Loess accumulation and soil formation in central kansas, United States, during the past 400 000 years
Abstract Based on interpolation of thermoluminescence dates and the mean accumulation rate of 0.034 mm yr −1 , four cycles of pedogenic CaCO 3 accumulation are found within the Loveland Loess: 415–325 ka, 325–250 ka, 250–195 ka and 195–95 ka. The four CaCO 3 peaks correspond chronologically to marin...
