STRUCTURAL DATA

Planar Structures:
Structure type | Strike | Dip | Separation
schistosity | 228 | 77 |

PETROLOGIC DATA

Rock Number: 1

Rock Type: basalt
Field Description:

-dense, greenish black volcanic containing anastomosing quartz carbonate veins
-quartz carbonate veins weather as pits leaving cm sized, euhedral, red garnets and thick biotite books
-basalt has small segregations of quartz feldspar that form in near vertical lineation
-they permeate the rock and are probably an alteration rather than amygdulte
-the basalt may have been plagioclase phyric
-SAMPLE B is platy black metallic from the carbonate biotite garnet pockets
-sample for x-ray, probable identification is ilmenite
