The remainder of the core is criss-crossed by white veins of chrysolite. All measured microstructures are related to the section plane which has been chosen perpendicular to S1 dip. Interval 107-651A-58R-4, 98 to 102 cm, brackets a fault plane parallel to the section plane. Dip is 50 degrees, slickensides pitch is 60 degrees. Interval 107-651A-58R-4, 0-15 cm brackets a fault plane dipping 65 degrees, slickensides pitch is 70 degrees.
