Figure F78. Serpentinite clasts recovered from Hole 1200A. Note the planar margins of most clasts (arrows), where they have broken along joint-controlled serpentine veins, remnants of which are preserved along clast rims. Note also the common bleached selvages along most clasts, indicating reaction with the host serpentine mud.
