Figure F33. Thermal demagnetization of discrete Sample 335(312)-1256D-231R-1W, 115 cm, from Gabbro 2, showing a clear two-component remanence structure (excluding the initial drilling-induced component). A negative inclination component that unblocks between 200° and 500°C and a positive inclination component that unblocks between 500° and 580°C are antipodal, indicating remanence acquisition during different geomagnetic polarity periods. Solid circles = projection onto the horizontal plane, open circles = projection onto either the vertical north–south or east-west planes.
