Textural and structural details in a boulder of metamorphic rock
This boulder is being used as decor at the margin of a parking lot in the Beltline area of Calgary. Within this gneissic, high-grade metamorphic rock, the light-coloured felsic veins (scale: the thickest ones are 1 to 2 cm wide) are deformed (folded and faulted; V-shaped folds right of centre, abrupt faulted termination of felsic vein at upper left).
