Figure F11. Subophitic dolerite (Sample 345-U1415N-4R-1, 52–54 cm [Piece 12]; under crossed polars). A. Dolerite contains a xenolith/enclave of an anorthositic troctolite (2 mm mean grain size) to the right of the red dashed line. Red boxes (tick marks show upward direction) indicate locations of images in B and C. Red line indicates the orientation of the weak plagioclase foliation. B. Bent plagioclase crystal with deformation twins in the dolerite portion. C. Plagioclase crystals within the anorthositic troctolite xenolith showing subgrains (red arrow) and deformation twins.
