Abstract

Here, the AA. report micromorphology of diagenetically altered paleosols (~ 31 Ma old) from Dagshai Formation, Himalayan Foreland. The fluvial sequence exposed along the Koshaliya River, NW Himalaya, contains 4 types of paleosols with decreasing abundance of well-developed paleosols from basal to upper part of the Dagshai Formation. Diagenesis caused compaction, cementation, re-crystallization and coalification. Despite diagenetic alteration, evidence of paleopedogenic processes is still well-preserved in these fossil soils in the form of microstructures, b-fabrics, pedogenic calcite, bioturbation, and textural pedofeatures. Thin-section analysis helped to distinguish pedogenic and diagenetic features of lithified paleosols and to infer the paleoenvironment of the Dagshai paleosols. Paleopedology indicates tropical weathering during early Oligocene time
