Full text reviewed (reviewer-supplied scan, OCR'd). Sedimentology of the Early Eocene (by fossil content) Ghazij Formation in the Kach area, Baluchistan. Treats Ghazij as a FORMATION (not a group): 590 m thick at the Spintangi type section; conformably overlies the Dungan/Laki formations and Ranikot Group (Paleocene) and underlies the Kirthar Formation (Upper Eocene). Dominantly variegated calcareous shales with subordinate sandstone and conglomerate, alabaster and coal seams; deltaic origin with turbidites in the lower shale-dominant part and an upper shale-dominant marine-transgressive top; palaeocurrents generally east-to-west. Earlier workers subdivided it into the Baska Shales (Alabaster Member) and Matap Conglomerate Member (Oldham 1890; Williams 1959; HSC 1961). Coal mined at Sor Range, Degari, Duki, Mach and Sharigh.

Units citing this source

• Cenozoic Ghazij Group Paleogene
  • Depositional environment: Corroborated by Kassi et al. (1987): the Ghazij succession in the Kach area, Baluchistan, has a deltaic origin — rhythmic/graded turbidite sandstones in the lower shale-dominant part, a coarsening-up middle and a fining-up, shale-dominant transgressive top; palaeocurrents generally east-to-west. Consistent with the existing 'deltaic' interpretation.
  • Economic importance: Kassi et al. (1987): the Ghazij is worked for coal (Sor Range, Degari, Duki, Mach, Sharigh) and alabaster (gypsum). Corroborates the existing coal note.
  • Thickness: Kassi et al. (1987): 590 m at the Spintangi type section, Baluchistan. The dataset's ~1000 m (500-1500 m) reflects the broader group across regions; the Baluchistan Ghazij type section is ~590 m. Value retained.
  • Upper contact (underlies): DISCREPANCY for review — Kassi et al. (1987): the Ghazij conformably overlies the Dungan/Laki formations and Ranikot Group (Paleocene) and UNDERLIES THE KIRTHAR FORMATION (Upper Eocene). The dataset currently records underlies = 'Kahan Group'. Kassi's Ghazij->Kirthar superposition also supports treating the Kirthar succession (Habib Rahi/Domanda/Pirkoh/Drazinda) as a separate unit above Ghazij, not as Ghazij members (see the taxonomy proposal).
  • Member units: RANK note for the taxonomy review — Kassi et al. (1987) and earlier workers (Oldham 1890; Williams 1959; HSC 1961) treat Ghazij as a FORMATION subdivided into the Baska Shales (Alabaster Member) and Matap Conglomerate Member, whereas this dataset carries it as a 'Ghazij Group'. The Formation-vs-Group rank for Ghazij is exactly the kind of inconsistency flagged in the taxonomy proposal; left as-is pending GSP/SCP + reviewer decision.
