Fig. 2. Depth plots of (a) low-frequency magnetic susceptibility, 
LF; (b) frequency-dependent magnetic susceptibility, FD; (c) anhysteretic remanent magnetization susceptibility, ARM; (d) hematite concentration; (e) goethite concentration; and (f) dithionite-extractable Fe/total Fe ratio (Fed/Fet). Gray bars and S notations denote the paleosols and L notations the loess units.
