IDENTIFICATION AND CLASSIFICATION OF A PRESERVED PALEOSOL FROM THE HUNTLEY MOUNTAIN FORMATION IN PENNSYLVANIA
This paleosol deposit, approximately 39 cm thick, is Dusky Red (10R 3/4) with blocky ped structure with underlying relict bedding. Irregular and diffuse greenish gray mottles are present and likely represent drab halos outlining root traces forming from decayed organic matter. The features evidenced in this paleosol suggest a soil that has undergone pedogenesis during periods of wetting and drying from a fluctuating water table. Thin sections were made from vertical and horizontal oriented samples to study the micromorphology of the paleosol horizons. This is aided by X-ray diffraction to constrain the clay mineralogy of this paleosol. This paleosol deposit at the top of the Huntley Mt. Fm. offers insight as to surficial conditions of this site and the landscape at or across the Devonian-Mississippian boundary.
