Description:
Pedogenic carbonate carbon isotope data, occluded organic matter carbon isotope data, and bulk magnetic susceptibility data are from the Jiaxian section of the Chinese Loess Plateau. Samples were collected from the field in July, 2017. Between 1 and 16 discrete pedogenic carbonate nodules were collected from 121 different depths over a 58-meter section. Separate bulk loess samples were collected every 10 cm for magnetic susceptibility analyses. 697 individual nodules were drilled and their carbonate δ13C values were measured at the University of Texas Stable Isotope Laboratory. Between 1 and 16 nodules were analyzed for each respective depth. When enough material was available (668 nodules), splits of the samples were acidified and rinsed before being analyzed for the δ13C values of occluded organic matter at the University of Texas Stable Isotope Laboratory. 17 and 109 replicate analyses are also included for carbonate and occluded organic matter, respectively. Magnetic susceptibility measurements were conducted at Nanjing University. Magnetic susceptibility data were used to correlate to previously published age models for the Jiaxian section that were based on paleomagnetic reversals.
