Notes: Orientation convention: strike taken on cut core face, measured in a clockwise direction 0°–360°, dip taken from cut core face downward, with direction referred to compass quadrant with north being at top of core. APC cores can be oriented by reference to Tensor tool measurement taken during coring.
