About this document
Paleosols in Triassic Yanchang Formation by Carlos Zavala is a document available to read on EtoBox.
The document summarizes a study of paleosols in the Triassic Yanchang Formation in the Ordos Basin in China. Multiple paleosol levels were identified in over 1000 meters of stratigraphy. Paleosols at the lower section indicate arid conditions, while those in the middle section indicate semiarid to semihumid conditions based on root structures. Paleosols in the upper section suggest returning to arid and semiarid climates. Exceptionally preserved fossil trees immersed in sandstone in the lower arid paleosols
