Journal ArticleDOI

Gary E. Stinchcomb,Gary E. Stinchcomb,Lee C. Nordt,Steven G. Driese,William E. Lukens,Forrest C. Williamson,Jack D. Tubbs +6 more
TL;DR: In this paper, a data-driven paleosol-paleoclimate model (PPM1.0) was developed using a combined partial least squares regression (PLSR) and a nonlinear spline on 685 mineral soil B horizons currently forming under MAP ranging from 130 to 6900 mm and MAT ranging from 0 to 27 °C.
Journal ArticleDOI
Reconstructing pH of Paleosols Using Geochemical Proxies
TL;DR: In this article, the authors proposed a method for pH measurement on soils, which requires friable material, thereby making it difficult to obtain pH measurements on soils with high friability.
Book ChapterDOI
Paleopedology as a Tool for Reconstructing Paleoenvironments and Paleoecology
TL;DR: This chapter emphasizes a robust multi-proxy approach to paleopedology that combines soil stratigraphy, morphology, mineralogy, biology, and chemistry to provide an in-depth understanding of paleoecology.
Journal ArticleDOI
The early miocene critical zone at karungu, western Kenya: An equatorial, open habitat with few primate remains
William E. Lukens,Thomas Lehmann,Daniel J. Peppe,David L. Fox,Steven G. Driese,Kieran P. McNulty +5 more
TL;DR: In this article, a deep-time Critical Zone (DTCZ) reconstruction focused on floodplain paleosols at the Ngira locality in Karungu, Western Kenya was performed.
Journal ArticleDOI
The effect of diagenesis on carbon isotope values of fossil wood
TL;DR: In this paper, the authors measured the carbon isotope (δ13C) value of modern and fossil wood and found that the apparent enrichment factor (ε) between the two species is 1.4 ± 0.4.
