Parent material and soil texture both play negligible roles in this regression. When combined with similar published studies (n = 1481), r2 improves slightly (r2 = 0.31; p < 0.001). Caution is therefore advised in using this or any previously published regression for inferring paleoprecipitation from paleosols. However, in the combined data set, carbonate horizon–bearing soils correlate with a mean annual precipitation of < 760 mm (p < 0.05). Thus the presence vs. absence of pedogenic calcium carbonate is a good indicator of paleoprecipitation above or below this value. This content is PDF only. Please click on the PDF icon to access.
