A data-driven spline model designed to predict paleoclimate using paleosol geochemistry

2016 · American Journal of Science

Paleosols (fossil soils) are abundant in the sedimentary record and reflect, at least in part, regional paleoclimate. Paleopedology thus offers a great potential for elucidating high resolution, deep-time paleoclimate records. However, many fossil soils did …

Reconstructing pH of Paleosols Using Geochemical Proxies

2018 · The Journal of Geology

Soil pH is essential for understanding weathering, nutrient availability, and biological-edaphic relationships. However, standard pH measurement on soils requires friable material, thereby excluding most paleosols. In this article, bulk geochemical proxies for pH are developed …
