Full-text (user-supplied). Single-author IGCP-608 symposium extended abstract giving a basin-wide lithostratigraphic listing. Weak/tertiary: largely redundant with the existing dataset and several of its synonymies (Hangu = Patala; Sakesar = Lockhart = Margala Hill; Domanda = Sirki; Gurguri = Chashmai) contradict better biostratigraphy (e.g. Afzal, Williams & Aldridge 2009) and are NOT adopted. Used only for a few distinctive, defensible facts recorded as attributed revisionNotes: Deccan-volcanism evidence in the Pab, Khadro and Bara formations; the Datta Formation terrestrial (upper Indus) to marine (uppermost Indus) facies substitution; and the Girdu and Bawata members of the Rakhi Gaj Formation.

This page is the reverse of each unit's per-field citations — it shows exactly what this reference supports, making the dataset's “no source, no fact” rule browsable both ways.

Units citing this source

• Cenozoic Bara Formation Paleogene
  • Geological significance: Malkani (2016) describes the Paleocene Bara Formation of the Kirthar (lower Indus) Basin as sandstone with minor limestone, coal and volcanics, the latter attributed to Deccan volcanism near the K/Pg boundary.
• Mesozoic Datta Formation Jurassic
  • Depositional environment: Malkani (2016) notes that the Datta Formation is a lateral facies substitution: deposited in terrestrial (fluvial) environments in the upper Indus (Kohat-Potwar) Basin and in marine environments down-slope in the uppermost Indus (Khyber-Hazara-Kashmir) Basin. Curated environment (continental/fluvial/marginal marine) retained.
• Cenozoic Khadro Formation Paleogene
  • Geological significance: Malkani (2016) records volcanics derived from Deccan volcanism within the Paleocene Khadro Formation (sandstone, shale, limestone and volcanics) of the Kirthar (lower Indus) Basin, corroborating the basal Khadro basaltic flows already noted in the dataset and the K/Pg Deccan signal across the Sangiali/Ranikot base.
• Mesozoic Pab Sandstone Cretaceous
  • Geological significance: Malkani (2016) reports evidence of Deccan volcanism within the Maastrichtian Pab Formation of the Sulaiman/Kirthar (middle-lower Indus) basins, consistent with the Deccan volcanic dust recorded in the overlying earliest-Paleocene Sangiali and Rakhi Gaj / Khadro formations near the K/Pg boundary.
• Cenozoic Rakhi Gaj Formation Paleogene
  • Member units: Malkani (2016) subdivides the Rakhi Gaj Formation into a Girdu Member (glauconitic and hematitic sandstone) and a Bawata Member (alternating shale and sandstone), within his Paleocene Sangiali Group. Recorded for provenance; member units not created in the dataset.
