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
