Reviewer-supplied. Micropalaeontological, nannofossil and palynological analysis of Paleocene-Eocene sections of the Northern Sulaiman Ranges (BP field survey), placing the lithostratigraphic units in a global bio- and sequence-stratigraphic framework with palaeoenvironmental interpretations.

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 Baska Formation Paleogene
  • Age: Jones (1997): latest Early–earliest Middle Eocene, from the nummulitid Assilina maior punctulata (Cuisian Supérieur–Lutetian Basal of Schaub 1981; NP14–NP15) and planktonic foraminifera 'Globigerina' lozanoi (P8–P10) and Globorotalia (Acarinina) ex gr. pentacamerata (P8–?P9).
  • Depositional environment: Jones (1997): a low-energy back-bank lagoon characterised by Miliolida, with sea-grasses (epiphytic discorbids) and rare globigerinids indicating open-ocean influence; deposited during the regressive third-order sequence TA3.1 of Haq et al. (1987).
• Cenozoic Domanda Formation Paleogene
  • Age: Jones (1997), Domanda Shale (Kirthar Formation member): 'mid' Middle Eocene, from the larger benthonic alveolinid Alveolina elliptica (Lutetian Basal–Moyen(?) of Schaub 1981; NP15–NP16/17).
  • Depositional environment: Jones (1997): a low-energy back-bank lagoon characterised by Miliolida (with soritids and alveolinids), deposited during the regressive third-order sequence TA3.4 of Haq et al. (1987); photosymbiont-controlled depth ~30–50 m.
• Cenozoic Drazinda Formation Paleogene
  • Age: Jones (1997), Drazinda Shale (Kirthar Formation member): late Middle Eocene, from the nummulitid Nummulites beaumonti (Schaub 1981; NP15–NP18) and planktonic foraminifera Globigerina praebulloides (no older than P14) and Truncorotaloides libyaensis (P11–P14).
  • Depositional environment: Jones (1997): the Drazinda Member is associated with the regressive third-order sequence TA3.6 of Haq et al. (1987); a prevalence of the dinocysts Selenopemphix and Wetzeliella points to a proximal/regressive environment.
• Cenozoic Dungan Formation Paleogene
  • Age: Jones (1997), Northern Sulaiman Ranges: a Late Paleocene to Early Eocene age is indicated by planktonic foraminifera Globorotalia (Morozovella) ex gr. angulata/conicotruncata (Zones P3–P5 of Blow 1979) and G. (M.) ex gr. subbotinae (P6–P8).
• Cenozoic Ghazij Group Paleogene
  • Depositional environment: Jones (1997): the Ghazij (reported as the Ghazij Formation) yielded only an impoverished, largely non-marine palynoflora (rare angiosperm/Gramineae pollen and spores, with reworked Early Cretaceous dinocysts); the absence of marine palynomorphs gives negative evidence for a non-marine palaeoenvironment. No age could be drawn from this study — the Early Eocene age rests on previously published work.
• Cenozoic Habib Rahi Formation Paleogene
  • Age: Jones (1997), Habib Rahi Limestone (Kirthar Formation member): early Middle Eocene, from the larger benthonic nummulitid Assilina maior punctulata (Cuisian Supérieur–Lutetian Basal of Schaub 1981; NP14–NP15) and calcareous nannofossils Discoaster saipanensis, Nannotetrina spp. and Sphenolithus pseudoradians.
  • Geological significance: Jones (1997): the Habib Rahi Member is associated with the transgressive third-order sequences TA3.2–TA3.3 of Haq et al. (1987); its nummulitic/nummulithoclastic grainstones (Rotaliida) grade to laminated basinal shales, and A-form-dominated nummulitid populations plot in the 'toe of slope' field.
• Cenozoic Kirthar Formation Paleogene
  • Age: Jones (1997): larger benthonic nummulitids, planktonic foraminifera and calcareous nannofossils indicate an essentially Middle–?Late Eocene age, resolved through the Kirthar Formation's four members — Habib Rahi (early Middle Eocene), Domanda ('mid' Middle Eocene), Pir Koh ('mid' Middle Eocene) and Drazinda (late Middle Eocene).
  • Depositional environment: Jones (1997): the Kirthar records a range of carbonate-platform and associated basinal sub-environments — back-bank lagoon (Miliolida), proximal high-energy bank/fore-bank (nummulitid–discocyclinid grainstone) and distal basinal (stress-tolerant Buliminida) — its members tracking successive Haq et al. (1987) third-order sequences TA3.2–TA3.6.
• Cenozoic Pirkoh Formation Paleogene
  • Age: Jones (1997), Pir Koh Limestone (Kirthar Formation member): 'mid' Middle Eocene, from the nummulitids Assilina exponens and Nummulites beaumonti (Lutetian Moyen–Biarritzian of Schaub 1981; NP15–NP18), planktonic foraminifera Globorotalia (Acarinina) ex gr. bullbrooki (P8b–P12) and Orbulinoides beckmanni (P13), and nannofossils Chiasmolithus grandis and Sphenolithus predistensus.
  • Geological significance: Jones (1997): the Pir Koh Member is associated with the transgressive third-order sequence TA3.5 of Haq et al. (1987), spanning laminated shale through mudstone to limestone across carbonate-platform and basinal sub-environments.
