Figure F3. Representative orthogonal vector plots of AF demagnetization steps, Sites U1322 and U1324. A. Type 1 curve, Hole U1322B (25.26 mbsf). B. Type 2 curve, Hole U1322B (96.36 mbsf). C. Type 1 curve, Hole U1324B (11.56 mbsf). D. Type 2 curve, Hole U1324B (12.06 mbsf). Type 1 curves show directional deviation during the first few low-field steps, which usually disappears after the 30 mT step, followed by characteristic remanent magnetization (ChRM) directions pointing toward the coordinate center. Type 2 curves show the same starting trend but additionally develop a strong horizontal deviation at higher demagnetization steps. Gray line = gyroremanent magnetization (GRM)-corrected demagnetization curve measured following method described by Dankers and Zijderveld (1981), for further details see the text. DIRM = drilling-induced remanent magnetization.
