Unit summary

Rank: Not recorded
Status: Published
Age: Cenozoic · Paleogene–Neogene · Middle MioceneMiddle Miocene (Serravallian; ~13.8-11.6 Ma)
Named by: HSC (1961)
Type locality: Makran Flysch Province, Balochistan Basin26.9706°N, 64.0887°E
Thickness: 1000-2000 m
Lithology: Predominantly sandstone with marine shale; clastic turbidites deposited as stacked deep-sea fan sequences.
Synonyms: Not recorded

The thick Oligocene–Miocene turbidite sandstones that build the ridges of the Makran wedge — the region's main potential gas/oil reservoir.

Major turbidite sequence in Makran. Part of world's largest accretionary wedge complex.

Band colour = period; texture = dominant rock type. Lines between bands mark the contact type. True scale makes height ∝ recorded thickness; hatched = thickness not recorded. Ages approximate, for ordering.

This unit (highlighted) within its province column; faded ends continue above and below. Line style marks the contact type.

Economic significance

Reservoir Seal

The principal potential RESERVOIR unit of the Makran; its stacked turbidite sandstones have porosities up to ~18% and form exploration targets, with Hoshab/Parkini shales as source and seal.

Remarks

A very thick Oligocene–Early Miocene turbidite succession of the Khojak–Panjgur submarine-fan complex, the ridge-forming backbone of the Makran accretionary wedge — one of the largest accretionary prisms on Earth, fed by Himalayan-derived (Katawaz delta) detritus.

Lexicon status: Appears in a single-author Geological Survey of Pakistan memoir (Malkani & Mahmood 2017), not cross-confirmed against the Shah lexicon. The Stratigraphic Committee of Pakistan is largely inactive, so documented provenance — not formal ratification — is the available signal.
