Synopsis of the Siwalik Group of the Potwar Plateau as a ~100 kyr-resolution mammal-bearing fluvial record, dated by magnetostratigraphy. Lithostratigraphy: Kamlial (>50% sand), Chinji (red silt with paleosols/ponding), Nagri (thick multistoried sands), Dhok Pathan (channel + floodplain), Tatrot and (in India) Pinjor formations, above the Early Miocene Murree Formation. Fluvial floodplain silts/sands with vertical lithologic variation primarily tectonically controlled.

Units citing this source

• Cenozoic Chinji Formation Neogene
  • Lithology: Flynn et al. (2016): the Chinji Formation is dominated by fine-grained red silt with abundant paleosols and evidence of ponding, contrasting with the sandier Kamlial below and Nagri above.
• Cenozoic Dhok Pathan Formation Neogene
  • Lithology: Flynn et al. (2016): the Dhok Pathan Formation comprises channel sand deposits interbedded with finer floodplain silts, succeeding the thick-sand Nagri Formation; Pliocene Upper Siwalik units above include conglomeratic sands.
• Cenozoic Kamlial Formation Neogene
  • Lithology: Flynn et al. (2016): the late Early Miocene Kamlial Formation contains >50% sand, distinguishing it from the overlying finer-grained red silt of the Chinji Formation; it is the basal Siwalik formation of the Potwar above the Murree Formation.
• Cenozoic Nagri Formation Neogene
  • Lithology: Flynn et al. (2016): the Late Miocene Nagri Formation is dominated by thick, multi-storied sand bodies, in contrast to the finer-grained Chinji below and Dhok Pathan above.
• Cenozoic Siwalik Group Neogene
  • Geological significance: Flynn et al. (2016): the Siwalik Group of the Potwar Plateau is one of the world's longest continuous continental mammal records — dominantly fluvial floodplain silts and sands dated by palaeomagnetic reversal stratigraphy to a resolution of ~100,000 years. Its formations (Kamlial, Chinji, Nagri, Dhok Pathan, Tatrot, and the Indian Pinjor) are distinguished chiefly by sand-body proportion, with vertical lithologic variation primarily tectonically controlled.
