral | Abundance (%) |

Rock Number: 2
-One baudinage layer around 1 x 2 m of dark green actinolite-mafic rock
-there is no layering in it
-it appears to correspond to the foliation plane but this is unlikely to be a primary volcanic bedding plane
-this probably represents a mafic dike or sill
