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.

Age & correlation (1)

Kazmi & Abbasi (2008) gap-fill: the Langrial Limestone is a Late Precambrian unit of the Hazara Group (a member alongside the Miranjani Limestone; Latif 1970), Hazara/foreland — not Karakoram. Blank age gap-filled to Late Precambrian; the earlier note that it is a member of the Hazara Formation/Group and misclustered stands.

Geological significance (1)

Data-quality flag (reviewer audit, 2026-07-30): Kazmi & Jan (1997) carry "Langrial Limestone" only inside a historical correlation table (after Marks & Mohammad Ali 1962) as a superseded MEMBER-level subdivision of the Precambrian Hazara Formation — no descriptive text, age or type section. It is a Hazara/foreland unit, NOT a Karakoram unit as currently clustered in the DB. Recommend reclassifying (informal member of the Hazara Formation; correct the regional tag) or removal.

Reviewer confidence: high

Every fact on this page is source-cited. This entry is part of the peer-archived Pakistan Stratigraphy Dataset (doi.org/10.5281/zenodo.21363991, CC‑BY‑4.0).

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.
