Polarity and proxy variations of the JY loess sequence. a Geomagnetic polarity timescale (GPTS)32,33. b Magnetic susceptibility (MS) and magnetostratigraphy of Luochuan (LC) profile27,31. c JY δ13CIC, mean, and magnetostratigrahy. The magnetostratigraphy is derived from inclination results measured by the alternating-field (AFD, light blue) and thermal (THD, purple) demagnetization methods. Dashed lines indicate the positions of paleomagnetic reversals (B/M Brunhes/Matuyama boundary, J Jaramillo, O Olduvai). Orange bars denote thick loess marker layers
